Aggregate Toughness/Abrasion Resistance and Durability

Toughness/abrasion resistance and durability/soundness tests for characterizing aggregate used in asphalt concrete were identified and evaluated, and those test methods that best correlate with field performance were determined. Based on a review of literature and specifications, laboratory tests for characterizing aggregate toughness/abrasion resistance and durability/soundness were selected. Sixteen aggregate

EVALUATION OF TESTS FOR TOUGHNESS/ABRASION

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. The Los Angeles abrasion

2 Toughness & Abrasion Resistance • AASHTO T96, ASTM C131 • Needs to resist degradation when stockpiled. • Must be tough and resist crushing and degradation when HMA is produced and compacted. • Must resist abrasion and polishing due to traffic loading. Otherwise, skid resistance will become a problem. • Must have the ability to transfer loads to the underlying layers.

Toughness and Abrasion Resistance Pavement Interactive

Toughness and Abrasion Resistance Aggregates undergo substantial wear and tear throughout their life. In general, they should be hard and tough enough to resist crushing, degradation and disintegration from any associated activities including manufacturing, stockpiling, production, placing, compaction (in the case of HMA) and consolidation (in the case of PCC) (Roberts et al., 1996 [1] ).
