ICPI FOUNDATION
Pedestal-set Paving Slab testing
With the ICPI Strategic Plan as its mission, the ICPI Foundation lays critical groundwork via research deliverables that ultimately point to the added value of segmental concrete pavements.

As a popular and practical roofing solution, pedestal-set paving slabs currently have no national standards quantifying suitability for such applications. Load testing 2 x 2 ft dry-cast and hydraulically pressed paving slabs typically used in pedestal-set roof applications is underway at the National Concrete Masonry Association research laboratory. The research should validate a simple center-load test method and acceptance criteria for submission to ASTM. For the first testing phase, 40 paving slabs have been donated each from three ICPI member manufacturers. Results are expected in the second quarter of 2021. A second phase will test paving slabs from a range of manufacturers later in 2021. Permeable Pavement Temperature Analysis Over the past six years, the U.S. Geologic Survey in cooperation with the Wisconsin Department of Natural Resources collected surface and subsurface temperature data on a permeable pavement research installation in Madison. While impressive pollutant reduction data was well documented, temperature data on and within the pavements has not yet been analyzed. This project should better characterize the thermal response of permeable pavements to freeze-thaw cycles during winter months with implications for
