Parameters

Asphalt cold patch material describe

Traditional asphalt cold patch	Our High viscosity quick setting waterproof asphalt cold patch
1. Long curing cycle of the surface layer: rutting, bulging, cracks, etc. will appear after paving and opening to traffic due to the uncured surface layer, which seriously affects the service life of the cold patch material.	1. The surface layer solidifies quickly, and traffic is immediately opened after paving and compaction, which is not easy to produce rutting, bulging, and cracks.
2. Softening due to high temperature in summer: Traditional asphalt cold patch materials on the market use a physical change production method, which leads to a large amount of solvent inside that is difficult to volatilize. The solvent softening point is extremely low. The high temperature in summer causes the cold patch material to soften and needs to be dug out and re-paved.	2. It adopts a unique chemical change method, which can be used at -20℃ to +40℃. It does not soften in summer and does not freeze and crack in winter. It also takes into account high and low temperature performance, solving the problem that cold patch materials need to be dug out and re-paved in summer.
3. Threshing problem after rain: Because the production process of the cold patch material itself uses a single grade, and contains a large amount of difficult-to-volatile solvents, its porosity and water permeability are too high. After heavy rain, rainwater penetrates into the interior, causing water isolation of the mixture. After repeated rolling by vehicles, dispersion and threshing occur.	3. Due to its unique plasticizing characteristics, after paving and compaction, it has strong resistance to water damage and is fully adapted to the rainy and humid climate in the south.
	4. During the production process, the stone maintains a dryness of more than 85% (no water and no moisture visible to the naked eye), and can be cold mixed throughout the process without heating, saving fuel costs, environmental protection and low carbon.
