Purpose and goal

The objective of this project is to develop a contactless source for generating seismic surface waves in a pavement structure. The new source will enable rolling profiling measurements of modulus and thickness of asphalt or concrete by seismic surface waves. The goal is to perform continuous measurements of roads from a vehicle in normal speed.

Expected results and effects

The expected result means a new innovative tool for assessing the condition of pavements. The technology is directly applicable for assessing the quality and reliability of both new and existing road structures and therefore contribute to the sustainable development of quality, environment, safety, and productivity in the construction industry.

Planned approach and implementation

The project builds on the research group´s recent results on noncontact seismic measurements and are well defined to the development of a unique new source of contactless generation of surface waves. The project begins with numerical modeling and experiments in the laboratory to develop an effective seismic source within the frequency range of 10-30 kHz. The developed source will then be tested on real pavements in the field.
