AC700 Material Sensor

AC700 controller - feeder - conveyer

Improve mat quality

The material feed system of an asphalt paver has a big effect on mat quality.

A fluctuating level of asphalt material in front of the screed will affect the screed angle of attack and produce bumps in the finished mat.

Lack of sufficient material covering the augers can also lead to material segregation and a rough, low-density mat.

With the AC700 Material Control you create a controlled HMA flow path, so that quality and texture of the mat is the same the full width of the screed.

How it works

The AC700 use ultrasound to continuously monitor and regulate the flow of asphalt material to the screed to secure a constant and even distribution of material across its full length. It can be used for auger control, and to manage the material load of the conveyor belt.

The AC700 comes in two basic versions, a Material Controller operated directly from the unit, and a Material Sensor operated from the asphalt paver.  It exist in a variety of types to fit the specific output of different types of asphalt pavers. Which version and type you need depend on the requirement of the asphalt paver.



  • Remove bumps in the mat due to poor material management
  • Reduce segregation with constant auger speed
  • Get high material consistency across the mat
  • Non-contact system with no wear and tear
  • LED panel indicating functionality
  • High operating temperature of 85 °C

"We find that the AC700s are far superior to the material controllers that came with the machines"
