Asphalt distributor (bitumen distributor) is a type of construction equipment, which uses truck chassis. It is intended for transportation and distribution of bitumen or bitumen emulsion on the roadbed.
Structurally, asphalt distributor is a special heat-insulated tank with a pump and a distribution pipe, which is mounted on the frame or equipped inside the body of a truck. As far as bituminous materials can be both cold and hot (the temperature is up to +200°C) during transportation, heating of the substance in the tank up to the desired temperature is conducted with the use of special diesel burners. The pump is usually powered by the engine of the vehicle chassis.
The main use of asphalt distributors is in construction and repair work on roads, paved areas and airfields. This equipment is widely used not only for delivery of liquid bituminous materials from the site of production to the site of storage or road works, but also directly for homogeneous distribution of these substances on the previously prepared surface of the roadbed or another specified area. It is an important feature of this type of construction equipment that it provides the possibility of adjusting the desired width of the strip for material distribution and its flow density (dosage per area unit).
Moreover, in construction works asphalt distributors are often used for treatment and dampproofing of the basements.
