MIT-DOWEL-SCAN Dowel Bar Scanner

We proudly introduce MIT-DOWEL-SCAN the latest development in Non-Destructive determination of dowel and tie bar positions in plain concrete. The MIT-DOWEL-SCAN is a totally new device allowing the operator to measure and evaluate pavement joints in real-time without using a rail system. The device makes use of the magnetic properties of the dowel bar by recording its returned magnetic field via sensors.
• Without a rail system the MIT-DOWEL-SCAN completes testing quicker than the previous SCAN2-BT system.
• The entire unit is provided in a single transport case making it easier to move than the previous system.
• The new MIT-DOWEL-SCAN has 10 sensors and a laser to guide the unit along the joint with great accuracy & repeatability.
• Single person operation with a removable data collector that attaches to the scanning device.
• Easier transfer of field data to MagnoProof 5 with USB port on the data collector

Real Time Mapping with immediate results after completing the test

Quick Fast Testing. No rails to move from joint to joint

.

• The new MIT-DOWEL-SCAN has 10 sensors and a laser to guide the unit along the joint with great accuracy & repeatability.
• Single person operation with a removable data collector that attaches to the scanning device.
• Easier transfer of field data to MagnoProof 5 with USB port on the data collector

The measurement method is used for Quality Control self-monitoring and Quality Assurance for acceptance during construction.

Details are shown in German Standard ZTV Beton-StB 07, ASTM E3013/E3013M MIT-DOWEL-SCAN technology is required by many state DOT’s when dowel bar insertion is used.

Measurement and evaluation of dowel bar positions in a joint takes less than a minute. Dowel embedment depths, misalignments & translations are determined precisely. Can evaluate new and existing joints. Also basket joints can be evaluated if the shipping wires are cut.

Applications Include:

• Quality Control by Contractors for checking their installation process
• Highway construction of plain concrete pavements
• Quality Assurance by Owners for accepting completed facilities
• Plain Concrete runways, taxiways & ramps at airports
• Concrete Sea Container storage & staging areas in Port Facilities
• Forensic Investigations of failing joints in existing pavements

Features & Benefits are:

Rapid & efficient
• Comfortable new handling configuration
• Fast & easy assembly & disassembly for transport
• Clearly arranged display panel for easy operation
• Intuitive measuring procedure
• Calculation of dowel bar positions immediately after the measurement
• Measurement of a joint across several lanes within one minute up to 45 feet.
• Batch evaluation of a large number of joints per day
Cost-effective
• Increase quality
• Reduce costs
• Efficient measurement method with high daily output
• In-process paving adjustments of the DBI
• Automatic evaluation of data
Non-Destructive
• Signal recording by simply moving the device over the concrete pavement
• No concrete cores are required for calibration
Precise
• Accurate measurement of dowel and tie bar positions in concrete
• Precise determination of dowel embedment depths, alignments, & translations
• Objective & repeatable
Flexible
• Horizontal curves, super-elevations or cross slopes do not affect the device
• Can be used before and immediately after the cutting of the joint
• Wet pavement has no affect on the test results
• Measure as soon as a person can walk on the concrete
Sustainable
• Free of emissions
• Safe to humans, nature and environment

System Scope

MIT-DOWEL-SCAN is delivered as a complete system ready to use. The measuring vehicle is equipped with an operating unit, a laser unit, software package MagnoProof 5, manuals and a solid case. Calibrations are additional and sold per dowel & tie bar sizes. Training is available upon request.

MIT-MagnoProof 5 analysis software is part of the MIT-DOWEL-SCAN system. It is a new version that supports the evaluating the signals from the 10 sensors on the scanner. The main function is the evaluation of measurement data at the desktop PC. MagnoProof 5 functions at a glance:
1. Data transfer to desktop PC via USB within the software
2. Data organization into work folders for multiple project capability
3. Software automatically corrects erroneous data
4. Identifies potential causes of result interferences
5. Automatic evaluation of depth, alignment, & translations of dowel bar positions
6. Quantative results & Joint map are shown on a single screen
7. Reports as MS-Excel and PDF files
8. Joint map integrated into the MS-Excel spreadsheet – no more JPEG files
9. Batch processing of multiple joints with statistical analysis tables for each bar per joint
