MIT Dowel Bar Scanner

Civil Tech determine the quality of Concrete Pavement joints by using MIT SCAN 2BT Dowel Bar Scanner.  The MIT-SCAN2-BT sensor system provides nondestructive testing of dowel bars in plain concrete pavements. It is used to measure the Length Position and Direction of Bars in Concrete Pavement. Multiple sensors and innovative data interpretation software make the device extremely accurate. MIT SCAN 2BT Dowel Bar Scanner is used to measure the Length Position and Direction of Bars in Concrete Pavement.

Joints in concrete pavements of highways, airport runways and container areas are exposed to stresses and strains due to traffic and temperature variation. Steel dowel bars and tiebars are built into joints, to support the transfer of loads across the joints and and to maintain the elevation of adjacent slabs at the joints. The type and the number of dowels and tiebars as well as their accurate positions and tolerable displacements are accurately determined, to ensure the long-term performance of the joints.

 

• Specialized system for the measurement of dowel bar and tiebar positions (including bars in dowel baskets).
• Easy handling, assembly and transport. Accurate and fast non-destructive measurement of dowel positions.
• High precision: Depth and misalignments of bars can be determined with a tolerance of ± 4 mm, side shift with a tolerance of ± 8 mm (peak to peak).
• Since 2001, A new standard for the non-destructive measurement of dowel bars has been achieved with the measurement system MIT-SCAN-2. Also international partners rely on the accuracy of the system. Several States in the USA and Provinces in Canada specify the use of the measurement system for the operation of dowel bar inserters.

Specification

• MIT-SCAN2-BT consists of a compact rail-guided measuring device, an easily assembled GRP.
• It has rail system and a Pocket PC for ease during testing and for data collection process.
• The Pocket PC communicates with the measuring device via a Bluetooth connection.
• The software MagnoNorm, that runs on the Pocket PC, controls the action of the device.
• The measurement data can be automatically recorded, reviewed and analyzed on-site. The software MagnoProof has been created for a more detailed data evaluation and the creation of reports on a Desktop PC.
