TPS modified bitumen is a high-viscosity modified bitumen designed specifically for drainable bitumen concrete pavement. Its main component is thermoplastic rubber, supplemented by adhesive resin and plasticizer. Its biggest feature is that the viscosity can be as high as 160,000 Pa·s at 60°C, which plays a key role in improving the durability of drainable bitumen mixtures. The main advantages of TPS modified bitumen are reflected in the following aspects:

1. High viscosity and durability: The high viscosity of TPS modified bitumen enables it to maintain good performance under high temperature conditions, and can effectively resist the deformation and flow of the pavement at high temperatures, thereby extending the service life of the pavement.

2. Improved construction effect: After using TPS modifier, the use effect of the construction site is significantly improved, which can meet the strict requirements of the viscosity of the bitumen binder for drainable pavement, thereby improving the smoothness and efficiency of construction.

3. Enhanced impact resistance and cracking resistance: The modification process of TPS modified bitumen changes the rheological properties of bitumen, improves its viscoelasticity and ductility, enhances the impact resistance and cracking resistance of the pavement, and reduces maintenance costs.

4. Excellent waterproof performance: TPS modified bitumen improves the bonding between bitumen and aggregate, improves the strength and waterproof ability of bitumen mixture, enhances the durability of the pavement, and is particularly suitable for pavements that require drainage performance.

In summary, TPS modified bitumen has become an ideal choice for drainage pavement construction due to its high viscosity, excellent durability and construction effect.
