1 Scope
This document establishes the terminology and the content of commercial literature specifications for bituminous binder sprayers and synchronous bituminous binder sprayers-chip spreaders (i.e. synchronised combined units) including their components and their technical characteristics. This document covers cold and hot bituminous binder sprayers.

3.1 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.
3.2 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
3.3 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.
3.14 nominal application rate
application rate at maximum output of a pumping unit (3.13) moving at a speed of 4 km/h with a binder of a density of 1 g/cm 3 and a viscosity of 100 mm 2 /s and with maximum spray bar width (3.12)
Note 1 to entry: It is expressed in kilograms per square metre.
3.15 binder carrying capacity
difference between the laden and kerb mass of a sprayer or synchronised combined unit (3.2)
3.16 spraying height
height measured between the average plane of the pavement and the orifice of the nozzles
Note 1 to entry: It is expressed in millimetres.
Note 2 to entry: See h 2 in Figure 8.
