Abstract:Hot mix asphalt (HMA) pavements are subject to thermal cracking, fatigue cracking, rutting, stripping, raveling, and freeze-thaw damage. Some of these distresses are directly affected by the choice of aggregates. Particle shape, surface texture, particle size, pore structure, and particle strength are the most common characteristics cited for controlling rutting and for maintaining adequate skid resistance. A literature review was conducted to evaluate commonly used and potential test methods for evaluating hot-mix aggregates in terms of pavement performance.
