a quick review of construction another FAA grade seal coat (GSB-88) was provided as an option. The GSB-88 has been used the past two summers with good results. The product is proposed to both seal the pavement and rejuvenate the older asphalt. Chip SealA cape seal is an application of a chip seal followed by a slurry seal. The term "cape" is derived from Cape Province of South Africa where this process was developed. A chip seal is applied to the road,

As soon as the liquid asphalt meets the road surfaceEvaluation of Asphalt Rubber and Reclaimed Tire Rubber in Chip Seal Applications. The objective of this study is to improve the durability and to extend the life of chip seal applications in Louisiana using rubber-modified emulsion and reclaimed rubber tires in the aggregate layer.This study investigated the laboratory performance of basalt fiber (BF) used as an asphalt-chip seal. Specimens of the basalt fiber asphalt-chip seal (BFACS) at various contents of styrene–butadiene–rubber (SBR)-modified emulsified asphalt (EA) and BF were prepared. These were subjected to a series of tests,
