Abstract
Thermoplastic elastomers (TPEs) based on ground tire rubbers (GTRs) and polyethylene were used for asphalt modification. TPEs were prepared by dynamic devulcanization (DD) in the presence of desulfurizer and dynamic vulcanization (DV) with sulfur, respectively. Structure and properties of TPEs and their modified asphalts were characterized by morphology, thermal, sol-gel content and mechanical testing. It was found that DD process decreased the physical properties, while the DV process strengthened that of TPE. The results also showed that the compatibility between PE and GTR was improved by DV, which further enhanced physical property and stabilized the TPE in the asphalt.
