In order to analyze the changes of joint opening displacement(JOD) for cement concrete pavement under different road structures and material parameters, the joint model is derived and presented. The model takes into account conservation of various factors, the results have shown that JOD is significantly effected by temperature gradient, base modulus, slab length and slab thickness, and then the formula of joint changes have been set up with the consideration of four main factors. According to theoretical results, three different base types about lean concrete, cement stabilized macadam and graded broken stone have on-site observation of JOD for one year in Guangxi, and the above formula is verified, which provides the potential for the joint design and selecting the joint filler.
