Fire-Retarding Asphalt Pavement for Urban Road Tunnels
A State-of-the-Art Review and Beyond
With the rapid urbanization and development of metropolises, urban road tunnels have been constructed at an increasing rate, significantly alleviating urban traffic pressure, and improving urban resilience. Fire hazards have become a major threat to modern road tunnels due to ...

Polycyclic Aromatic Hydrocarbons (PAHs) in asphalt materials is a type of serious environmental hazard, and the main pollution resource in road engineering. Aiming at the requirement of PAHs rapid detection method in asphalt pavement construction for low environmental hazard, ...
Rubberized asphaltic materials have been frequently combined with warm-mix asphalt technologies to tackle the issues of high energy consumptions and emissions during construction. Effective and accurate characterization of binder properties is conducive to the improvement of l ...
From the pavement construction emission perspective, bitumen emulsion is considered more environment-friendly than conventional bitumen because of its much lower construction temperature. However, bitumen emulsion faces the major concern of low mechanical strength especially a ...
Crumb rubber modified bitumen (CRMB) can be regarded as a binary composite system in which swollen rubber particles are embedded in the bitumen matrix. The current study aims to further improve the prediction accuracy of micromechanical models for CRMB by considering the inter ...
