The effect of polymers and epoxy resin on properties of asphalt were evaluated. Rheological properties of mixtures were measured and the stress-strain relationships in model pavements were analyzed. Mixtures with high viscosity asphalt showed high strength, high modulus and high dynamic stability, and showed a consequent high deformation resistance to wheel load and low tensile strain in the surface on a model steel plate deck. The failure envelope concept was introduced to find the temperature at which thermal cracking was induced in the surface of pavement; mixtures with low viscosity asphalt showed lower thermal cracking temperature. Relaxation moduli and shift factors obtained from various test methods were similar to each other, and were similar at the specific temperature for each mixture.
