Title: Impacts of Structural Parameters Change on Asphalt Pavement Deflection
Abstract: Asphalt pavement structure and changing range of structural parameters is definite. Based on the theory of multi-layer elastic system, influence law that the change of subgrade resilient modulus, semi-rigid base resilient modulus, surface resilient modulus, base thickness and surface thickness impact on road surface deflection is determined through software of BISAR3. 0. Road surface deflection is mainly from subgrade resilient modulus. The combination of subgrade resilient modulus and semi-rigid base thickness is bigger influence than the combination of the other cases. The most unfavorable combination design of asphalt pavement structure layer is proposed. These conclusions have an important guidance significance for asphalt pavement design.
