Abstract
This study aims to characterise fatigue cracking of two types of waste-derived (bio-oil and LDPE) bitumen. Modified Paris’ law and Griffith criterion were proposed to investigate crack propagation and initiation of the bitumen. Results show that the bio-oil delays and the LDPE accelerates crack initiation, and the bitumen itself dominates crack propagation of unaged bitumen. The bio-oil did not take the effects in altering bitumen’s fatigue performance after pressure ageing vessel (PAV) ageing. PAV-aged LDPE modified bitumen is more prone to fatigue crack in crack initiation phase, but it remains the same crack propagation rate as PAV-aged control bitumen.
