Abstract

This research presents an assessment of the rheological and anti-aging characteristics of 70# grade asphalts sourced from various manufacturers. By utilizing a range of experimental techniques at both macroscopic and microscopic levels—including gel permeation chromatography (GPC), differential scanning calorimetry (DSC), dynamic shear rheometer (DSR), multi-stress creep recovery (MSCR), linear amplitude scanning (LAS), and bending beam rheometer (BBR) tests—the study investigates the performance of asphalt. Although all five 70# asphalts are classified under the same grade, their performance exhibits significant variation. A direct correlation has been established between microscopic attributes, such as molecular weight distribution and thermal stability, and macroscopic performance, which includes rheological behaviors and anti-aging properties. This study enhances our understanding of the factors influencing asphalt performance and provides guidance for selecting asphalt materials with improved characteristics for highway construction.

期刊介绍： "Rheologica Acta is the official journal of The European Society of Rheology. The aim of the journal is to advance the science of rheology, by publishing high quality peer reviewed articles, invited reviews and peer reviewed short communications. The Scope of Rheologica Acta includes: - Advances in rheometrical and rheo-physical techniques, rheo-optics, microrheology - Rheology of soft matter systems, including polymer melts and solutions, colloidal dispersions, cement, ceramics, glasses, gels, emulsions, surfactant systems, liquid crystals, biomaterials and food. - Rheology of Solids, chemo-rheology - Electro and magnetorheology - Theory of rheology - Non-Newtonian fluid mechanics, complex fluids in microfluidic devices and flow instabilities - Interfacial rheology Rheologica Acta aims to publish papers which represent a substantial advance in the field, mere data reports or incremental work will not be considered. Priority will be given to papers that are methodological in nature and are beneficial to a wide range of material classes. It should also be noted that the list of topics given above is meant to be representative, not exhaustive. The editors welcome feedback on the journal and suggestions for reviews and comments."
