The demand for bituminous materials is continuously growing; crude oil-based asphalt binders are non-renewable, and facing rapid depletion. With the increase of petroleum-based prices, seeking an alternative, renewable material such as bio-asphalt has become a hot research topic. However, shortcomings in this area have been identified, notably concerning high-temperature performance at present. This aims to comprehensively apply conventional tests to, study rheological behavior of,...
To uniform the evaluation indicators of Styrene-Butadiene-Styrene (SBS) modified asphalt, SK70# and SK90# matrix asphalt were by different SBS modifier dosage in this study. The test methods China Superpave used to performance each SBS-modified respectively, from which appropriate index was determined. results showed that addition improved high temperature lowered sensitivity binder, while it increased viscosity binder temperatures. Due variability appeared penetration swelling not...
Macroperformance, i.e., skid resistance, high-temperature, and compaction performance, are related to the functional safety, durability of asphalt pavement. Currently, research on such influencing factors focuses properties asphalt, gradation composition, pavement structure, so forth, whereas geometrical characteristics coarse aggregate, especially its angularity, has not gained due attention from researchers. This paper investigated effects coarse-aggregate angularity high-temperature...
Fatigue damage is a notable distress of asphalt pavements. However, monitoring the development process such distresses in real-time remained challenges for researchers. In this paper, self-developed sensing facility has been utilized to obtain aggregate kinematic response semi-circular specimen during fatigue loading upper-middle (H/2), lower-middle (L/2) and lower-right (L/3) positions specimen. Angle acceleration variation X, Y, Z directions were analysed independently at three positions....
Developing new sustainable materials such as bioasphalt has become a research trend in recent years. In this study, modified with the addition of styrene-butadiene-styrene (SBS) was investigated to whether it can replace petroleum asphalt binder 50 penetration grade (50#) road performance at lower price. A series laboratory tests were carried out evaluate SBS-modified binders and mixtures, including penetration, softening point, ductility, rutting, moisture susceptibility, low-temperature...
