- Description
- High modulus asphalt binder (HMAB) has excellent rutting resistance but it might have premature cracking concerns due to its high stiffness. In this study, the intermediate temperature fracture performance of six HMABs was evaluated from a rheological and mechanical standpoint. The linear amplitude sweep (LAS) test, Glover-Rowe (G-R) parameter, and pure linear amplitude sweep (PLAS) test were employed for the rheological characterization, while the binder fracture energy (BFE) test and the double-edge notched tensile (DENT) test were implemented to investigate mechanical performance. The results show that HMABs have lower cracking resistance than conventional asphalt binders, and this was due to the insufficient ductility of their internal polymer networks. Of the five test methods, the PLAS, BFE, and DENT tests are highly recommended for evaluating the cracking resistance of HMABs at intermediate temperatures. 2022 Elsevier Ltd
