Asphalt cold patch material is a premixed mixture made of high-performance modified emulsified asphalt or room temperature modified asphalt as a binder and mixed with reasonably graded aggregates (crushed stone, sand). Its core lies in the special cold patch additive, which enables it to have good adhesion and strength even in low temperature and humid environments.

Asphalt cold patch Product features

• Construction at room temperature; no heating equipment is required, it can be used immediately after opening the bag, suitable for emergency repair construction in all seasons, especially in rainy season or cold weather.

• Easy to operate; it can be completed by manual or small mechanical paving and compaction, with fast construction speed and low labor intensity.

• Environmental protection and energy saving; no smoke, no odor, no high temperature heating, reducing energy consumption and environmental pollution.

• Quick opening of traffic; it can be opened to traffic after construction is completed, without affecting traffic operation.

• Good adhesion and durability; it can also be firmly bonded in wet pits and grooves, has strong water damage resistance, and is not easy to fall off after repair.

• Can be stored for a long time; it can be stored for 6 to 12 months under normal temperature and sealed conditions, suitable for large-scale prefabrication and standby.

FAQ

What is the difference between cold asphalt patch and hot asphalt?

• Cold patch is used at room temperature, does not require heating equipment, and is easy and quick to construct;

• Hot asphalt needs to be heated at high temperature (above 120°C) before it can be used, with a long construction period and high cost;

• Cold patch is more suitable for small-area repairs and sections of uninterrupted traffic, especially in cold or wet weather

Can the cold patch material be used when the road surface is wet during construction?

• Yes. The cold patch material uses a special modified asphalt binder, which can maintain good adhesion even in wet conditions. However, it is necessary to remove the water in the pit.

How long after the cold patch material is constructed can it be opened to traffic?

• Generally, it can be opened to traffic after compaction. It is recommended to open traffic after repeated rolling by vehicles to achieve better compaction effect.

 How long can the cold patch material be stored?

• Store in a cool and dry environment with a shelf life of 6 to 12 months. Please use it as soon as possible after opening to prevent the material from becoming ineffective.

 Can the cold patch material be used in winter? How is the effect at low temperatures?

• It can be used. The cold patch material is suitable for environments between -20℃ and 50℃. Construction at low temperatures still maintains good operability and adhesion, which is suitable for emergency repairs in winter.
