Chapter 4: Construction Details, Section 94: Asphaltic

When asphaltic emulsions are used as a tack coat for asphalt concrete, the application rate is specified in terms of a residual rate. The residual rate is the amount of bituminous material that remains on the pavement after water and emulsifying or stabilizing agents evaporate; it is not the application rate from the distributor truck.
