Snow Removal for Ice Melt Chemical Melt Ice and Snow on Roads Mixing Into Asphalt Mixture

    ZTA Environmentally-friendly Asphalt Snow Agent is a slow-release melt snow asphalt additives, under continuous moisture and low temperature conditions, through the rolling of the vehicle, the mixture continuously releases de-ice ingredients to prevent road frozen.

    ZTA environmentally friendly asphalt melt snow & de-ice additive has a characteristic of environmental protection, long-term, and safe. The Additives is a powder, replaces the mineral powder, which replaces some of the mineral powder into hot asphalt mixture, generally dosage is 3% - 5% of asphalt mixture, and its application is widely used. It can reduce the road frozen temperature to -25 ° C, while significantly improving the long-term performance of the melt-ice of road pavement, the service life is 6-8 years, which is equivalent with the life of asphalt pavement. It realizes that any asphalt pavement can have the function of melt-snow and inhibitory ice, and it is the most efficient and economical snow inhibitory application model.

                  Small snow can melt                             Heavy Snow is not frozen with pavement

Slim-release types of anti-condensate ice asphalt road, with high cost-effective and significant economic benefits

1. ZTA melt Snow and anti-frozen agent and its mechanism

    It is mainly to store the freezing degradation agent (inorganic halide) in a mustable form and wrapped by a hydrophobic material (organic polyol-based compound). By osmotic pressure and capillary, the ice point degrading agent in the ZTA additive forms ion migration, gradually precipitating to the road surface, thereby melting the snow of the road, reducing the road icing point, inhibiting thin ice.

    Since the material has a sustained release form of the "Nuclear-Shell Capsule" structure, the effective ingredient can be released for up to 6 to 8 years. Even if it is effectively analyzed, the volume skeleton of its porous material is still there. Avoiding the harm of cavity of asphalt mixture that due to increasing porosity due to effectiveness analysis.

2. Using Method

The use of ZTA Additive in hot asphalt mixture:

(1) Add ZTA additive on the basis of grading ration of original asphalt concrete.

(2) Replace the same proportion of mineral powder.

(3) Recommended dosage is 5% of the total mass of the mineral material (stone + mineral powder).

For example, 100% instead of the mineral powder in AC asphalt mixture, 50% instead of the mineral powder in SMA asphalt mixture, which accounts for about 5% of the mass of total minerals.

3. Advantage of ZTA melt snow and de-ice additives

1, Environmental protection. Reduces the environmental impact.

2, Reduce costs. Reduces the use of organic Organic melt snow agent and the cost of manual snow removal.

3, Easy to use. It is used directly when mixing the hot asphalt mixture.

4, High efficiency of melting snow. Snow and pavement interface are not easy to refrigerate, which is very good to shovel snow project.

5, Low cost.

6, Long effect of melting snow. The effect of melting snow and de-ice can be 6-8 years.

4. Application Range

    Directly applied to hot asphalt mixture, laying a conventional thickness of the upper layer. OR on the basis of the original pavement, milling of the original pavement, then paving 1.5-2.5cm thickness of asphalt thin overlay cover (newly built road pavement, preventive maintenance road pavement)

The upper layer of new asphalt pavement

Thin overlay cover of new asphalt pavement

Thin overlay of preventive maintenance pavement

Thin layer of old asphalt pavement
