Maintaining Flexible Pavements - The Long-Term Pavement Performance Experiment SPS-3 5-year Data Analysis

Research/Reference: useful for researchers doing further work in the pavement area as well as those developing improved testing and design procedures. Includes documents of historical value.

Primary Topic: Flexible Pavement

Description: The Strategic Highway Research Program developed and coordinated construction of test sections for flexible pavement maintenance throughout the United States and Canada. Test sites included specific test sections for evaluation of the performance of crack sealing, slurry seals, chip seals, and thin hot-mix overlays as maintenance treatments. Each site also included an untreated control section.

This report discusses the project background and analysis of monitoring data collected over a 5-year period by the Long-Term Pavement Performance project at SPS-3 sites throughout the United States and Canada. The analysis considers three important characteristics of the maintenance treatments: treatment performance, timing of application, and cost-effectiveness. In addition to data analysis results, the report conclusions include information from "Pavement Treatment Effectiveness, 1995 SPS-3 and SPS-4 Site Evaluations, National Report" May 1997.
