Concrete Pavement Monitoring

Dynamic stresses and displacements with temperature and 3D orientation

Monitor vertical, transverse and longitudinal stresses, displacements and temperature in concrete pavement structures with our AST200-6 modules. The AST200-6 module has a uniaxial temperature compensated strain transducer with sub-microstrain resolution. Each module has a 3-Axis accelerometer with a 1500 HZ bandwidth and DC response for dynamic displacement measurements and long-term tilt changes.
