Chất phụ gia nhựa đường có độ nhớt cao cho mặt đường OGFC

high viscosity open-graded friction course (OGFC) pavement modifier asphalt agent

1. Product description:
It is a direct-injection high-viscosity asphalt modifier that improves the viscosity of asphalt by zhongtian road company. It is a special high viscosity modifier for drainage asphalt pavement suitable for high temperature and heavy load. The method of use can be added to the matrix asphalt to prepare high-viscosity asphalt or directly added to the stone to mix and produce high-viscosity asphalt mixture.

From the above index, the indicators of zt high-viscosity asphalt modifier meet and exceed the national & international technical standards.We master domestic leading road materials and new technologies, and some are at the international advanced level.

2. Packaging & shipping:
The high-viscosity asphalt mixture prepared by zt- high viscosity agent has high durability, high temperature stability, low temperature crack resistance, water stability and anti-aging performance, and has high anti-scattering property, water resistance, weather resistance and resistance to flow
The porous asphalt pavement has the advantages of high anti-sliding performance, low noise, water mist suppression, water drift prevention, glare reduction, etc., and it achieves the "ultimate performance" in the existing asphalt pavement technology.
Drainage asphalt pavement is called porous asphalt pavement, also known as low noise asphalt pavement.It has excellent drainage, anti-skid, noise reduction and other functions, and is a safe and environmentally friendly new technology for ecological asphalt pavement paving.
