RISAsphalt Binders Blended with a High Percentage of Biobinders: Aging Mechanism Using FTIR and Rheology
Publisher: American Society of Civil Engineers
Abstract: The objective of this study is to characterize the rheological properties and aging mechanism of asphalt binders blended with high percentages of biobinders using Fourier transform infrared spectroscopy (FTIR). The petroleum ...
Postprocessing Method for Dynamic Modulus Tests of Hot-Mix Asphalt
Publisher: American Society of Civil Engineers
Abstract: The main objectives of this study are: (1) to develop a postprocessing method for analyzing the dynamic modulus test of compacted asphalt mixtures; (2) to identify optimum regression equations for the compressive stress ...
Evaluation of Low-Temperature Binder Properties of Warm-Mix Asphalt, Extracted and Recovered RAP and RAS, and Bioasphalt
Publisher: American Society of Civil Engineers
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 ...
Aging Influence on Rheology Properties of Petroleum-Based Asphalt Modified with Biobinder
Publisher: American Society of Civil Engineers
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 ...
