EVALUATION OF VARIOUS SURFACE SEALING TECHNIQUES FOR THE PREVENTATIVE MAINTENANCE OF FLEXIBLE PAVEMENTS. FINAL REPORT

The selection of an appropriate Surface Seal Technique for the preventative maintenance of flexible pavements has been a major concern among the various highway agencies for a number of years. In an effort to better equip the engineer in making decisions concerning the selection of the most cost-effective method of pavement maintenance, seven of the different surface sealing techniques currently available in Florida were constructed in the Fall of 1984 for evaluation. The only major problems encountered at the time of construction were the loss of cover material in the sand seal, mineral seal and surface treatment sections and raveling in the slurry seal section. These problems are believed to have been caused by traffic on the roadway before adequate curing had occurred. The test sections were evaluated immediately after construction and at 6 months, 1 year, 2 years, and 3 years, with the evaluation consisting of rut depth measurements, crack survey dynamic deflection measurements, rideability, and friction testing. At the conclusion of 3 years, the cost-effectiveness of each section was determined.
