Brief description of MIT-SCAN2-BT

Nondestructive testing of dowel bar alignment in concrete pavement

 

MIT-SCAN-2 and MIT-SCAN2-BT were developed specifically for the evaluation of dowel bar alignment in concrete highways. The pulse induction method utilizes the magnetic properties of dowel bars to create a magnetic field. The resulting field -created by the metal bars- is recorded by a sensor field. The emission unit as well as the sensor field are placed inside a measuring carriage, which is pulled on a rail along the joint of a highway. The control of the measurement, the recording and the analysis of data are done by a Pocket PC, which communicates via Bluetooth connection with the measuring carriage. A more detailed analysis of the data can be done by the software MagnoProof on a desktop PC in the lab.
