From the Chairman:Heading into Our Third Decade – Looking Back and ForwardWith our strategic plan goals in mind, 2015 saw the launch of new programs and initiatives while maintainingsuccessful ones. At the top of the list is a Board Special committee recommending that ICPI develop design andconstruction resources for paving slabs. This initiative positions ICPI to better represent this part of the industrynow experiencing unprecedented growth in residential and commercial markets. The annual ICPI Industry SalesSurvey for 2014 indicates that paving slab sales are about 16% of total concrete segmental paving unit production,up from 14% in 2013. This is complemented by 11.1% growth for pavers in the U.S. and Canada in 2014. To support this growth, the ICPI Foundation funded finite element modeling research on paving slab and planksto develop structural design charts. With input from the Technical and Construction Committees, design andconstruction guidance will be published in Tech Specs in 2016. This initiative includes development of an ASTMproduct standard for paving slabs. The ICPI website experienced a complete renovation showcasing a streamlined and inspiring way to use the as-sociation’s resources. The redesign allows designers, contractors and homeowners to obtain information, resourcesand ideas pertinent to them. This remake provides an opportunity to improve navigation, update databases andtechnical information. The ease of use makes the ICPI website the premier online technical resource for pavingsystem users and for members. The Hardscape North America trade show exhibition continues to grow with support from the Distributors’ DayWorkshop, ICPI installer certification classes, project awards, many outdoor demonstrations, the installer compe-tition, and synergy from the GIE+ EXPO. HNA showcases products and equipment aimed at mostly residentialcontractors who install over 75% of all concrete paving products. The challenge ahead is ever expanding exhibitorswhile maintaining a fresh, relevant and innovative show program that brings back past attendees while attractingfirst timers. At the ICPI Summer Meeting, an HNA Strategic Planning Session provided a range of ideas and initia-tives to help achieve this. On the U.S. legislative front, we are pleased that a five year transportation bill was passed. Continued PaverPACsupport underscores legislation providing technology transfer of permeable pavements to state departments oftransportation. We have presented programs on permeable pavement the national level for FHWA and to stateDOTs in Ohio and Colorado. We will continue to expand presentations to more states DOTs via the FHWA LocalTechnical Assistance Program (LTAP). In Canada, we have found the Federation of Canadian Municipalities to be theplace to present stormwater runoff solutions with permeable interlocking concrete pavements. The ICPI Foundation for Education and Research continues supporting ICPI by providing much needed researchfrom structural research for PICP at University of California – Davis to Segmental Paving Slab Modeling/StructuralAnalysis. These research projects have given us groundbreaking technical data to present to engineers and munici-pal officials at regional programs sponsored by members in such locations as the University of New Hampshire andthe City of Toronto. Speaking of strategic planning, every three years, ICPI revisits and updates its strategic plan. The 2015 SummerMeeting general session included a brainstorming session among 150 members on new ideas and directions.These were included in the mix when the Strategic Planning Committee met in Chicago in the Fall to update thevision and mission statements, and develop overall objectives for the next three years. These will be presented tothe members and Board at the 2016 Annual Meeting.   As I conclude my chairmanship in early 2016, I look back with appreciation for everyone’s support that enabledus to accomplish much over the past two years. We have some great opportunities ahead and I look forward toadvancing the leading association on segmental concrete paving systems with you.  Sincerely, David Pitre ICPI Annual Report 2015 ICPI Board Chair4

Commercial Market Promotion and EducationThe commercial market includes specified projects for commercial, municipal, institu-tional, industrial uses, as well as single and multi-family housing developments. ICPI’sstrategic plan focuses on expanding these markets as designers and project ownerslook to trade association for technical support affirming and sometimes expandingon a supplier’s information. Along these lines, staff and members supported a rangeof activities in 2015. Direct support was provided to provincial, state and municipalagencies in developing permeable pavement design guidelines. Agencies supportedwith technical information and guidance included the Federal Highway Administra-tion, the Federal Aviation Administration, Caltrans, District of Columbia Department ofTransportation, the Ontario Ministry of Transportation, the Denver Urban Drainage andFlood Control District, and many U.S. and Canadian municipalities.Workshops, Seminars, and Conference Sessions Presented by ICPI StaffA strategic plan goal to increase presentations at regional and national conferences.Staff presented at 32 events to help achieve acceptance of ICP and PICP. These eventsincluded:Event Topic LocationConstruct Canada Construction and Performance of Permeable Pavement Toronto, ON Toronto, ONTRIECA Maintenance of PICP and Full-scale Structural Testing and Development of Design Washington, DC Guidelines for Permeable Interlocking Concrete Pavement Toronto, ONAmerican Concrete Institute Columbus, OHConvention Permeable Pavement Infiltration Testing Chicago, ILCity of Toronto and Permeable Pavements Seminar Castle Rock, COMetropolitan AreaOhio Local Technical Assistance Permeable Pavements SeminarProgram Trade ShowASLA ConventionGreenbuild Convention Trade Show Permeable Pavements SeminarColorado Local TechnicalAssistance ProgramWebinars for Design Professionals, Contractors & Sales PersonnelWebinars provide a cost-effective, convenient and timely education platform for building awareness of segmental concrete pavement amongdesign professionals, offering installation best practices and guidelines while providing resources and techniques to sales personnel.

