Chapter 4: Binder and Aggregate Application Rates

The design method described in this section is based on a modification of the original Kearby method and was first recommended to TxDOT by Texas Transportation Institute in 1981 (Epps et al., 1981). It is still the method most commonly used by TxDOT today. A formal design method such as this can effectively serve to guide inexperienced personnel through the “art” of seal coat design and to train personnel including inspectors, designers, and laboratory personnel. Correction factors for binder ap
