چکیده

This article is an overview of the new in-place asphalt recycling method and its comparison with the usual methods. The optimization of the existing asphalt layers and surface is significant in many different perspectives including: economic justification, environmental principles and its compatibility with the environment, ergonomic design, reclaiming existing materials and as a result reducing new resource consumption especially the use of quarries and tar. Also the advantages of this method during its application including: the reduction of traffic in the reclaiming areas, the higher speeds of performing this method in comparison to the usual methods, compliance with technical issues such as maintaining alignment with water ducts and sewers andfulfilling the approved quality regulations all prove the necessity of using this method especially in the urban areas. Furthermore, the subject of available technology and how to run them for example: the machinery put to use, additives such as bitumen emulsion and bitumen foam, pavingtechnologies, reclaiming shingles in the damaged layers, how to spread the recycled asphalt, will all be compared with the usual methods of producing new asphalt. It should be noted that the optimization techniques in this method have conformity with the technical and administrative regulations of Iran and international standards of safety and environment and also provides the technical standards of urban areas
