Due to an asphalt plant expansion and reduced availability of the TRMSS in year five of the program (2017), 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 Seal

A 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, then the excess aggregate is removed after the asphalt has cured. The slurry is then applied over the chip seal treatment.

Crumb rubber R18 modified binder (CRR18MB), which contains a minimum 18% crumb rubber and is blended at a refinery terminal, is a relatively new hot-applied asphalt binder for chip seals. This binder meets Caltrans PG 76-22R specifications. The asphalt rubber binder and the CRR18MB are applied at high temperatures, generally above 340°F.

After construction of chip seal layer an asphalt overlay is applied on the chip seal layer. The function of this underseal is to waterproof the existing pavement and retard reflective cracking. This application is also known as SAMI (Stress Absorbing Membrane Interlayer). (3) Hot Mix: Asphalt rubber is used as the binder for hot mix. (4)

The cost of chip seals is 15%-20% of the cost of pavement overlays. The Chip Seal Process. First, asphalt is mixed with about 30% water. This emulsified mixture is then applied to the road using a special spray truck. As soon as the liquid asphalt meets the road surface, the water starts to evaporate.

Abstract. The asphalt rubber blend design is an empirical procedure and is quite sensitive to the variability of the components properties. A better understanding of the physical phenomenon involved during the curing process is a pre-requisite step to propose a rational design procedure.
