During the conduct of the Strategic Highway Research Program (SHRP) on highway operations, rigid pavement, preventative maintenance treatments were placed on pavements throughout the United States. The placement and performance monitoring of these Specific Pavement Study (SPS)-4 projects have been conducted under the SHRP and Federal Highway Administration (FHW A) Long-Term Pavement Performance (LTPP) program. The information derived from this study will contribute greatly toward advancing the state of the practice of joint sealing and resealing of portland cement concrete (PCC) pavements.

This report provides information to pavement engineers and maintenance personnel on the results of the SPS-4 joint seal experiment. It presents the performance and cost data of various joint sealant materials, and procedures for sealing joints in PCC pavements.

This report will be of interest to anyone concerned with the maintenance and rehabilitation of PCC pavements.
