The continues between the slabs is reduced by creating a joint in concrete pavements to control the contraction and expansion curves and the execution and This continues is controlled by sewing and tie bar and dowel bar. These joint are critical points in concrete pavements, By applying the loads, the deformation of the slabs and finally the stress and failure in the concrete pavement. These joint also have exploitation problems and economic problems in the repair and maintenance of concrete pavements. This research is field-based and in software In Concrete pavement done And observation in slabs with smaller dimensions according to the number and location of joint , It has more critical points than bigger slabs. As these critical points increase, pavements are more vulnerable to malfunction and cause problems in operation. Damage caused by traffic in critical areas and at the joint and in the path of the wheels is more than that. The cause of the problem is due to the simultaneous combination of loading and deformation of the slab under loads due to temperature difference and traffic flow crossings. If you use a concrete pavement with slabs of larger dimensions, comfortable, economic life, and more safety in roads and airports, and in other concrete pavements.
