The criteria are presented for the choice of the proper instruments to detect strains/ stresses and temperatures on a stretch of composite concrete motorway paving. The following are described: project, implementation and assembly of the entire acquisition system broken down in two parts. The first is designed for controlling low scanning temperatures to detect temperatures and strains due to thermohydrometric effects; the second for the dynamic control strains and vibrations induced by transiting vehicles. A few sets of data acquired are shown, along with subsequent processing. The system has made it possible: - to check project hypotheses on the operation of the concrete road superstructure. to check in time some of the characteristics assumed.
