In order to overcome reflective cracks, different techniques have been developed in the past, the most important of which is the use of geosynthetic materials. It has been proven in many studies carried out in this field that using geosynthetics can delay reflective crack initiation and reduce the speed of propagation. In this research, a laboratory simulation was performed on the cracked pavement with five types of geosynthetics. Each type was tested by tensile force. According to the stress… Expand
