2.19
maximum output of pumping unit
largest capacity for a binder with a viscosity of 100 cSt
NOTE It is e*pressed in cubic metres per hotx.
2.20
nominal application rate
application rate at maximum output of a pumping unit moving at a speed of 4 kmiti with a binder of a density of
1 g/cm3 and a viscosity of 100 cSt and with maximum spray bar width
NOTE It is expressed in kiloams per square metre,
2.21
binder carrying capacity
difference between the laden and kert mass of a spreader
2.22
spreading height
height measured between the average plane of the pavement and the orifice of the nozzles
NOTE I It is ewfessed in metres.
NOTE2 See#2lnFigurel,
3 Description of spreader components
3.1 Transport vehicle
This vehicle, ii the form of a truck, trailer or semi-trailer, carries all the components and provides movement of the
spreader during spreading and during road transfers.
3.2 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 10 protect against loss of heat.
3.3 Binder transfer device
This device provides transfer of the binder from the tank to the spray bar in order to apply a specific quantity to the pavement.
3.4 Spray bar
The spray bar distributes the binder uniformly across the pavement
3.5 Control station
The control station contains all the control, adiustment. 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: usrng predetermred operating parameters, automation ensures accuracy of the application rate
4.7 Control station perfomiance
4.7.1 Positioning, control and adjustment equipment
The type of equipment shall be specified fo. adjustment of:
— spray bar height;
opening of nozzles:
— general control,
individual control;
transverse movement of the spray bar;
spreading width.
4.7.2 Measuring and automatic control equipment
The following equipment shall be specthed:
— pump speed indicator:
— truck speed indicator;
spray bar pressure gauge:
binder thermometer in tank;
automatic correction device for spray bar height;
automatic proportioning control and adjustment box;
— control to move the vehicle forward at regular speed:
means of displaying, pnnting and storing parameters during austment and spreading:
— remote control box.
