Asphalt Modifiers for 1.5cm to 2.5cm Ultra Thin Asphalt Overlay Asphalt Cover

1. Introduction

   The asphalt mixture of ZTS ultra-thin asphalt overlay has a relatively large structure depth and good durability. It adopts a dense skeleton type of multiple gravel gradation, with more coarse aggregates, large structure depth and good anti-skid performance. More mineral powder and fine aggregates are effectively filled in the voids of the coarse aggregate to form a dense structure. The addition of ZTA-VE additive improves the bonding performance of asphalt, so that the flying loss of asphalt of ZTS high-elastic anti-cracking ultra-thin asphalt overlay is very small, generally only about 3%.

    ZTA-VE Asphalt Modifiers for 1.5cm to 2.5cm Ultra Thin Asphalt Overlay Asphalt Cover is a new type of composite asphalt additive developed by Beijing Zhongtian Road Tech Co. Ltd. This additive combines the technical characteristics of high viscosity, high elasticity, wide temperature range, and warm mixing. The high temperature and low temperature performance of asphalt mixture reduces the difficulty of road construction, energy saving and environmental protection.

2. Advantages of ZTA-VE modified asphalt mixture.

1. ZTA-VE additive and aggregates are mixed in asphalt mixing plant, and the production and construction process of the asphalt mixture is simple.
2. It integrates a variety of technical features such as high viscosity, high elasticity, wide temperature range, and warm mixing. (Strong bonding ability, good low temperature performance, wider temperature range, Good warm mixing effect, low smoke and dust emission.)
3. ZTA-VE additive has an effective reinforcement effect in asphalt.
4. Multi-gravel structure to ensure the strength of the road surface, increase depth of structure, and improve the anti-skid performance of asphalt overlay.
5. No special equipment is needed, no special emulsified bitumen is needed, and construction is more convenient.

    ZTA-VE high-elastic anti-cracking additives are directly added to the conventional asphalt mixture to improve the high temerature and low temperature performance, crack resistance and fatigue resistance of asphalt mixture. Restores the road's anti-skid, noise reduction and comfortable driving in all aspects.

1. Good bonding performance. Significantly improve the bonding performance of the mixture to avoid flying particles.

2. Easy to use. The production and construction processes are very simple, directly modify the asphalt mixture without special paving equipment.

3. Convenient for small batch applications. It meets the preventive maintenance needs with a small amount of engineering.

4. It adopts multi-gravel type asphalt mixture with wide gradation range, strong adaptability, large structure depth, excellent anti-skid and noise reduction performance, and good material stability within a large oil-stone ratio range, and better construction tolerance conducive to production and construction control.

5. Warm mixing performance. The discharging temperature of the mixture should be above 160°C, and the ambient temperature can be well rolled at 5°C, which avoids the adverse effect of rapid cooling of the ultra-thin cover surface on compaction.

6. Good durability and high cost performance.

7. Environmentally-friendly. Energy-saving and environmentally-friendly technology with little smoke and dust.
