The Traffic Speed Deflectometer measures the velocity of deflection rather than displacement. Measuring of the pavement response is based on advanced Doppler laser technique.
The measurement equipment is placed in the trailer and is connected with the truck, where the operator can monitor sensors and add events to the data.
Staff Requirement: 1 truck driver and 1 TSD operator. The operator controls data collection from the truck. No persons are present in the trailer during operation.
The measured data makes it possible to report deflection characteristics continuously. Collected data are treated in a dedicated post processing software program.
It is possible to combine the Traffic Speed Deflectometer with other Greenwood road measuring equipment’s. Such an equipment can take advantage of all the features in the Greenwood multifunction hardware and software package, where it is possible to measure and see all subsystems in a synchronized way both when collecting data and during post processing.
