Construction seasons



Be constructed in all weather in a whole year, not influenced by winter or raining/snowing weather

Not constructed in low temperature winter and raining weather

The temperature is required not below 5°C, and the construction time is longer then the hot paving.

Holes/trench treatment



Just simple treatment, the holes/trench with gathered water can be filled directly 

Cleaning-up, removing gathered water, drying them up, and brushing with bonding oil are necessary 

Cleaning-up, shaping and removing gathered water are necessary 




The fill-bag sealed finished product can be stored as long as two years at room temperature

Can not be stored

Stored for 3-7 days or longer at 20°C 

Construction performance



Neither proficient workers nor special machines is needed

Proficient workers and special machines are needed

Proficient workers and special machines are needed

Production environment




Can be produced locally or pre-stirred in factory, without the smell of hot asphalt 

Stirring in factory is needed, with heavy smell of hot asphalt

Pre-stirring in factory is needed

Utilization rate of the material



Be taken at anytime if needed, and the left material can be used for next time.

The taken amount is more than the utilized amount, and the left material is invalid.

The material can not be used again after the emulsion breaks

Opening for the traffic



The traffic is opened immediately after the patching is finished.

The traffic is closed for a period after the patching is finished

The traffic is closed after the patching is finished, waiting for the emulsion to break.




The lifetime is as long as 10 years



Consume of energy



The stone materials are generally not required to be heated, and the temperature of asphalt is low, so the energy is saved.

the stone materials and asphalt are required to be heated

Amount of asphalt consumed is 10% less than that of the hot patching material, and the stone materials is not heated, and the temperature of asphalt is high.

Material consume 



Repeated repairs are reduced and material is saved; the shutdown cost caused by winter and raining weather is reduced

Waste is caused by taking larger amount of material to keep it warm; and the damage aggravates due to the patching can not be constructed at any time.

Generally the patching can be constructed in time, and the amount is taken according to the actual need. The cost on the shutdown of the construction and the machines is reduced to some extent. 

Social benefit



Patching is constructed at any time to maintain the pavement fresh all the time, which makes the traffic smooth, reduces traffic accidents and the patching times, and prolongs the serving life of the roads.

The patching can not be constructed at any time, which aggravates the impairment, influences the traffic, and reduces the serving life of the roads.
