Compared with the traditional definition of hot and high-temperature recovery raw materials for emulsion bitumen machine, the method of recovery using normal temperature or low-temperature hot raw materials is cold patching. The common recovery raw materials are cold patching raw materials.
The difference between emulsion bitumen equipment concrete and general restoration raw materials is that it has bonding properties and loose characteristics. Compared with traditional hot patching, it avoids the traditional hot patching production processes such as square patching of round pits and brushing with bottom oil, and makes up for the disadvantages of traditional hot patching operations. The low temperature in winter and rainy season prevents construction, which saves the inconvenience of setting up pots and stoves to heat the bitumen on site.

This kind of material can be used to restore various types of floor coverings in any weather and geographical environment at operating temperatures between -30°C and 50°C. It will not pollute air and groundwater, and can be replenished as it breaks down. After recovery, Urban traffic can be restored by simple destructive compaction, human resource compaction, or tire rolling.
Its strong anti-aging and bonding properties make the restored pavement less likely to fall off or crack, and its service life can be more than five years.
The raw materials for emulsion bitumen equipment currently on the market refer to discolored bitumen, sand and gravel of various colors, and dyes that are mixed and stirred at a unique temperature to form bitumen mixtures of various colors, which are then paved, rolled, and mixed. It is rolled and recycled to form a colorful asphalt road concrete pavement with certain tensile strength and road characteristics, also called emulsion bitumen equipment.
