Abstract:
In order to analyze the changes of joint opening displacement ( JOD) of cement concrete pavemen!under different road structures and material parameters, the joint model was established by using a 3D finiteelement method, Various factors of JOD were quantitatively analyzed, The results show that JOD is significantly effected by temperature gradient, base modulus, slab length and slab thickness, and the relationship be.tween JOD and temperature gradient is the logarithmic, the base modulus is the power, and both the slablength and thickness are the exponential. Based on the above analysis, the formulae of joint changes have beenset up with the consideration of four main factors, the theoretical analysis is verified by using the measured da.ta, and the results provide the potential for the joint design and selecting the joint filler.
