Anti-Rut Agent
Anti-Rut Agent
The appearance of anti-rutting agent pure black granular solid is a polymer composite by a variety of asphalt into the mixture additives, through the surface of thickening aggregates, reinforced, filled, as well as asphalt modification, the multiple role of the elastic recovery The substantial increase in the high temperature stability of asphalt mixture, and mixture of water stability and low temperature crack resistance also improved.

Intention
1）The role of embedded squeeze
Anti-rutting agent in the construction process, the role of high-temperature softening of the particles in the hot rolling process of forming, the equivalent of a high adhesion of a single particle size of fine aggregate fill pushed to the aggregate skeleton embedded in the gap, increasing of the asphalt mixture structure of the skeleton role in strengthening the interaction between the hybrid force is expected to enable mix between the more closely, reducing the permeability of the molding surface. while increasing the load of asphalt mixture withstand capability.
2）Reinforced
As the anti-rutting agent in the formation of micro-crystalline polymers have considerable stiffness, it is part of the mixing process of drawing into a plastic fibers, in the aggregate skeleton bridge formed by cross-linking the role of fiber reinforcement. As the presence of polymer fiber , which form a mesh in the cement compound enhanced the interaction between asphalt and slag cementitious material system integrity.
3）Cementation
Anti-rutting agent into the mixing pot of asphalt mixture, in the 170 ~ 180 ° C temperature, first with the mineral aggregate dry mix to make it soften and continue to join the asphalt mixing, anti-rutting agent particles and the formation of cementation asphalt, so that asphalt performance is improved. improved asphalt softening point; reduces the temperature sensitivity; an increase of asphalt and mineral aggregate adhesion.
4）Recovery effect
Anti-Rut agent elastic component in high temperature deformation of the road when you have to make part of the elastic recovery of the function, thereby reducing the molding of asphalt pavement permanent deformation.
Applications
1）Road: highway and high-grade highways, especially suitable for high temperature areas, heavy traffic roads, and grew up in sections Zongpo；
2）Municipal Road: Municipal roads, bus lanes and so on, especially for intersections and bus stops；
3）Airport Project: Airport Runway。
Help
一、Proportional
Agent dose of anti-rutting of asphalt mixture for 0.3 ~ 0.5% per ton of asphalt mixture that is doped with 3 ~ 5KG. For the road are generally doped 0.35-0.4% per ton of asphalt mixture that is doped with 3.5-4KG you can. traffic volume, heavy-duty vehicles and more with high limits, special sections may be doped more than 0.6%.
二、Construction Technology
Anti-Rut agent technology to facilitate the use of simple, through the mixing process of asphalt mixture directly into:
1. The ore material heated to 170 ~ 180 ° C, it will be additive directly into mixing pot to dry mixing, mixing time, increase 2 ~ 3 seconds.
2. Add hot asphalt to mixing, mixing time can be correspondingly increased.
3. Finished mixture of quality control and storage of transport carried out according to the conventional mix.
