Performance Evaluation of Thermosetting and Thermoplastic Polyurethane Asphalt Mixtures
Publisher: ASCE
Abstract: Polyurethane (PU) asphalt binders have been proved to be a promising class of paving materials for steel bridge deck or highway road. This study further evaluated the performance of a thermosetting-PU (TS-PU) asphalt mixture ...
Laboratory Investigation of PPG-TDI Polyurethane–Modified Asphalt Binders and Mixtures
Publisher: ASCE
Abstract: Considering the defects of insufficient low-temperature flexibility and high cost of epoxy asphalt binder, low-cost polypropylene glycol (PPG) and toluene diisocyanate (TDI) were used to synthesize two polyurethane (PU) ...
Laboratory Study and Molecular Dynamics Simulation of High- and Low-Temperature Properties of Polyurethane-Modified Asphalt
Publisher: ASCE
Abstract: This study investigated the modification mechanism of polyurethane (PU) on the high- and low-temperature properties of asphalt based on experimental and molecular dynamics (MD) simulations. PU-modified asphalt was prepared ...
Investigation on the High- and Low-Temperature Performance of Organic Rectorite and Polyurethane Composite-Modified Asphalt Binder
Publisher: ASCE
Abstract: Organic rectorite (OREC) can significantly improve the resistance of asphalt to deformation and aging, but it tends to cause low-temperature cracking. To solve this defect, a novel idea that develops an OREC and polyurethane ...
