What is Scrap Rubber in Asphalt Pavements about?

This document summarizes research on using scrap rubber in asphalt pavement surfaces. It describes developing two mix designs incorporating scrap rubber: (1) a "PlusRide" gap-graded mix and (2) a "Chunk Rubber Asphalt Concrete" mix. It evaluates the mixes through laboratory testing of strength, stiffness, creep resistance, and effects of aging. Preliminary wheel tracking tests showed scrap rubber mixes had lower rolling resistance than conventional asphalt, with potential benefits for fuel economy. Overall,
