What term describes the ability of HMA to provide traction for vehicles?

Answer: A — Skid Resistance

Traction on a pavement surface comes from friction between tires and the roadway, and the term used to describe how well asphalt mixes maintain that friction is skid resistance. In HMA, surface texture—driven by the aggregate’s shape, size distribution, and hardness—and the condition of the asphalt film work together to provide grip, especially in wet conditions where adequate texture helps shed water and maintain contact. Skid resistance is what engineers monitor to gauge how safely the surface will perform during braking and cornering. The other terms refer to materials or production steps rather than the pavement’s ability to grip, so they don’t describe this functional trait.
