RISRationality and Applicability of High-Temperature Performance Indexes for Polymer-Modified Asphalts
Publisher: ASCE
Abstract: At present, the rationality and applicability of various high-temperature performance evaluation indexes for polymer-modified asphalts have not been comprehensively explored. This study aimed to fully explore their rationality ...
Performance Characterization of Biorecycled Asphalt and Gray Correlation Analysis between Its Components and Macroproperties
Publisher: ASCE
Abstract: To explore the macroproperties of biorecycled asphalt and the correlation between its components and macroproperties, the cooking-aged waste soybean oil was used as the base oil, along with mixing additives, to prepare the ...
Determination of Minimum Dynamic Modulus (E*) of High Modulus Asphalt Concrete Applied to Semirigid Base Asphalt Pavement
Publisher: ASCE
Abstract: In order to mitigate the serious rutting disease of the semirigid base asphalt pavement (SBAP), measuring the settings of a high modulus asphalt concrete (HMAC) layer in the SBAP structure was proposed in this study. In ...
Exploration for Cohesion and Adhesion Characteristics of High Viscosity–Modified Asphalt: Impacts of Composition-Associated Factors and Thermal Aging
Publisher: ASCE
Abstract: To analyze the impacts of composition-associated factors of high-viscosity asphalt mixtures and thermal aging on the cohesion and adhesion characteristics of high viscosity–modified asphalt (HVMA), neat asphalts (NAs), ...
Composition Design of Waste Vegetable Oil–Based Rejuvenator Based on RSM and Performance Evaluation of Rejuvenated Asphalt
Publisher: ASCE
Abstract: In order to develop an environment-friendly asphalt rejuvenator, waste vegetable oil (WVO) was selected as the base oil. The composition of the rejuvenator was first designed based on the response surface methodology (RSM), ...
Development of Bioregenerant and Its Potential Application: Investigation for Regeneration of RAP Materials
Publisher: American Society of Civil Engineers
Abstract: To achieve efficient utilization of reclaimed asphalt pavement (RAP) materials, a bioregenerant (BR) was developed in this research, and waste vegetable oil (WVO), alkylphenol polyoxyethylene ether (APEO), plasticizer ...
Thermo-Mechanical Responses of a Surface-Coupled AFM Cantilever
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Atomic force microscopy (AFM) has been widely used for measuring mechanical properties of biological specimens such as cells, DNA, and proteins. This is usually done by monitoring deformations ...
Rheological Property Evaluation and Microreaction Mechanism of Rubber Asphalt, Desulfurized Rubber Asphalt, and Their Composites
Publisher: ASCE
Abstract: Desulfurized rubber asphalt (DRA) is a good environmentally friendly road construction material, but its high-temperature performance is relatively insufficient compared to ordinary rubber asphalt (RA). Therefore, in order ...
