Abstract: Rejuvenators as environmentally-friendly materials can restore the properties of aged bitumen physically or chemically. A proper dosage of a rejuvenator can achieve the desired properties of bitumen. Thus, this study ...

Abstract: High-viscosity asphalt binder is a key material for porous asphalt pavement, but its susceptibility to aging limits its applications. Three recycled-based high-viscosity binders (RHBs), including RH-1, RH-2, and RH-3, were ...

Abstract: Warm-mix asphalt (WMA) technology and recycling of asphalt pavement, i.e., reclaimed asphalt pavement (RAP), have been becoming more popular in recent years due to their economic and environmental benefits. Similarly, ...

Abstract: High-quality coarse aggregates are routinely used for the surface, base, and subbase layers in paved roads or the surface course in unpaved low-volume roads. Unfortunately, high-quality aggregates meeting stringent material ...
