During the conduct of Strategic Highway Research Programs (SHRP) on highway operations, flexible and rigid pavement preventive maintenance treatments were placed on pavements in the United States and Canada. The placement and performance monitoring of these Specific Pavement Studies (SPS-3 and SPS-4) has been conducted under the SHRP and Federal Highway Administration (FHWA) Long-Term Pavement Performance Program (LTPP).
Field performance reviews of the preventive maintenance treatments have also been conducted by Expert Task Groups (ETG) organized by the Pavement Division of the FHWA. The ETG performance surveys conducted after 5 years of service are summarized in this report and are intended to provide early performance information and guidance to public agencies utilizing preventive maintenance techniques.
This report is prepared as part of an FHWA-sponsored study titled Pavement Maintenance Effectiveness on SHRP Experimental Pavement Sections and 'conducted for the Long-Term Pavement Performance and Pavement Divisions of the FHWA. The final report for the study will be available in early 1997.
