bituminous binder sprayer
machine used to apply a film of bituminous binder on a pavement at a predetermined application rate Note 1 to entry: The particular sprayer types may be defined by associating the operating principle, the shape of the components, the type of binder, and by specifying the spraying performances.
synchronised combined unit
synchronous bituminous binder sprayer-chip spreader
machine which consists of a combination of bituminous binder sprayer (3.1) and chip spreader, used to make synchronised application of bituminous binder and chips on a pavement at predetermined application rate for a complete road surface treatment
displacement pump sprayer
bituminous binder sprayer (3.1) in which bituminous binder transfer from the storage tank to the spray bar is provided by a pump
Note 1 to entry: The pump’s output is proportional to its rotating speed which may be controlled by the vehicle movement speed.
4 Description of sprayer components
4.1 Transport vehicle The vehicle, in the form of a truck, trailer or semi-trailer, carries all the components and provides movement of the sprayer during spraying and during road transfers.
4.2 Tank The tank is used to store the binder during work and transport. It may have a facility to heat the binder and may have a system to prevent loss of heat, e.g. a heat- insulated sprayer.
4.3 Binder transfer device The binder transfer device provides transfer of the binder from the tank to the spray bar in order to apply a specific quantity to the pavement.
4.4 Spray bar The spray bar distributes the binder uniformly across the pavement.
4.5 Control station The control station contains all the control, adjustment, measuring and automatic control equipment. There are two types, as follows. a) Manual control: the operator adjusts all the operating parameters to obtain the required application rate. b) Automatic control: using predetermined operating parameters, automation ensures accuracy of the application rate.
