Road Rutting Prevention Asphalt Additives Asphalt Modifier
Long life asphalt pavement
1. Description
Road Rutting Prevention Asphalt Additives Asphalt Modifier is a asphalt additive composed of a variety of refined polymer polymers, and it greatly improves the high temperature stability of the asphalt by tackifying, reinforced, filling, and asphalt elastic recovery, and a large improvement and enhancement of the water stability and low temperature crack resistance of the asphalt mixture.
ZTA-RA additive is filled into the gap of the assembly skeleton during the road surface molding, enhances the skeleton effect of the asphalt, and improves the ability of the asphalt to withstand load. The polymers in ZTA-RA are partially brushed in the mixing process to form a plastic fiber, and crosslink in the assembly skeleton, so that the pavement has a large elastic recovery function at a higher temperature, thereby reducing the risk of permanent deformation of the shaped asphalt pavement.

3. Advantages
1. Usage performance advantages: good mixing uniformity, better dispersion, stable quality
2. Application process easy: It's ready-to-use product. dosed directly into the pugmill of asphalt plants. The asphalt modification process and the mixture mixing production are integrated into one process.
3. The modification performance is more stable.
4. Packaged in “ton bag” or hot-melt bags, it is easy to transport and store at room temperature.
5. It replaces sbs in high and low temperature road performance, and its dynamic stability can reach 15000 times/mm, which is much higher than sbs, with more higher high temperature performance for a stonger and greater longvity of roads.
6. Customers can produce extremely thin asphalt mixes that can withstand high loads. This definitely improves the mechanical performance of the road and significantly increases its service life!
4. Application Scope
This product is mainly used in the middle, upper and lower layers of asphalt pavement construction and maintenance engineering for all types of surface and base layers.
Highway: Highway and high-grade roads, especially suitable for high temperature regions, heavy traffic sections and long slope road sections.
Municipal roads: municipal roadways, bus lanes, etc., especially suitable for crossroads and bus stations.
Airport Engineering: Airport Runway, etc.
