A LABORATORY TEST TO EVALUATE THE SHAPE AND SURFACE TEXTURE OF FINE AGGREGATE PARTICLES

RECENTLY A SIMPLE TEST FOR EVALUATING THE ANGULARITY AND TEXTURE OF SANDS HAS BEEN DEVELOPED IN THE LABORATORIES OF THE BUREAU OF PUBLIC ROADS. THIS TEST IS BASED ON THE PRINCIPLE THAT SMOOTH-TEXTURED ROUNDED SAND PARTICLES OFFER LESS RESISTANCE TO FREE FLOW THAN DO ROUGH TEXTURED ANGULAR PARTICLES. IT IS BELIEVED THAT THIS TEST WILL BE OF VALUE IN LABORATORY STUDIES OF BITUMINOUS MIXTURES AND IN EVALUATING THE SURFACE CHARACTERISTICS OF SANDS IN THE FIELD WITH RESPECT TO SPECIFIED REQUIREMENTS. THE EQUIPMENT IS SIMPLE, THE OPERATION IS PRACTICALLY FREE FROM THE PERSONAL ELEMENT, AND THE RESULTS OBTAINED BY DIFFERENT OPERATORS ARE HIGHLY REPRODUCIBLE.
