Resistance to abrasion of crushed stone by use of the Los Angeles machine, obtained in accordance with the designations of JIS and ASTM, diverges by gradings of test samples, even their original rocks are same, owing to variation of weight of the samples, number of steel spheres and number of revolutions. Measurement of the abrasion of the crushed stone, therefore, should be performed fixing the grading and weight of the test samples the weight of steel spheres and the number of revolutions of the Los Angels machine. Accordingly the authors have investigated the influence of these test conditions on the abrasion of the crushed stone, in order to obtain data for optimum test conditions.
