Title: A STUDY ON TEMPERATURE DEPENDENT MODULUS FOR ASPHALT CONCRETE
Abstract: The structural capacity of flexible pavements is greatly influenced by the stiffness of the asphalt concrete layer. The asphalt layer stiffness is a function of temperature and changes every hour through a year. The relationship between the stiffness of asphalt layer and its mean temperature has been presented in the exponential form. In this paper, an asphalt layer is broken into thinner layers and assigning temperature to these layers by using the conventional model. Then the parameters in the type model are determined by matching the surface deflections with FWD deflection bowl.
