Asphalt is a complex polymer hydrocarbon. The road surface paved with asphalt is a continuous road surface without joints, but it will cause aging under high temperature and ultraviolet radiation. Therefore, the main purpose of adding modifier is to improve the road performance of asphalt mixture at high temperature. |
Due to the increasing traffic and heavier vehicles, the requirements for the quality of asphalt pavement are becoming higher and higher. Ordinary petroleum asphalt is easy to brittle at low temperature and soften at high temperature. Rutting and transition are prone to occur under the repeated action of driving load. Phenomenon such as packing, the performance has been unable to meet the needs, and the use of nano-calcium carbonate modified asphalt to solve the problems of high and low temperature resistance, slip resistance, durability and large bearing capacity of the pavement is one of the advanced technologies at home and abroad. |
The use of nano-calcium carbonate for modified asphalt can make the asphalt pavement have good durability and abrasion resistance, and it does not soften at high temperature and does not crack at low temperature. The modified asphalt with nano-calcium carbonate can greatly improve the performance of pavement. |
The characteristics of the modified bitumen nanometer calcium carbonate modified asphalt: |
1. High temperature resistance, low temperature resistance, strong adaptability; can improve flexibility and elasticity, so that the road surface has the ability to resist cracking at low temperature; |
2. Good toughness, anti-fatigue, increase the carrying capacity of the pavement; can further improve the pavement anti-fluidity, so that the pavement has the ability to resist rutting under high temperature; |
3. Resist water, oil and ultraviolet radiation to delay aging; |
4. Stable performance and long service life, reduce maintenance costs. |
5. The production cost of modified asphalt can be significantly reduced. |
