Development of methods improving storage stability of bitumen modified with ground tire rubber: A review
The following paper presents an overview of methods for improving the storage stability at high temperature of rubber modified bitumen. The storage stability of the rubber modified bitumen can be improved by using a various types of modifiers that form the bonds between the components of these binders. The increase in stability can also be achieved by using crumbrubber surface-activated by furaldehyde or ground tire rubber (GTR) treated by gamma irradiation or modified by devulcanization process. The storage stability of rubber modified bitumen can be also improved by preparing compositions obtained from GTR and other components leading to a reduction in density as compared to unmodified GTR. unmodified GTR.
