MIT-SCAN2-BT Dowel Bar Scanner – Reliable Non-Destructive Dowel Position Testing

The MIT-SCAN2-BT Dowel Bar Scanner is a state-of-the-art non-destructive testing (NDT) system for accurately measuring dowel and tie bar positions in concrete pavements. Designed for use on highways, airport runways, container yards, and other large-scale concrete projects, it ensures proper embedment, alignment, and spacing — critical for load transfer, joint performance, and long-term durability.

With a compact rail-guided measuring trolley and a robust fiber-reinforced rail system, this scanner uses pulse-induction magnetic imaging technology to detect dowel bars embedded under the pavement surface, even immediately after concrete curing when the surface is walkable. The device wirelessly communicates with a Pocket PC, logs data in real time, and generates detailed maps and reports, making quality control straightforward and efficient.

Whether for fresh pavement quality assurance, acceptance by road authorities, or forensic investigation of existing slab issues, MIT-SCAN2-BT delivers rapid, repeatable, and highly accurate results — all without damaging the pavement.

Key Features

• Non-destructive testing: No coring or destructive methods — preserves pavement integrity.

• Pulse-induction magnetic imaging: Precisely detects dowel position, embedment depth, misalignment (tilt, shift), and presence of bars in baskets.

• Rapid measurement & analysis: Each joint inspection and evaluation can be completed in less than a minute; enabling hundreds of joints per day.

• On-site real-time results: Instant visualization on Pocket PC and downloadable Excel/PDF reports with 2D/3D mapping via analysis software.

• User-friendly, portable system: Compact measuring trolley, rail system, wireless communication — easy to transport, assemble, and operate on field.

• Meets standards: Compliant with ASTM E3013/E3013M and widely accepted by road authorities for concrete pavement acceptance and quality control.

Applications

• Quality control during concrete pavement construction (highways, airport runways, container yards)

• Acceptance testing by road authorities and contractors

• Inspection of dowel alignment after installation of dowel bar inserters (DBI)

• Forensic evaluation of existing concrete pavements if joint failure or slab faulting is suspected

• Large-scale infrastructure projects needing rapid, non-destructive verification of dowel placement