Commercial Market Promotion and Education continued from p. 5Presentations for Design ProfessionalsICPI presentations provide an excellent sales-through-education opportunity to designprofessionals and city officials. Offering thesepresentations is an effective way to buildlongstanding customer relationships. Most designprofessionals must earn continuing educationcredits to maintain their professional licenses. All ICPIpresentations are registered with AIA, ASLA and/orGBCI and each provides one continuing educationhour. In 2015, ICPI members and staff deliveredICPI presentations to approximately 865 designprofessionals across the U.S. and Canada.Commercial Sales CourseBack for a third year, ICPI with NCMA presentedan education program for sales representatives Commercial Sales Course in Chicago taught by Jay Womack, ASLAsupporting the commercial market. The courseimproves technical knowledge and collaborativeinteraction with design professionals, developers and municipal officials. Content includes presentations by two engineers and two landscapearchitects, an overview of competitive systems and technical background on interlocking and permeable interlocking concrete pavements,segmental retaining walls and articulating concrete block. Related software, product specifications, plan review and bidding procedures arealso covered. The course held December 1-3, 2015 in Chicago, IL saw 34 attendees. We anticipate additional information on paving slab designand construction at future schools.LTAP Technical SupportJointly funded by the Federal Highway Administration, state universities and some State Departments of Transportation, the Local TechnicalAssistance Program (LTAP) provides technical support and training to state and local road agencies. ICPI has been welcomed into thiscommunity thanks to national legislation encouraging technology transfer of permeable pavements to states and cities. LTAP is emerging as asuperb platform for increasing awareness of permeable pavements. In April 2015, ICPI presented at a seminar attended by 150 municipal officials on permeable pavements organized by the Ohio LTAP, OhioDOT and the Ohio Department of Natural Resources. This led to ICPI staff invited to give a brief presentation at the national LTAP conferenceof some 300 LTAP staff from most states across the U.S. ICPI offered permeable pavement seminars for LTAP training. Interest in conductingpresentations was expressed by Colorado, Nebraska, New Jersey and Florida LTAPs. The presentation resulted in ICPI participating in apermeable pavements seminar organized by the Colorado LTAP in December 2015. ICPI will reach out to other LTAPs in 2016.PCA’s 2015 Professors WorkshopMore than 30 professors from around the country participated July 20-24 at the PCA offices in Skokie, Illinois. The workshop providesengineering, architecture, and construction management faculty tools to teach the latest developments in concrete design, constructionand materials. Attendees chose from three tracks: Concrete Materials Properties; Engineering and Economics of Concrete Buildings; Design,Construction; and Performance of Concrete. Robert Bowers, P.Eng, ICPI’s Director of Engineering, presented to 12 university professors onICPI, interlocking concrete pavements and permeable interlocking concrete pavements. ICPI co-sponsored the event with several otherorganizations.6 ICPI Annual Report 2015

Government AffairsRepresenting the concrete paver industry, ICPI continues implementing legislative and regulato-ry lobbying initiatives benefiting member business interests. A central feature of ICPI’s lobbyingactivities is to indelibly brand permeable interlocking concrete pavements (PICP) as an environmen-tally friendly, “green” technology that can provide substantial stormwater runoff reduction, reduceflooding, improve water quality by enhancing filtration of stormwater runoff, retain local hydrology,and facilitate municipal low impact development objectives. ICPI is urging Congress and key federalagencies that PICP can play a major role in emerging, evolving federal policies to improve the envi-ronment, and should be promoted and integrated in federal policy.Transportation Authorization Passes; Action Shifts to THUD AppropriationsAt press time, the House and Senate have passed the FAST Act. At this writing, ICPI members, staff and consultants have engaged a conferencecall to discuss concepts to propose to the THUD Appropriations Committees. The first meeting with THUD Appropriations Committee staff isscheduled for mid-December, prior to the holiday adjournment. Senator David Vitter (R-LA) and Cong. Frank LoBiondo (R-NJ) worked very closely with ICPI in the lead up to the FAST Act, the reauthorizationof the Transportation Bill. Cong. LoBiondo introduced a supportive statement regarding PICP in The Congressional Record as part of the FASTAct debate and legislative history that the Appropriations