ZTA Thin Asphalt Overlay for Pavement Preservation Maintenance Highway Road Maintenance breaks through the limitations of traditional asphalt overlay technology that requires the use of high-viscosity emulsified bitumen, high-viscosity modified bitumen and special integrated paving equipment. It uses ordinary emulsified asphalt, ordinary asphalt and ordinary paving equipment. It adopts ordinary emulsified bitumen, ordinary bitumen and ordinary paving equipment to realize paving with high elasticity and anti-cracking ultra-thin asphalt overlay. It completely reduces the construction difficulty of the ultra-thin asphalt overlay, and the cost is lower than that of the traditional ultra-thin asphalt overlay.
ZTA-VE asphalt modifier added to the ZTA high-elastic anti-crack ultra-thin asphalt cover can increase the properties of the asphalt mixture to adapt to high and low temperature, anti-scaling and anti-fatigue properties. Its construction application is more convenient that ZTA-VE additives is directly mixing with aggregates in asphalt mixing plants. ZTA-VE is a asphalt additive for ultra-thin cover of road preventive maintenance, dosage is 0.4% of asphalt mixture. It effectively enhances the bonding, anti-cracking, anti-stripping ability of the asphalt mixture, and extends the service life of the pavement.

1.5cm ZTA anti-crack ultra-thin cover
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.
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.)
ZTA-VE additive has an effective reinforcement effect in asphalt.
Multi-gravel structure to ensure the strength of the road surface, increase depth of structure, and improve the anti-skid performance of asphalt overlay.
No special equipment is needed, no special emulsified bitumen is needed, and construction is more convenient.
