  • ASCE LID Retrofit Project

    ASCE LID Retrofit Project: This effort is part of a retrofit of several LID technologies within a large asphalt parking lot that surrounds the ASCE office building. As the promoters of LID tools, ASCE leadership wanted to set the example at the home office. The PICP was designed according to a national standard, ASCE 68-18 on Permeable Interlocking Concrete Pavement. The pavement can store and infiltrate rainfall for a maximum 100-year storm.This project was completed at the end of October 2020 involving an installation of over 4,000 sf of PICP with base and drainage. This provided the crowning example among several low impact development (LID) technologies demonstrated at the ASCE headquarters building in Reston, VA.

  • Municipal ICP Performance Modeling

    Municipal ICP Performance Modeling - This project helps determine total life performance costs under various maintenance cost scenarios and comparing them to that for asphalt and concrete. While the conclusions from these studies don't offer a compelling life-cycle cost analysis (LCCA) for municipalities to switch from asphalt or concrete pavements to ICP, there are specific situations where ICP has a lower life-cycle costs. These include: Moderate to high traffic loads and moderate to high soil subgrade support; Discount rates 3% or lower over a 50-year analysis period; Sidewalks; and Utility cuts and remaining pavement life.

  • OSU Research on Permeable Pavements

    Oklahoma State University Research- Developing deflection acceptance criteria for compacted, open-graded aggregate bases for permeable pavements using lightweight deflectometers (LWDS): An extensive literature review was delivered last January per the contract and reviewed by the Foundation Program Committee. The project was placed on hold in March 2020 as OSU was closed due to Covid-19. OSU reopened and the project is moving forward. Additional work includes laboratory tests in a large test bed with compacted aggregate, full-scale field testing on open-graded aggregate bases typical to PICP are to be built next spring and tested. This will be accompanied by finite element modeling and a compaction control specification written in AASHTO format for eventual submission to AASHTO.
