Evaluation of Tests for Toughness/Abrasion Resistance and Durability/Soundness of Coarse Aggregates



Many tests have been developed to empirically characterize aggregate without necessarily strong relationships with the performance of final products incorporating these aggregates. This seems to be particularly true for “toughness and abrasion resistance” and “durability and soundness.” Toughness/abrasion resistance and durability/soundness of aggregate are correlated, but represent resistance to degradation when subject to mechanical forces and weathering, respectively. A literature review identified five toughness/abrasion resistance and four durability/soundness test procedures. Sixteen aggregates with a wide range of properties were tested with eight of the identified test procedures. Results from the tests and test precisions were compared.
