Paver

Asphalt paver  is a complex linear road construction machine. Asphalt pavers are designed for laying layers of asphalt concrete pavement, including the distribution and preliminary compaction of the asphalt mixture over the underlying layer of pavement. Usually works in tandem with a truck that supplies the mixture for him.

The design of the paver was developed by Barber Greene (USA) and a patent was filed for it on August 20, 1932. On April 10, 1936, the US Patent Office issued a patent for «Machine for and process of laying roads».

Automatic leveling for asphalt pavers

The design of all modern asphalt pavers provides for the possibility of automatic control of the processes of supply, distribution and laying of pavement material. High-quality construction of the coating cannot be performed without the use of leveling automation to control the working body of the stacker, except for small, scattered areas. When building simple objects, the paver is equipped with at least sensors for controlling the supply of material to the distribution auger, a slope sensor that controls the angle of inclination of the slab to the horizon, one or two height sensors that control the thickness of the layer to be laid. At critical sites, especially when laying a wide strip of pavement, with the slab extended, more complex automatic leveling systems are used. ACS for asphalt pavers and other SDM according to the method of transmission and processing of the control signal are divided into digital and analog. Digital devices are created taking into account the maximum use of the latest achievements in the field of computer technology. Leveling automation systems, completed on their basis, are universal, multifunctional, provide the possibility of using various combinations of sensors, for example, one set of automated control systems may include an ultrasonic non-contact height sensor and a sensor-receiver of laser planes.
