17 2025-03: How to optimize the viscosity and strength of rubber bitumen by adjusting parameters?

In the production process of rubber bitumen, by adjusting parameters such as temperature and time, its viscosity and strength can be effectively optimized to meet the needs of engineering applications.First of all, temperature control is one of the key factors. In the production of rubber bitumen, t

28 2025-02: What is the reaction mechanism between polymer and bitumen?

The reaction mechanism between polymer and bitumenmainly involves the following aspects:1. Interaction mechanism: The interaction between polymer and bitumenis mainly achieved through physical and chemical reactions. Polymers can react with components in bitumenthrough cross-linkin

27 2025-02: Specific types of modified bitumen and their performance under different conditions

According to reference information, the specific types of modified bitumenmainly include PE (polyethylene), SBS (styrene-butadiene-styrene), SBR (styrene-butadiene copolymer) and EVA (ethylene-vinyl acetate copolymer). The performance of these modifiers under different conditions is as follows

18 2025-02: What problems does the difference between imported and domestic bitumen in the softening point modification effect reflect?
