Abstract:The need for an aggregate abrasion test which effectively differentiates between the quality of aggregates of various unit weights prompted the development of a new test apparatus. The method selected uses air-driven sand as the abrading mechanism. Research findings based on tests of five natural and forty-seven synthetic aggregates tentatively indicate that the sandblast test is statistically reproducible and is characterized by improved differentiation between various aggregates when compared to results obtained with the Los Angeles test, ASTM C 131.
