Benkelman Beam
The Benkelman Beam enables precise and non-destructive measurements of the load-bearing capacity of road surface layers made of asphalt or pavement. In the case of concrete road surface pavements, movements of the slab edges can be measured in order to draw conclusions about the lateral force transmission in the area of the joints.
Fields of Application
In conjunction with additional tests, the Benkelman Beam is used to determine the load-bearing capacity of roads for
- Identification of visually undetectable weak points
- Formation of homogeneous roads sections with comparable load-bearing capacity
- Recording of load-bearing behavior over longer periods and after extreme hydrological events
- Identification of structural causes of damage and assessment of structural condition
- Selection of appropriate road maintenance measures
