Abstract
A new sensing solution based on the combination of a technical geotextile and fibre optics measurement technologies has been developed for strain and temperature measurement in pavement. This monitoring system has been evaluated in the laboratory with a 4-points fatigue device. Our results show a very high sensitiveness of the sensor enabled geotextile to be able to detect strain smaller than 10 micro-strain and fast dynamic movements with frequencies up to 1000 Hz. Installation trials have been carried out in different locations with conventional road paving equipment, in both asphalt and concrete pavement applications. The response of this sensing solution to traffic loads is very good and makes of this technology a powerful tool for road ageing assessment, analysis and maintenance.
