LONG-TERM PAVEMENT PERFORMANCE MONITORING OF A SWISS MOTORWAY

Within the scope of rehabilitating the heavily traveled Swiss motorway A1, in 1998 a long-term (10 years) in-situ measurement system was installed. This project is unique in Switzerland, as it allows the monitoring of vehicle weight (WIM) and frequency, as well as the measurement of vertical pavement deformations caused by a vehicle at different pavement depths.
