29 2024-03: Can we predict the performance and stability of modified bitumen by measuring the viscosity and temperature characteristics?

By measuring viscosity-temperature characteristics, the performance and stability of modified bitumencan be predicted. According to the research results in the reference information, the viscositytemperature characteristics of modified bitumenare different from those of ordinary bitumen,

22 2024-03: Why are the viscosity temperature properties of modified asphalt important for environmental and safety issues?

The viscosity and temperature characteristics of modified asphalt are of great significance to environmental and safety issues, mainly reflected in the following aspects:1. Too high mixing and compaction temperature will cause aging of modified asphalt: According to the research results in the refer

14 2024-03: Is the preparation method of SBS modified bitumen simple? Does its performance meet building and pavement requirements?

According to the description in the reference information, the preparation method of SBS modified bitumenis simple and does not require special equipment. Simply melt and dehydrate the bitumen, add SBS to the bitumenwhile stirring, or add the bitumento SBS, and continue to heat and

08 2024-03: What is the applicability of SBS modified bitumen to different road surfaces at low temperatures?

·According to the experimental results in this paper, SBS modified bitumenhas excellent ductility at low temperature, and the ductility can reach 100 cm at 0℃. It shows that SBS modified bitumencan effectively resist the phenomenon of low temperature embrittlement and has good lo

01 2024-03: How are the properties of SBS modified bitumen affected by the amount of SBS and the dispersion state?

1. The amount of SBS has an effect on the performance of modified bitumen. With the increase of the amount of SBS, the low temperature property, the resilience, the ductility and the rheological property of the modified bitumenare improved. In addition, the increase of SBS dosage also leads to
