TDRI Trailer System Scanning Road Segment

Network Scan

High speed, multi-directional scanning that captures network moisture data at scale.

You'll be able to:

Identify unknown and high risk moisture areas in your network

Reduce rework by using moisture data to inform root causes of deterioration and the correct treatments to execute

Justify and challenge investments by prioritising works based on the presence and severity of moisture

Transition from reactive to preventative drainage and sealing treatments that extend pavement life and reduce costs

Assess effectiveness of maintenance treatments with verifying moisture data

Best for State Highway & District Council Networks

Segment Scan

Scanning that captures road segments with high detail, accuracy and cross-sectional coverage.

You'll be able to:

Control quality during construction by monitoring optimum compaction and moisture content across full road extents

Verify an optimal moisture state of entire site post construction for contractual alignment and handover

Investigate extent of existing / residual moisture issues to determine root cause and inform correct course of action

Verify effectiveness of rehab or remedial works

Moisture Matters

Increased water content in a road pavement structure reduces its bearing and increases its degradation under traffic loading.

What research has found:

Road deterioration can occur 2.5x faster when increased moisture is present¹

For pavements with increased moisture, an estimated 12-30% of road maintenance cost savings can be achieved with proactive sub-surface moisture detection²

How Our Technology Measures Moisture

Click to dive into the details

We’ve developed a novel trailer system that advances the application of Time Domain Reflectometry (TDR) technology.

This breakthrough system has a configuration of sensor transmission rods that sit parallel and adjacent to the road surface, allowing for high speed, continuous and non-invasive measurement of the subsurface material. In comparison, legacy TDR systems have typically come in the form of handheld probes used invasively to measure target material.

The TDR measurement method directly detects a material's dielectric constant, which is a measure of how well that material absorbs electromagnetic radiation. The more water the material contains, the higher its dielectric constant.

Our system does this by propagating an electromagnetic pulse down the transmission rods and through the target material. The pulses time to return is directly related to the dielectric constant, and therefore moisture content of the material.

The system captures 5-20 samples per second at 1200mm width down to 250mm depth.

What our clients are saying

“Fulton Hogan is excited that this latest data will support works prioritisation, decision making and development of targeted outcomes with clients. Collecting moisture content of an entire network at high speed without disruption is a real advantage over previous test pit / lab test techniques.

We’re aligning our previous maintenance activities with the moisture readings to understand what methods and treatments are best at reducing moisture within the surface and pavement layers. Proving what works well in each region also provides us support for future maintenance activities.”
