Dowel Bar Scanner (Walking Type)

Dowel Bar Scanner – Walking Type (Laser-Guided)

The Dowel Bar Scanner (Walking Type) is a laser-guided, rail-independent non-destructive testing device for rapid on-site assessment of dowel bar position, depth, tilt, and lateral shift in concrete pavement joints. Unlike the rail-guided SCAN2-BT, this walking system requires no track setup, making it faster to deploy on live highway projects.

Key Advantages Over Rail-Guided Systems

• No track assembly required — scan a joint in under 3 minutes
• Laser guidance ensures precise, straight-line scanning path
• Real-time on-screen display of each dowel bar position as you scan
• Detects depth of cover, lateral offset, tilt in both planes
• Ruggedised field housing for Indian highway site conditions
• Data exported directly to reporting software

How It Works

The operator walks the scanner across the pavement joint along the laser-defined path. Internal electromagnetic sensors detect individual dowel bars and record positional data. Results are displayed instantly on the integrated screen and stored for reporting.

Applications

• PQC (Pavement Quality Concrete) highway projects under NHAI, state PWDs
• Runway and taxiway construction QA/QC
• On-the-spot acceptance testing where speed is priority
• Pavement research and forensic investigations

Standards

Compliant with ASTM E1742, EN 12697-47, IRC:SP:62.
