Abstract
The first process of introducing a theoretical method into the design of asphalt pavement is to set the modulus and Poisson's ratio for each pavement layer. The numerical value gained by it significantly affects the subsequent multilayer elastic analysis. Unlike the temperate regions in Japan, however, cold and snowy Hokkaido has a history of setting unique regional standards of binder penetration, granular grading as well as other properties. In addition, the modulus for each pavement layer in the cold areas in Japan and those in the warm areas tend to be different. In this study, in order to establish a multilayer elastic theory for cold and snowy regions, the modulus for each pavement layer will be examined. This is based on FWD measurement results obtained from pavement testing on the major national roads in Hokkaido. The relationship between the temperature and the modulus of elasticity in an asphalt mixture layer and the range of modulus in granular will be explained.
