Numerical Simulation of Indirect Tensile Test Based on the Microstructure of Asphalt Mixture
Publisher: American Society of Civil Engineers
Abstract: Indirect tensile (IDT) test is widely adopted to evaluate the anticracking performance of hot-mixture asphalt (HMA) at intermediate and low temperatures. This paper presented an approach to simulate the IDT test based on ...
Rheological Properties and Mechanism of Asphalt Modified with Polypropylene and Graphene and Carbon Black Composites
Publisher: ASCE
Abstract: The application of polypropylene (PP) to asphalt pavement construction, as one of the measures to dispose white waste, has suffered from many challenges. Meanwhile, the emerging nanomaterials for asphalt pavements has ...
Preparation Process and Performance of Polyurethane-Modified Bitumen for Ultrathin Asphalt Layers
Publisher: ASCE
Abstract: To adapt to the high temperatures in the summer and resist the shrinkage effect caused by high-temperature differences, this study developed an asphalt material with excellent high-temperature stability and applied it to ...
Effects of Physio-Chemical Factors on Asphalt Aging Behavior
Publisher: American Society of Civil Engineers
Abstract: Based on an accelerated asphalt-aging test in the laboratory, the authors evaluated the physical and chemical properties of asphalt at different aging times and temperatures for this paper. They evaluated the properties ...
Synthesis and Characterization of Calcium Alginate Capsules Encapsulating Soybean Oil for In Situ Rejuvenation of Aged Asphalt
Publisher: ASCE
Abstract: Asphalt aging is a major cause of distresses in asphalt pavement, seriously decreasing the in-service performance and shortening the lifetime of pavement. Traditional asphalt rejuvenating methods usually consume a great ...
