Description

Technical Field

[0002] An asphalt spreader is a tank-type special-purpose vehicle equipped with an insulation container, an output pump, a heater and a spraying system for spraying asphalt. It can also be defined as a road construction machinery for spraying hot asphalt, emulsified asphalt, residual oil and other liquid asphalt. It can be widely used in road construction such as highways, urban roads, airports, ports and reservoirs. Large-capacity asphalt spreaders can also be used as asphalt transport vehicles, mainly used in construction and maintenance projects such as asphalt penetration method surface treatment, penetration layer, bonding layer, on-site mixing of mixtures, asphalt stabilized soil, etc.
