Introducing a Sustainable Bio-Based Polyurethane to Enhance the Healing Capacity of Bitumen
Publisher: ASCE
Abstract: This paper introduces the in-situ formation of biomodified polyurethane in bitumen as a novel strategy to enhance the healing capacity and aging resistance of bitumen. Bitumen is a substance that is known to have the ...
Advancing Crack Resistance and Environmental Sustainability in Asphalt: Investigating Recycled Cigarette Filters in Stone Matrix Asphalt
Publisher: American Society of Civil Engineers
Abstract: The disposal of cigarette filters (CFs), primarily composed of cellulose acetate fibers and containing harmful substances like burned tobacco, tar, and heavy metals, poses a significant environmental threat due to their ...
Biobased Polyurethane: A Sustainable Asphalt Modifier with Improved Moisture Resistance
Publisher: ASCE
Abstract: This paper evaluated the effect of a biobased polyurethane modifier on the moisture resistance of asphalt binder. Biomodifiers with high acid values have been implicated in moisture damage to asphalt. Here, castor oil with ...
