Determining the Stability of Asphalt Concrete at Varying ...

Low stability in asphalt concrete may lead to various types of distress in asphalt pavements (Tigdemir et al., 2002, 2004). The stability of asphalt concrete pavements depends on the stiffness of the mix, bitumen content, softening point of bitumen, viscosity of bitumen, grading of aggregate, construction practice, traffic and climate (Cooper and Pell, 1974).
