About Spraytech’s Asphalt Paving & Bitumen Nozzles:
Asphalt Paving & Bitumen Nozzles by Copley are approved by Austroads and the Australian Asphalt Pavement Association. The nozzles are available with various orifice sizes to give different rates of application, and specially- designed end nozzles are available.
These nozzles, manufactured to meet this specification, are marked A, B or S (EA, EB or ES for End Nozzles) plus two numbers for the capacity size.
Range of sizes and discharge rates
For each size of intermediate nozzle, there is a corresponding END NOZZLE marked as:
EB36, EB27, EA18, (EA18W), EA14, ES9, ES4.5
The discharge rates of end nozzles are approximately double that of the same intermediate nozzles.
