2 Terms and definitions
For the purposes of this International Standard, the following terms and definitions apply.
bituminous binder spreader
machine used to apply a film of binder on a pavement at a predetermined application rate
NOTE The particular spreader types may be defined by associating the operating principle, the shape of the components, the type of binder, and by specifying the spreading performances.
2.2
displacement pump spreader
machine in which binder transfer from the storage tank to the spray bar is provided by a pump
NOTE The pump’s output is proportional to its rotating speed which may be controlled by the vehicle movement speed.
2.3
constant pressure spreader
machine in which binder transfer from the storage tank to the spray bar is provided by pressurizing the binder
NOTE The binder may be pressurized directly by compressed air above the binder, or by a pump and regulating valve maintaining a constant binder pressure in the spray bar feeder circuit.
2.4
fixed assembly spreader
machine in which the tank and its attachments are fixed to the transport vehicle
2.5
removable assembly spreader
machine in which the tank and its attachments are fixed to a removable chassis
2.6
heat-insulated spreader
machine in which the tank is equipped with thermal insulation to avoid heat loss
2.7
directly heated spreader
machine with heating provided by circulation of hot gases in a tube or by an electrical resistor in contact with the binder
2.8
indirectly heated spreader
machine with heating provided by circulation of a hot liquid supplied by a generator outside or inside the spreader
2.9
hot binder spreader
machine which enables application of binder at a temperature greater than 80 °C
2.10
cold binder spreader
machine which spreads binders at a temperature lower than 80 °C
high-viscosity-binder spreader
machine which enables application of a binder with a viscosity greater than 300 cSt at the application temperature
2.12
high-binder-pressure spreader
machine in which the binder pressure in the spray bar during spreading is greater than 0,2 MPa
2.13
medium-binder-pressure spreader
machine in which the binder pressure in the spray bar during spreading is between 0,02 MPa and 0,2 MPa
2.14
low-binder-pressure spreader
machine in which the binder pressure in the spray bar during spreading is less than 0,02 MPa
2.15
tank volume
internal volume of the tank
NOTE It is expressed in cubic metres.
2.16
rated capacity
volume of binder which can be carried
NOTE It is expressed in cubic metres.
2.17
nominal loading of tank
loading using the available capacity of the binder with the highest density
NOTE It is expressed in kilograms.
2.18
spray bar width
distance between end flow points
NOTE It is expressed in metres.
