In order to study the contact area, pressure distribution and stress concentration distribution on contact region between tire and pavement under different wheel loads and different pavement roughness, the pressure film technology using different specifications of pressure film had been adopted. The results show that the real contact status between tire and pavement is revealed precisely through the pressure film technology. It is convenient to utilize 020060MPa pressure film for the contact area and 050250MPa pressure film for the stress concentration distribution on contact region. The contact areas between tire and pavement with GAC 13C mixture or AC 13 mixture are similar, but less than the contact area between tire and pavement with cement concrete. The stress concentration distribution on contact region between tire and pavement with GAC 13C mixture or AC 13 mixture is apparently more advantageous than that between tire and pavement with cement concrete. Besides, the stress concentration distribution on contact region between tire and pavement with GAC 13C mixture is better than that between tire and pavement with AC 13 mixture.
