Cement emulsified asphalt composite material (CA cement) has the excellent properties of cement and cement. As a cementing material, concrete can be one choices road paving materials. However, under effect temperature wheel load, performance it may get worse; especially, creep behavior CA an important influence on stability pavement structure. This paper mainly focuses research recovery cement, determines raw materials proportions formulates experimental programs such as tests stress...
Enlarging local raw material utilization and reducing project costs is a new trend in the construction field. Under this background, sandstone was utilized cement‐stabilized base study. The mineral composition of proportion each parent rock were analyzed using X‐ray diffraction. To verify its feasibility, sandstone, syenite, marble, basalt aggregates selected to test mechanical properties road performance four aggregate concretes at 7, 28, 90, 180 days. results showed that although slump...
In order to reuse waste resources (waste engine oil and asphalt mixture), the regeneration process of on aged is systematically explained. The BA was treated by aging test, basic mechanical properties, molecular dynamics simulation, infrared spectrum test were carried out this basis. results showed that WEO can restore physical properties asphalt, recommended amount 3%. density model corresponds actual situation asphalt. components are more aggregated. After added, aggregation reduced...
Asphalt pavement hot recycling technology can improve resource utilization efficiency, reduce energy waste and CO2 emissions, bring huge economic social benefits, further promoting the realization of “carbon peak carbon neutrality”. This paper uses single logarithmic regression fitting on fatigue failure life recycled asphalt mixture with high RAP content to characterize influence (R), stress ratio (C), loading frequency (H) test temperature (T) mixture. Subsequently, relationship between...
A stabilized rubber powder-modified asphalt was provided for the field of asphalt, and optimal blending amount stable powder determined from indicators, such as penetration, penetration index, ductility, softening point, viscosity at 135 °C. The viscoelastic curve measured, thermal storage stability test showed that has significant stability. specific surface area, scanning electron microscope, differential calorimeters were used to analyze dispersion state aggregation particles in etc....
Desulfurized rubber powder and SBS were used as asphalt modifiers to study the rheological properties performance of desulfurized powder/SBS composite-modified (DR/SBSCMA). First, basic indicators such penetration, ductility, softening point, viscosity studied. Second, high-temperature low-temperature evaluated by using a dynamic shear rheometer (DSR) bending beam (BBR). Finally, their stability, crack resistance, water stability under gradation AC-13 SMA-13 evaluated. The results show that...
