Effect of aged crumb rubber bitumen on performance dense graded mix in Malaysia
To prevent pavement failure there are different solutions such as adopting new mix methods or utilization of waste materials as additives. The main objective of this study is to evaluate the effect of crumb rubber (CR) added to bitumen binder as a reinforcing material on dense graded asphalt (DGA) m...
