Abstract
Mechanical behaviors of bonding between concrete and asphalt layers and the mechanical parameters of the asphalt are important for the analysis of whitetopping. In this study, we constructed the whitetopping, conducted loading test and measured the strains in the concrete and asphalt layers. Through comparing the measured and analyzed strains, we obtained the spring coefficient of the element between the concrete and asphalt layers and the elastic moduli of the asphalt layers. The results show that the spring coefficient is different for each position of the slab and the elastic moduli of asphalt layers are almost the same as those computed by McLeod's nomograph. As the results, the mechanical parametersin the analytical model have been proposed.
