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.

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

Future Research Planning for Segmental Concrete Pavements: A focus group was assembled to bring together representatives from academia, the private sector, government agencies, industry, and Concrete Masonry and Hardscapes Association (CMHA) staff. With David K. Hein, P.Eng. as the facilitator, this group concentrated on various concrete pavement solutions, including conventional and permeable interlocking concrete pavement (PICP), concrete paving slabs, concrete planks, and concrete grids.

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.

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.

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.
