Abstract

Asphalt modified with reused rubber from vehicle tires was considered subject to a severe challenge in two directions, the first is the possibility of waste disposal to maintain sustainable infrastructure, and the second is the clear and tangible ability to enhance the characteristics of asphalt mortars and mixes. The need for asphalt cement and mixtures improvement has become unavoidable as a result of the main failure sorts related to the flexible pavement, which are represented by the cracking and rutting, that result from fatigue in the road due to the excessive application of loads and the high tire pressures of vehicles nowadays. The binder may be able to lessen asphalt paving issues and enhance the pavement's overall functionality. Following up on earlier research, it was found that rubber is one of the key components in enhancing the durability and temperature tolerance of modified asphalt cement. The aim of this study is to track the improvement in the rubber-modified asphalt binder as it was observed that the introduction of tire fracture rubber improved the quality of asphalt cement in addition to increasing the cracking factor (G*/Sin), which indicates a greater resistance to cracking. Furthermore, it is believed that the use of rubber crumbs to enhance the properties of asphalt cement will improve the sustainability of asphalt pavement economically and environmentally.