Committees will use in determining funding for FHWA.OSHA to Publish Final Silica Regulation as Soon as February 2016At press time, OSHA has stated in the federal government’s Unified Agenda that it intends to publish a final rule on silica exposure as early asFebruary 2016. ICPI supports a funding amendment by Sen. John Hoeven (R-ND) offered an amendment to the FY2016 Labor, HHS, Education Appropria-tions bill that would require OSHA to engage in two new efforts: (1) convene a new Small Business Regulatory Enforcement Fairness Act of 1996 (SBREFA) panel to fully assess the economic impact of the proposed rule on small businesses, and (2) conduct a separate independent review by the National Academy of Sciences. ICPI signed a joint industry letter supporting the Hoeven Amendment which was accepted in committee. ICPI signed a new letter makingthe same arguments in late November 2015 as House and Senate negotiators were considering an end-of-year package of appropriations bills.A Continuing Resolution/ Omnibus is the most likely vehicle to constrain OSHA from full-scale implementation once the final rule is published.WOTUS Rule Faces Court, Political Opposition, but has Continuing ImpactThe U.S. Corps of Engineers and U.S. EPA finalized and signed the Waters of the U.S. (WOTUS) rule into effect on May 27 in a ceremony back-dropped by the Anacostia River and Navy Yard in Washington DC. ICPI was invited to attend the signing and did so. States and other opponents of the WOTUS rule filed suit in federal court requesting a stay until the court may consider legal challenges tothe rule. However, the mere existence of the rule, and the clear determination demonstrated by EPA and the U.S. Corps of Engineers to pursuethis issue, make it a prudent practice for state and local governments, and the private sector, to ramp up their efforts to mitigate stormwaterrunoff. ICPI can adopt this message and, of course, offer PICP as a ready safe-harbor solution.Immigration and the H-2B Worker visa program, DHS/DOL rulesImmigration has developed into a key issue in the 2016 Presidential election and has actually expanded into a national security issue basedupon the San Bernardino terrorism shootings. At the moment, it is a campaign issue but not much more. We do not expect major changes tothe H-2B worker visa program until another President occupies the Oval Office.Depreciation Bonus and Section 179 Provisions Possibly on FY2016 Funding CompromiseAt press time, House and Senate negotiators are putting the final touches on an end-of-year spending plan that may include extensions ofbonus depreciation and/or higher limits for Section 179 expensing in the U.S. tax code.Congress Passes Trade Bill to Reduce “Red Tape” in Cross-Border TradeThe heart of the legislation is facilitation. Part of the bill is designed to allow goods and business executives to move more freely across theborders for legitimate business and trade activity. As an international trade association with members conducting cross-border trade, ICPIsupported the bill. Continued on p. 12ICPI Annual Report 2015 11

Government Affairs continued from p. 11PaverPAC to See Increased Requests for Campaign Help in 20162016 will indeed be a crucial election season with the White House, all House seats, and one-third of the Senate seats up for election. ICPI andPaverPAC use highly targeted efforts supporting Members of Congress who have demonstrated knowledge, appreciation and support for agrowing ICP industry. PaverPAC is in strong condition as a tool to support ICPI’s legislative activities on Capitol Hill, but PACs require constant, ongoing mainte-nance. As we begin to see greater campaign attention from candidates with respect to the 2016 elections, we anticipate many more invitationsfor PaverPAC. It can respond well and with frequency, but strong PAC reception attendance and member support is essential.Canadian Government Relations SubcommitteeICPI continues to work with the FCM Corporate Partnership, including participation in the SustainabilityConference Feb. 10-12, 2015 in London, ON and FCM Annual Meeting, June 5-7, 2015 in Edmonton, AB.ICPI held a PICP training session for the City of Toronto with 120 attendees and sponsored by seven mem-bers.ICPI and PICP presented at the Transportation Association of Canada’s Annual Meeting Sept. 27, 2015.PICP presentations were held in Guelph, ON Oct 15 and North Bay, ON Oct 29. Staff met with the City ofNorth Bay Public Works Director to discuss the maintenance of their ICP Main street which is over 30 yearsold and the basis of a case study, life cycle cost research and articles in the Interlock Design magazine.ICPI Purchase of Office CondominiumMeets ExpectationsAs promised, the office Office Facility Expensescondominium purchased byICPI members in December $140,000 $125,135 $116,044 $107,947of 2014, constructed and $120,000 FY 14occupied in February of 2015has met expectations.

