    Abstract

    The degradation test method herein described is designed to measure the quantity and quality of the material produced by attrition similar to that produced in the roadway under repeated traffic loading and unloading. The quantity is indicated by a percentage by weight of fine material produced. The quality is measured by means of a modified sand equivalent test. The fine material is made by the rubbing action of one particle against another in the presence of water by means of air jets.
