Crumb rubber (CR) from end-of-life tyres has been used for several decades to improve
asphalt mixtures properties. Three main processes of adding CR have been applied to …

Understanding the link between molecular composition and macro-mechanical performance
of asphalt binder is crucial for the selection, modification and performance prediction of …

Terminal blend rubberized asphalt (TB) has attracted wide attention due to its excellent
storage stability and low viscosity characteristics. However, in the special preparation …

In this study, based on the molecular structural analysis of traditional asphalt binder and
polymer modifiers, hydroxyl-terminated polybutadiene (HTPB), which possesses a similar …

The chemo-rheological properties of crumb rubber modified bitumen are always unstable
due to the mutable and uncontrollable swelling-degradation degree of crumb rubber in …

Sustainable bio-oil, as a modifier and partial substitute for asphalt binder, is potentially
reducing dependence on non-renewable petroleum asphalt in pavement engineering …

Polyurethane (PU) modified asphalt has become a hot research topic, but the PU used is
usually synthesized from non-renewable petroleum resources. In this paper, the feasibility of …

High-content rubberized asphalt (HCRA) is a road engineering material with favorable
economic and environmental benefits. However, HCRA is still not widely used due to …

Effects of the chemical fraction on the low temperature rheological behaviours of asphalt
binders were explored in this study. Four fractions, namely saturate, aromatic, resin and …

Under the action of traffic load, the stress and failure state of pavement structure and
materials are complex and diverse. Moreover, pavement materials are multi-phase, multi …
