bituminous binder sprayer
machine used to apply a film of bituminous binder on a pavement at a predetermined application rateNote 1 to entry:The particular sprayer types may be defined by associating the operating principle, the shape ofthe 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, usedto make synchronised application of bituminous binder and chips on a pavement at predeterminedapplication 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 spraybar 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 vehiclemovement speed.
nominal application rate
application rate at maximum output of a pumping unit(3.13) moving at a speed of 4 km/h with a binderof a density of 1 g/cm3 and a viscosity of 100 mm2/s and with maximum spray bar width (3.12)
Note 1 to entry: lt is expressed in kilograms per square metre.
binder carrying capacity
difference between the laden and kerb mass of a sprayer or synchronised combined unit (3.2)3.16
height measured between the average plane of the pavement and the orifice of the nozzlesNote 1 to entry: lt is expressed in millimetres.
Note 2 to entry: See hz in Figure 8.
4 Description of sprayer components
The vehicle, in the form of a truck, trailer or semi-trailer, carries all the components and providesmovement of the sprayer during spraying and during road transfers.
The tank is used to store the binder during work and transport.
lt may have a facility to heat the binder and may have a system to prevent loss of heat, e.g. a heat-insulated sprayer.
4.3Binder transfer device
The binder transfer device provides transfer of the binder from the tank to the spray bar in order toapply a specific quantity to the pavement.
The spray bar distributes the binder uniformly across the pavement.4.5Control 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
b) Automatic control: using predetermined operating parameters, automation ensures accuracy of
the application rate.
5 Commercial specifications of bituminous binder sprayers and spraying part of synchronised combined unit
The components and dimensions of a bituminous binder sprayer and spraying part of a synchronised combined unit shall be specified according to Clause 4 and 5.
The spreading part of a synchronised combined unit shall be specified according to Clause 6.
5.2 Binder sprayer components list
