Determination of Rejuvenator Proportion within the Recycled Bitumen: Empirical Double-Logarithmic Formula and Calibration
Publisher: ASCE
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 ...
Sustainable Utilization of Recycled Waste in High-Viscosity Asphalt Binders: Case for Improvement in Aging Resistance
Publisher: ASCE
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 ...
Performance Characterization of Warm-Mix Asphalt Containing High Reclaimed-Asphalt Pavement with Bio-Oil Rejuvenator
Publisher: ASCE
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, ...
Stabilization of Coarse Aggregates with Traditional and Nontraditional Additives
Publisher: ASCE
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 ...
