Long life aslt pavement
ZTA-RA Anti-rutting Aslt Additives is a high-performance aslt mixture modifier that is superior to the modified aslt processing process, in particular improved the performance of road surface of low temperature resistance, anti-water loss, anti-ruttings. And significantly increased the Marshall Stability of the Aslt, improve the low temperature bending strain coefficient, and immersion stability.
ZTA-RA is suitable for new aslt pavements and road maintenance projects in high temperature regions, which effectively reduces the harm of road ruts caused due to insufficient high temperature performance. It improves the high temperature performance and the resistance of water loss of aslt, which reduces the possibility of rutting from high temperature sprinkling in summer.

Packing:3kgs or 4kgs per hot-melt bag, 24 kgs per bag.500KGS/ TON OF BAG, 25KGS/BAG, OR AS CUSTOMZIEDLoading:15 tons per 20 feet container. 27 tons per 40 feet container.
1. The dosage is smaller and the effect is remarkable. The dosage is 0.3-0.4% of the aslt mixture, and the dynamic stability can be increased from 1500 to about 10000.
2.ZTA-RA improves the high temperature performance of aslt mixture, and the aslt has strong resistance to deformation in summer and effectively resists pavement deformation and prevents the appearance of road rutting.
3. Application process easy: It's ready-to-use product. dosed directly into the pugmill of aslt plants. The aslt modification process and the mixture mixing production are integrated into one process.
4. The strong viscosity of ZTA-RA increases the softening point of aslt, reduces the sensitivity to temperature of aslt, and increases the adhesion of bitumen to mineral aggregates.
5. Packaged in “ton bag†or hot-melt bags, it is easy to transport and store at room temperature.
6. 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.
7. Dosing by quantity to be produced. It facilitates the use of many small batch projects, and facilitates long-distance use and storage.
8.For all types of surface and base aslt layers.
This product is mainly used in the middle, upper and lower layers of aslt pavement construction and maintenance engineering for all types of surface and base layers. Anti-rutting pavement aslt additive for aslt mix are widely used in mountainous roads, especially on ull sections, heavy-duty sections, crossroads, bus harbors, highways and high-grade roads, airport runways, municipal roads, bus lanes, container yards, various repaired pavements. , and the addition of aslt concrete pavement, etc., especially suitable for high temperature areas.
