Low Temperature Mechanical Properties of Asphalt Concrete
At low temperatures, asphalt concrete becomes stiffer, stronger (higher modulus/intensity), but more brittle, leading to reduced failure strain and increased risk of thermal cracking as restrained shrinkage creates tensile stress. Key mechanical properties shift from viscoelastic to more elastic/brittle behavior, with significant temperature sensitivity below certain thresholds (e.g., 15.4°C), affecting dynamic modulus, fracture toughness, and susceptibility to cracking, influenced by binder type and air voids.
