ICPI Foundation for Education and Research

Tools for Schools: This project provides grants to schools who are authorized to teach the ICPI Concrete Paver Installer course to provide paver installation tools for hands on education to compliment the classroom course.

ICP LCCA Study: This project involves surveying municipalities using interlocking concrete pavements (ICP) in streets and sidewalks for several years. The consultant will rely on cost information from previous and current municipal clients as well as a list of contacts provided by staff. The consultant developed and sent a survey requesting initial and maintenance cost information to these contacts. The survey is still proceeding and responses are expected.

Oklahoma State University Research- Developing deflection acceptance criteria for compacted, open-graded aggregate bases for permeable pavements using lightweight deflectometers (LWDS): This project included an extensive literature review, laboratory testing in a large test bed with compacted aggregate, full-scale field testing on open-graded aggregate bases typical to Permable Interlocking Concrete Pavement was tested. This was accompanied by finite element modeling and a compaction control specification written in AASHTO format for eventual submission to AASHTO.

Open-Graded Base Over Interlocking Concrete Pavement Research: This addresses a disturbing trend in some regions of placing interlocking concrete pavement over open-graded base and using stabilized joint sand with the hopes that it will remain. The first phase of the project involved laboratory aggregate testing to see which open-graded aggregates layers and gradations offer better choking and stability characteristics for use in permeable pavements. Based on that assessment, a Construction Committee task group will recommend three pavement assemblies for construction subject to vehicular loading on which outside consultants will conduct condition surveys for two years.

Program Committee: Other expenditures that help to further accomplish the organization's exempt purpose and identify potential future research projects.

Workforce Development: Empower the industry to attract, train and retain a highly qualified workforce to meet market demand.

P4 Infrastructure Exhibit: Permeable Interlocking Concrete Pavement installation of the visitor parking lot of the American Society of Civil Engineers in Reston, VA was donated by the Foundation. An exhibit in the lobby of the building was funded by the foundation monitors and displays the rainfall, and level of water in the base to educate Civil Engineers on the benefits of permeable pavement.

paveshare.org Website Rehabilitation: This 11-year old website has been completely reconstructed to a simpler, more modern and flexible platform to meet the expectations of students and educators, as well as a mobile-friendly, searchable format. Content from the previous website is being transferred to the new format. The project includes engaging landscape architecture students and educators across the United States and Canada to review the site and recommend any changes in content.

Pedestal-Set Paving Slab Testing: The reason for this research is that C1782 Standard Specification for Segmental Concrete Paving Slabs was written for at-grade applications and may not be adequate for assessing the strength of slabs supported on their corners by pedestals. A Technical Committee task group has oversight of the slab testing by NCMA which established a center-point load testing method and a proposed acceptance criteria of at least 2,000 lbs before breaking. This breaking load correlates to the 725 psi required for flexural strength in ASTM C1782.

Traffic Calming Research: A consulting firm has been engaged to identify sites and collect data comparing the speed of traffic using interlocking concrete pavements and comparing to similar roads paved with asphalt.

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.