ICPI Foundation for Education and ResearchThe ICPI Foundation for Education and Research advances knowledge in interlocking concretepavement through technical research and development of education programs. In 2015, severalresearch projects were of note that support industry development and technical expertise.Paving Slab Structural Design is First for the U.S. and CanadaSegmental Paving Slab Modeling/Structural Analysis – Concrete paving slabs are units that require two or more hands to install. These units areseeing increased use in residential, commercial and municipal applications especially with some exposure to vehicular traffic. Applied ResearchAssociates, Inc. developed pavement thickness recommendations for paving slabs, thin paving units and paving planks. The recommenda-tions are for various bedding, base and soil types. The project reviewed international research and design literature, and then conducted finiteelement modeling. The charts will be included in an ICPI Tech Spec on paving slabs structural design. Designer Confidence Raised with Validation of PICP Subbase Thickness Design Charts University of California Davis PICP Full-Scale, Accelerated Load Tests – The final report posted on UC Davis.edu website include PICP subbase thickness design charts that validate those published by ICPI in 2011 based on the AASHTO 1993 flexible pavement design method. A benefit of the UC Davis design charts is they provide thinner and more economical subbases in semi-arid climates since subbase thicknesses are based on the number days with water in it. The research report was presented to Caltrans on July 29, 2015 and Caltrans agreed to include the UC Davis design charts in their Pervious Pavements Design Guide. The design charts will be in the draft ASCE PICP national design standard expected in 2016. The UC Davis work is being published and presented at various conferences including ASCE and the 2015 International Conference on Concrete Block Paving in Dresden, Germany.PICP Works in Low-Infiltration Clay SoilsNorth Carolina State University PICP Monitoring Research – Multiple studies haveshown PICP is an effective tool to improve stormwater runoff hydrology and wa-ter quality even when sited over high infiltration soils. This project researched PICPefficacy over nearly impermeable soils (approximately 0.01 in/hr or 0.254 mm/hr) or inDurham, NC from March 2014 through April 2015. Four parking stalls (540 ft2 or 50 m2)were retrofitted with PICP with a very small contributing impervious area. PICP designfollowed design guidelines outlined in Chapter 18 of the North Carolina Departmentof Environment and Natural Resources (NCDENR) BMP manual. Results through 13 months of monitoring indicated 22% volume reduction viasubgrade infiltration and evaporation. Inter-event infiltration of water within the 6 inch(150 mm) thick subbase created storage to capture over 70% of the runoff volumefrom storm events less than 0.30 inches and peak flows were significantly reduced by amedian of 84%. This small PICP in Durham, NC demonstrated PICP’s ability to work in low infiltration clay soilsICPI Annual Report 2015 Continued on p. 14 13

ICPI Foundation for Education and Research continued from p. 13Supporting Landscape Architects Need for Landscape Performance Instruction at UniversitiesLandscape Architecture Foundation (LAF) mini-grants to teach landscape performance – Ten university landscape architecture programswere granted money to teach landscape performance, document the syllabus, class/studio assignments, student deliverables and reflections.This project accelerates awareness and practice of evaluating the performance of landscape designs as landscape architecture professionalpractice is using this approach in selling services and in the design process. These deliverables are posted on the LAF landscape performancewebsite at landscapeperformance.org/ resources-for-educators. LAF hosted a webinar on these deliverables and recording is available forreview. The material includes some performance evaluations of PICP and ICP. Overall, there is a wide range of models used by students to char-acterize landscape performance by practicing landscape architects, academics and students.Articulating Landscape Performance of Segmental Concrete Paving SystemsEnhancing the LAF Landscape Performance Series Website with Performance of Segmental Concrete Pavements – A three-year grant supportsexpansion of this website to include information and instruction on measuring performance of segmental pavements. This includes providingcase study ideas, curating case study collections, providing input on social media and blogs, and development of online learning modules foron measuring performance of segmental paving products.Better Testing and Design Guidelines for PICPPICP Hydraulics Research by the University of Mis-souri – Two master’s students designed and built alaboratory flow testing device to measure the hori-zontal inflow and overflow from PICP. Numerous testswere conducted on PICP with 6, 10 and 12.5 mm jointsand No. 8 and 9 jointing aggregates at various slopes.Testing included clogging studies with high concentra-tions of total suspended solids. Some of the discoveriesand design insights:• Horizontal inflow rates across PICP surfaces is 11- 35% lower than vertical infiltration rate measured using ASTM C1781 Standard Test Method for Surface Infiltration Rate of Permeable Unit Pavement Systems. Differences are higher for 6 mm wide joints.