Abstract:
Road engineers have always tried to enhance the tensile strength and rutting resistance of asphalt mixtures, and using various fibers is one way that helps them achieve this objective. Multi-component polymeric fibers consist of ۵ components, two of which, that are quite important, are polymeric and dissolve when bitumen and materials are mixed. This research has used ۰, ۰.۴, ۰.۸ and ۱.۲% multi-component polymeric fibers (by total weight of the mixture) to investigate and compare the performance features of asphalt mixtures containing multi-component polymeric and glass fibers. Results showed that using these fibers had positive effects, prevented main failure and highly improved the low temperature, rutting and stripping performance of asphalt mixtures.
