Research

ICPI and the ICPI Foundation for Education and Research advance knowledge in interlocking concrete pavement through technical research . In 2012 , several research projects were of note .
University of New Hampshire PICP Research
Started two years ago , the University of New Hampshire Stormwater Center ( UNHSC ) monitored runoff from a 13,500 sf ( 1,350 m2 ) PICP site in the university campus center . Monitoring concluded in June 2012 and a final report was issued by the UNH Stormwater Center in late October . The PICP test area is on high infiltration soils and provided little outflow via underdrains from over 15 storms . When approved by the Foundation , the report will be available on the UNHSC website with a summary fact sheet , and will accompany other reports on pervious concrete and porous asphalt performance research . UNHSC research obtains substantial exposure at stormwater and LID conferences .
Staff contributed to a seminar on PICP in June 2012 at UNHSC where 40 persons attended , as well as several ICPI members . There will likely be a second UNHSC seminar in spring 2013 . UNHSC is viewed by state and municipal stormwater agencies as a major provider of unbiased design and performance information .
This project ’ s success is due to the Foundation and ICPI jointly funding the research contract , plus contributions from ICPI members , the Northeast Concrete Masonry Association , and the Northeastern Cement Shippers Association for materials and construction of the PICP test area .
University of Pittsburgh Sidewalk Smoothness Study Update
The ICPI Foundation co-funded a research project with the University of Pittsburgh to develop a sidewalk smoothness measurement device . The University of Pittsburgh is the same group that conducted wheelchair-pavement interaction studies for ICPI and BIA in 2002 and 2004 . The work parallels a separate University — U . S . Access Board contract to develop acceptance criteria for sidewalk smoothness for wheelchair users , and an eventual ASTM standard for measuring smoothness . This acceptance criterion rationalizes wheelchair user comfort and sidewalk accessibility , while the Foundation and BIA are funding the technology to measure smoothness .
The pavement smoothness measurement device should be prototyped and tested by summer 2013 . A key aspect of the University ’ s work for the Foundation and BIA is U . S . Access Board acceptance of the measurement technology and inclusion in the ADA Design Guidelines , or eventually in an ASTM standard . ICPI ’ s participation influences the outcome and possibly prevents loss of market share . Development of smoothness / vibration standards favorable to segmental pavements could better position the industry over the long term , ultimately selling more pavers .
UC Davis PICP Structural Testing Moving Forward
As a pressing need for PICP market development , structural testing and validated design charts rank high . To address this need , the ICPI Foundation Trustees approved funding , with the California Nevada Cement Association and the Concrete Masonry Association of California and Nevada members for full-scale structural testing and development of design charts for PICP . Modeling , laboratory as well as full-scale load testing of PICP will be done by the University of California Pavement Research Center ( UCPRC ) in Davis . The ICPI Foundation support includes some of the project costs , construction costs , and project administration . Additional Foundation support includes review of the test program deliverables and review of the data for application to freeze-thaw areas by an outside consultant . About 2,800 sf of permeable pavers are being donated by an ICPI member . Caltrans has agreed to provide technical review of the project and its results . This will be important in influencing Caltrans PICP design guidance .
TRCA PICP Research Funding Approved
At the 2012 ICPI Summer meeting , the Foundation approved funding for the Toronto and Region Conservation Authority ( TRCA ) to continue monitoring of various permeable pavement types ( porous asphalt , pervious concrete and PICP ) at their parking lot near Toronto . Funds are leveraged from other contributors who with ICPI helped launch monitoring over two years . The TRCA funding extends monitoring another two years . The two PICP parking lot installations at TRCA offices utilize pavers from Foundation donors .
