Brief description
The aim of the project is to develop an opto-acoustic measurement technology that can be used to record the structural condition parameters of roads non-destructively, extensively and economically. This should enable a significantly improved assessment of the road structure and a more precise forecast of the remaining service life.
The method is based on the targeted excitation of acoustic waves in the road structure using high-energy laser pulses and their subsequent measurement. By combining modern measurement technology, signal-processing methods and physical modeling, conclusions can be drawn about material properties and layer structures. This is supplemented by validation using established test procedures and integration into existing road maintenance management systems.
The methods developed enable a new quality of road infrastructure condition assessment. As a result, public clients and infrastructure operators benefit from more well-founded decisions regarding rehabilitation measures, a more efficient use of resources and an extended service life of traffic areas. In the long term, the process thus contributes to more sustainable and economical infrastructure development.
