Standard Practice for Asphalt Tack Coat Design
standard by American Association of State and Highway Transportation Officials, 2022
Description
This standard determines an application rate for emulsified asphalt or performance-graded (PG) asphalt binder for tack coats.
A tack coat is the application of an emulsified asphalt or performance-graded (PG) asphalt binder, to an existing pavement surface just prior to placement of a pavement overlay course. The tack coat is used to ensure a good bond between an existing asphalt or concrete pavement and a pavement overlay course, between multiple pavement lifts of a structural pavement, and at any vertical surfaces to which a new pavement layer will be placed adjacent, such as curbs, gutters, utilities, and construction joints.
This standard was formerly designated as provisional practice PP 93.
