Abstract :
    The phenomenon of permanent deformation is one of the many defects found in flexible pavement. In addition to destroying the transport infrastructure, this failure will bring financial losses to users. It is commonly used to correct this defect of hot asphalt. Since the phenomenon of permanent deformation is abundant in most hot areas because of the thermal absorption of asphalt and is considered as a disruption to the surface, there are practically no problems with the structure of the road. Therefore, it requires a proper method to reduce the cost of repair and restoration and impose less risks. Hence, by studying the applied research method, the effect of recycled asphalt with on-site cold recycling method was studied in reducing costs and reducing environmental damage, And the results were that cold recycled asphalt reduced the cost of repairs by reducing the cost of transportation and decoupage, non-use of heat in the mix, the lack of needed new materials and the use of existing materials, On the other hand, by not using heat to treat and reuse existing materials, which reduces the transfer of materials to waste cemeteries, it reduces environmental risks and prevents damage to the environment.
