14. ABSTRACT
Hot-mix asphalt (HMA) pavements are subject to thermal cracking, fatigue cracking, rutting, stripping, raveling, and
freezethaw 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 poten-
tial test methods for evaluating hot-mix aggregates in term of pavement performance.
