To maintain roads according to their purpose, it is required to inspect their state with appropriate tools. This subject will be covered by the colloquium on “Methods to Evaluate Road Constructions” next Tuesday, November 24, organized by the KIT Institute of Highway and Railroad Engineering (ISE) headed by Professor Ralf Roos.

It is not sufficient to analyze the surface of a road. Thorough examination must go into depth, i.e. cover the entire construction, the individual layers, and their mutual interaction. This is the only way to reliably evaluate a road construction and estimate its further development.

At the colloquium, representatives of the Federal Highway Research Institute will present the current situation and findings from large test series on a model road. Experts will discuss various methods to test road constructions in Germany and Switzerland. KIT scientists will present possibilities of evaluating in a non-destructive manner the loading capacity and stability of concrete and asphalt roads. The falling weight deflectometer (FWD) applied for this purpose can simulate a load of more than five tons. Five tons are the load generated by a wheel of an average truck axle.

The colloquium on Tuesday, November 24, at the Altes Bauingenieurgebäude (building 10.81) on KIT Campus South will start at 13 hrs and end at about 17 hrs. The interested public is welcome.
