Product description
Product Introduction
In road maintenance engineering, compared with the traditional hot-state high-temperature repair concept, the cold repair at normal temperature or low temperature is called cold repair. The material used for cold repair is cold patch material, English: C01d Patch. Specifically, asphalt cold patching material refers to a mixture formed by mixing unheated mineral material (aggregate) and diluted asphalt. According to the mixing form, it can be divided into two types: factory mixing and on-site mixing. Compared with ordinary hot mix, asphalt cold patch material is a high-tech road patch material that can be used around the clock. It is suitable for repairing various types of road surfaces in any weather and environment, such as asphalt concrete roads, cement concrete roads, parking lots, airport runways, bridge expansion joints, etc.
Cold patch characteristics
1. All-weather repair materials
The cold patching material is suitable for a wide range of ambient temperatures, which can be applied between -30°C and 50°C, and can repair pits in time under harsh environmental conditions such as rain, snow, and humidity.
2. Simple construction
There is no need for sticky layer oil when using cold patch to repair pavement potholes. The preparation materials can be picked up at any time without heavy construction machinery. According to the different repair conditions of the road surface, impact compaction, manual compaction or automobile tire rolling can be used. In addition, the area repaired with cold patching materials does not need to be closed to traffic, and can be opened to traffic immediately, which greatly relieves the traffic pressure caused by road repair construction.
3. Wide range of applications
The cold patching material has good adhesion to asphalt concrete, cement concrete, metal surface, wood surface and other materials of different substrates, and can be widely used in road surface restoration after damaged potholes, excavated potholes, underground pipelines, Repair and maintenance around manhole covers, bridge pavements, parking lots, airport runways and hard-to-reach parts of construction machinery.
4. Excellent quality
The cold patching path has strong anti-aging and bonding properties. The service life of the repaired pits is more than 10 years, and it is not easy to cause falling off, cracking and other adverse phenomena, and does not need to be repaired repeatedly.
5. Low repair cost
When using cold patch materials for construction, it is not limited by the weather and the size and number of pits, and there is no need to heat or stir during repairs. It can be taken at any time according to the actual amount. The remaining materials can be used in the next repair without causing material waste. ． Really 100% exploited. It will be the most economical and effective to replace the traditional centralized repair method with anytime repair method.
6. Convenient transportation
The area repaired with cold patch does not need to be closed to traffic, and can be opened to traffic immediately, which can greatly relieve the traffic pressure caused by road repair construction.
7. Environmental protection
The production and use of cold patch materials will not produce asphalt black smoke and waste, and the finished product is insoluble in water, so it will not pollute the atmosphere and groundwater, which is beneficial to environmental protection.
8. Easy to save
Cold patch can be stored indoors or outdoors without covering. If bulk material is stored, it is recommended to store at least 20-30 tons of cold patch, and it should be piled up in a pyramid shape. The shell formed for a long time can be mixed with the internal loose material for use. Bulk materials can be stored for more than two years, and bags can be stored indefinitely without caking. When constructing at low temperature, it should be stored in a warehouse above 5°C for 24 hours before proceeding.
9. Remarkable social benefits
The use of asphalt cold patching materials can repair potholes in time, keep the road surface smooth and beautiful, ensure smooth roads, reduce the number of road surface repairs and workload, and prolong the service life of the road.
