1. Introduction to cold patch asphalt additive

Cold patch asphalt additive is a functional material used for repairing asphalt pavement under normal or low temperature conditions, which can maintain the workability of asphalt mixture without heating and quickly form strength. Suitable for emergency repairs, winter construction, and road maintenance in remote areas.

Cold patch asphalt additive is a main raw material for producing asphalt cold patching materials, composed of various polymers. The cold patch materials produced from it are suitable for repairing various types of road surface layers in any weather and environment, such as asphalt concrete roads, cement concrete roads, parking lots, airport runways, bridge expansion joints, etc. It is superior to general cold patching materials or traditional hot mix asphalt and emulsified asphalt mixtures in terms of cost, quality, and usage. With its characteristics of easy operation, long-term storage, good repair quality, wide application, and environmental friendliness, it has been widely used around the world.

2. Cold patch asphalt additive product series

Cold mix asphalt products, liquid cold mix asphalt, and cold mix asphalt additives.

3. Storage method for cold patch asphalt additives

Cold mix asphalt additives should be stored in sealed barrels at room temperature and can be stored for more than two years. The barrels should be stored in a cool or ventilated warehouse, and should not be placed in direct sunlight to prevent them from deteriorating due to heat. They should also be kept away from flammable materials and high oxidation materials.
