The method of repairing using normal temperature or low temperature cold materials is cold patching, and the repair material used is cold patching asphalt mixture.
Product Features
The high-performance cold repair material produced by our company still has good construction workability at low temperatures. The material has strong resistance to freezing damage, and the formula contains components to prevent freezing damage with strong bonding force. The finished material can be stored, and its performance remains stable for a long time. It can withstand vehicle maintenance, has the ability to resist rutting, and has fast strength.
