Asphalt Pavement Construction | Asphalt Institute

Therefore, an application rate of 0.10 to 0.15 gals/sy of the diluted material will give you the 0.03 to 0.05 gals/sy. Caution #1 : Once the tack coat is applied, time must be allowed for emulsion to break (turn from brown to black) prior to placing hot mix on it.

Tack Coat Application Rate

Diluted emulsions should be applied at a greater rate than undiluted emulsions to obtain the same residual asphalt coverage. Residual asphalt is the asphalt binder left over after the emulsion has set. As you can see, the application rate is doubled in the chart above so the same final residual results from the application.

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.
