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 ...

Abstract: This paper studies the chemo-mechanics of cement beams containing polypropylene (PP) functionalized using ultraviolet (UV) irradiation. It is hypothesized that UV irradiation enhances the load transfer at the interface of ...

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 ...

Abstract: This research project evaluates the low-temperature performance of energy-efficient and environmentally friendly hot-mix asphalt (HMA) paving materials. Innovative materials gaining interest in the asphalt pavement industry ...

Abstract: This paper aims to investigate the viability of using swine waste binder to improve the rheological properties of bituminous asphalt binder. Due to rising bituminous asphalt binder costs, diminishing reserves of crude oil ...

Abstract: The use of reclaimed asphalt pavement (RAP) in neat asphalt mixtures has received significant attention because of its economic and environmental advantages. However, bitumen contained in RAP is severely aged; when RAP is ...
