Knowledge related to high viscosity, high elasticity and high toughness modified bitumen
High-toughness and high-elastic modified bitumen is a chemically cross-linked special modified bitumen with a good three-dimensional modified network. Its softening point reaches above 85°C and its dynamic viscosity reaches above 580,000 Pa·s. It is a conventional high-viscosity modified bitumen. The dynamic viscosity is 3 times that of modified bitumen and has excellent high temperature performance. At the same time, its ductility reaches more than 45cm, excellent low-temperature crack resistance, elastic recovery exceeds 95%, excellent deformation recovery ability and high toughness and crack resistance.
High-toughness and high-elasticity modified bitumen mixture has excellent high-temperature stability, water stability, scattering resistance, high-toughness and crack resistance, deformation compliance and durability. This product has a wide range of application scenarios. The thickness of the ultra-thin overlay can be reduced to 1.2 cm, and the service life can be extended to up to 8 years. It can be used as a preventive maintenance overlay for bitumen pavements on various grades of highways and municipal roads, cement concrete pavements, and bridges. face and tunnel face. In addition, high-tenacity and high-elasticity modified bitumen can also be used in sponge city permeable pavements, stress absorption layers, waterproof bonding layers, etc.
