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...
Collapsible loess soils are widely distributed in semiarid and arid regions. The eroded landforms formed by the unique collapsibility of may cause environmental damage that puts lives property at risk. In this work, collapse potential, quantitative analyses, qualitative characterization microstructures samples were investigated using double oedometer tests, scanning electron microscopy (SEM), digital image analysis method to probe fundamental mechanisms collapsibility. A large number field...
The purpose of establishing a tailings dam is to safely store protect the natural environment from damage. Accidents at dams are frequent, however, with serious consequences not only threats life and property but also pollution environment. Many accidents caused by seepage failure. In this paper, object case study Lixi dam. Three- two-dimensional finite element models established. field project under different working conditions simulated position phreatic line obtained. safety factors...
Realizing high electroluminescence dissymmetric factor and external quantum efficiency at the same time is challenging in light-emitting diodes with direct circularly polarized emission. Here, we show that can be simultaneously achieved based on chiral perovskite dots. Specifically, dots chiral-induced spin selectivity concurrently serve as localized radiative recombination centers of spin-polarized carriers for emission, thereby suppressing relaxation spins, Meanwhile, improving ligand...
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....
Longitudinal cracking is one of the most important distresses asphalt pavement in permafrost regions.

Some computer aided engineering (CAE) simulation techniques, such as...
Incorporating reclaimed asphalt pavement (RAP) into mixtures achieves astonishingly environmental and economic benefits. However, there is hesitation to use higher RAP content due the concern regarding deterioration in performance, especially cracking resistance. Basalt fiber has been considered an effective additive reinforce performance of and, subsequently, reinforcement effect also expected for high-RAP mixtures. Therefore, this study investigated basalt on with 0%, 30%, 40%, 50%...
