and Implementation of a Polymer Asphalt through Pavement

heavy polymer modified asphalt binder (5-7). The current cost of PG 82-22 asphalt binder is approximately $100/liquid metric ton more than PG 76-22 asphalt binder and $250/liquid metric ton more than unmodified PG 67-22 asphalt binder. Prior to implementation, the benefits of a PG 82-22 asphalt binder should be better quantified to justify its use.

Evaluation of Bond Strength Between Paving Layers for Hot ...

Once the base course is treated with prime coat, the surface course is constructed. The surface course may consist of multiple layers, including (a) wearing course (b) binder course and (c) asphalt base. To achieve a good bonding between the lifts of the surface course, tack coat is applied. Tack coat is a thin bituminous asphalt layer, and is ...

Design and Performance of Anticracking Asphalt-Treated Base

To enhance the crack resistance of asphalt-treated base (ATB), a type of gapped and semiopened gradation ATB mixture, GSOG, was designed. Its design method was proposed based on the volume design method and performance tests. Firstly, several gradations were designed preliminarily in which middle particle sizes of coarse aggregates were partially or completely gapped according to the
