Description
Summary:A portion of the lane reserved for slow vehicles on a motorway was totally rebuild of the A10 Motorway in the West of Paris. Four sections have been instrumented using classical strain gage sensors, placed at different depths within the pavement (subgrade, cement-treated subbase, and bituminous base) and temperature sensors. A fifth section is equipped with a more innovative instrumentation including geophones and temperature sensors, coupled with a remote data acquisition system. The purpose of this paper is to present the monitoring of these experimental sections since 2011. Strain gage measurements are used to develop a mechanical model of the pavement structure, to evaluate the modulus of the different pavement layers, as well as their evolution with time. The results confirm the good performance of the in-place recycled subbase. Geophones are very sensitive sensors measuring vertical displacement velocity. Different methods for the processing of these measurements are proposed in order to monitor pavement deflections and identify and classify truck silhouettes.
