    Abstract

    The variations of the Washington degradation test values with particle sizes and times of agitation were studied on some samples of aggregate. The sand equivalent measuring technique was modified to read fines produced. The study has established that the Washington degradation test is a clay leaching test dependent on surface area of charge. Surface attrition also occurs. A mathematical model is proposed which agrees with the samples considered.
