ABSTRACT
Approximately 95% of the world's roadways are made of flexible pavements traditionally bound with bitumen. Modern roads must use the least amount of energy and raw materials for sustainable environmental development. Asphalt polymer technology can solve this issue using bio-binders and rubber waste, such as old tires, to enhance road infrastructure. Because crumb rubber can improve the mechanical and functional performance of mixtures, its use in asphalt paving has gained popularity. In addition, other renewable rubbers, such as liquid natural rubber (called latex) and solid natural rubber, can be used. Natural rubber is an elastomer used to repair concrete and asphalt. The mechanical characteristics of rubber asphalt, created by blending solid natural rubber, asphalt, and crumb rubber in a specific ratio, were examined in this study. Rheological testing with a dynamic shear rheometer was used to study the mechanistic behavior of rubber asphalt. The rubber combination utilized had an asphalt composition of 7% and 10% by weight and a crumb rubber to solid natural rubber weight ratio of 65:35. The results indicated that the asphalt stiffness modulus increased from 157.08% to 189.55% when combining crumb and solid natural rubber. Moreover, Superpave specifications state that using a mixture of solid natural and crumb rubber can increase rutting resistance and fatigue resistance at high temperatures.
