Ultra Thin Asphalt Overlay Efficient Way of Road Pavement Preventive Maintenance

Product Description

ZTA Ultra Thin Asphalt Overlay Efficient Way of Road Pavement Preventive Maintenance is an efficient means of pavement preventive maintenance, which does not destroy the structure of the original pavement without reducing its structural strength. Compared with other thin layer of asphalt cover technology, the ZTS ultra-thin asphalt cover does not require special high viscosity High viscosity emulsified bitumen and dedicated paving units, which can significantly reduce costs, so that the ultra-thin cover can be widely used. The thickness of ZTA high-elastic anti-crack ultra-thin asphalt cover is 1.5cm-2.5cm. ZTA-VE high-elastic anti-crack additives can increase the adhesion between aggregates and bitumen, which can reduce the amount of bitumen and ensure the performance of the asphalt mixture, thereby achieving the purpose of reducing cost. It is an economical and high performance road preventive maintenance technology.

Our Advantages

ZTA high-elastic anti-cracking additives are directly added to the conventional asphalt mixture to improve the high 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.