• After maintenance, about recapture of near initial infiltration rates are lower for 6 mm wide joints after cleaning than wider joints.• 6 mm wide joints infiltrate well up to 2% slope; wider joints advised at higher slopes.• 6 mm joints with No. 9 aggregates clog five times faster than 12. 5 mm joints with No. 8 aggregates.• 10 and 12.5 mm wide joints indicate little differ- ence in horizontal & vertical flows at any slope.• 45° herringbone has slightly lower infiltration than 90°.• Deliverables include an Excel tool that determines Laboratory testing of the infiltration capacity of PICP helped develop new the hydraulic characteristics a site can attain. design guidance.14 ICPI Annual Report 2015

Product Category Rules Monitoring of two PICP parking lots near Toronto demonstrated favorable winter infiltration and pollutant reduction performance.The PCR is posted on ASTM’s website under Certifica-tions. The PCR was enhanced with a guidance docu-ment for paver manufacturers on creating life cycleassessments and environmental product declarations.Additionally, deliverables included a cycle inventorytool (Excel sheet) for manufacturers to use in preparingfor a life cycle assessment and environmental productdeclarations. This accompanies the guidance documentsupported by this grant. In early 2016, a webinar will berecorded on how to use the inventory tool as a means tocatalog all energy and material flows through a manufac-turing plant. This is an essential step in conducting a lifecycle assessment which also provides the foundation forenvironmental product declarations.Monitoring and Cleaning PICP in a Cold ClimateToronto & Region Conservation Authority demonstratesPICP cold climate performance –The research facilityconsists of four ~230 m2 pavement areas. Two are PICP,and one is pervious concrete, and another is traditionalasphalt. Fifty-eight rain events had been sampled for waterquality and analyzed for solids, nutrients, metals, roadsalt constituents, and general chemistry. Overall, themedian concentrations of most stormwater pollutantswere lower in the permeable pavement effluent thanin asphalt runoff. These include total suspended solids,ammonia-ammonium nitrogen, nitrate nitrogen, totalnitrogen, total phosphorus, zinc, copper, iron and oil/grease (solvent extractable). Net reductions in pollutantmass were even more pronounced for these and otherpollutants because, on a unit area basis, 47% less storm-water was discharged from the permeable pavementplots than the asphalt.ICPI Annual Report 2015 15

Chris Ross and David Bender Receivethe ICPI Lifetime Achievement Award Chris Ross served as ICPI’s Chairman-elect in 1998 and 1999, and then as ICPI Chairman in 1999 and 2000. With his oversight, he supported the transition of ICPI from a small association management company to Bostrom Corp. who helped grow ICPI from a $700,000 in 1998 to $2 million plus budget in 2007. Under Mr. Ross’ chairmanship, ICPI laid some foundations that their board and committees rely on today. Some of these include the ICPI policy manual, policies on financial reserves, development of the certification courses, and regional meetings. The ICPI Foundation was created while he was chair.Steve Berry presented award to Chris RossDavid Bender established Pavestone Company, now one of the Elliot Bender presented award to his father, David Benderlargest paver manufacturing companies in North America. He thenestablished Pavestone Plus (later renamed Navastone) where he workedfor the next 20 years. Iin 2007 he completed the sale of his companyto Hanson Building Products. His company is a charter member ofICPI. Soon after its establishment, Mr. Bender led the associationserving as chairman from 1995-1997. He is attributed with severalleadership accomplishments that helped shape the association andindustry. One of these was the development of the ICPI Concrete PaverInstaller Certification Program which today has had more than 25,000participants.ICPI Meetings Connect Members with Industry LeadersA central component to advancing the industry is connecting with colleagues and key industry stakeholders at ICPI’sAnnual and Summer meetings. Members collectively advance the industry and gain access to resources not availableanywhere else. The 2015 featured lifetime achievement awards and the summer meeting featured the Innovative Tech-nologies Forum where Alliance presented research on their base board system, and Tencate Mirafi presented researchdemonstrating augmented structural support from geosynthetics.
