Enhancement of Road Construction by Using Recycled Tire Rubber Modified Bitumen

Abstract

Conventional asphalt used in road construction in Albania has faced many problems due to its lower quality and lack of maintenance. Most of the problems come from urban and industrial cities where vehicle usage is very high. The problem has been faced in the first three years after their construction with conventional asphalt due to lower crack resistance and skid resistance. This emerging situation has sparked recent interest from different researchers, companies, and the Albanian government to support improving the quality of road construction. Our research work will be focused on the production of mixture asphalts by using recycled tire rubber modified bitumen (RTR-MBs). Moreover, it will be analysed the physical and mechanical tests, which involve, respectively, penetration tests, softening point tests, and Marshall tests. All the new results will be compared to conventional asphalt.
