SURFACE TREATED PAVEMENT AND METHODS FOR TREATING PAVEMENT SURFACES TO IMPROVE CHIP RETENTION

摘要

Surface treated pavement and methods for treating pavement surfaces are provided herein. A method is also provided for treating pavement to improve chip retention. The method includes contacting a surface of the pavement with a bitumen emulsion containing an adhesion modifier to form a layer of bitumen emulsion. Aggregate is applied on the layer of bitumen emulsion. The adhesion modifier includes at least one polymer having a carboxylic acid and/or anhydride functional group, such as oxidized high density polyethylene.
