APPLICATION RATE CONTROL for BITUMEN SPRAYERS

Bitumen sealing operations have undergone immense change in the last decade. Not only has the cost of materials increased to unpredictable levels, but also have the technical and contractual obligations. This means that not only by the application rate be accurate, but the control system should also be predictable and easy to use.

Paving plant & Processes has a wide range of experience in manufacturing and refitting bitumen sprayers and can provide a control solution to suit your equipment and environment.

SR-1 Application Rate Indicator

Low Cost
Tank or cab mounted
Easy to operate and calibrate
Low cost

A low cost electronic control system for accurate and easy to use bitumen application rate control. The Operator selects the spraybar application width as the number of spray nozzles required, then adjusts the pump speed until the display indicates the correct number of spray nozzles. The desired application rate in Litres/Square Metre is then selected for the spray run. While spraying, the driver controls vehicle speed so the application rate meter, mounted on the dash board reads zero error.

MultiRate Application Rate Control
A new concept in Bitumen Sprayer control systems. This system is built using microprocessor controllers which were designed specifically for the automotive industry. Unlike a traditional Application Rate controller, the Multirate's computing power is distributed among several processors each controlling a specific part of the system. This translates into robust componentry, reduced wiring and faster response.
