Primary Topic: Pavement Maintenance
Description: The SPS-3 and SPS-4 experiments were constructed in 1990 under the Strategic Highway Research Program (SHRP) to evaluate the effectiveness of and to determine the optimum timing for applying preventive maintenance treatments for flexible and rigid pavements. Documentation of conclusions from recent field reviews to evaluate the performance of the maintenance treatments is presented. The opinions of State Expert Task Groups (ETG's) on each of four Long-Term Pavement Performance (LTPP) regional reviews are reported, along with a summary of data compiled by these ETG's to quantify the level of the treatment performance. One tour was conducted in each LTPP region for this purpose.
Each LTPP regional ETG developed a report summarizing their observations. The final report, Pavement Treatment Effectiveness, 1995 SPS- 3 and SPS-4 Site Evaluations, National Report, combines the findings of all four regional groups.
