Methods for measuring technical performance of spreading stress absorbing layer were proposed to guide suitable selection of asphalt binder type and design parameter. Based on the service function analysis of spreading stress absorbing layer, methods for evaluating the anti reflective cracking capability, the shear behavior and the tensile properties were developed. Asphalt rubber stress absorbing layer and SBS modified asphalt stress absorbing layer were then used to evaluate the validity of designed methods. The simplicity and the reliability of the methods as well as the regularity of test data provide the basis for technical evaluation and design parameter determination of spreading stress absorbing layer.
