Rutted channels hold water, raising hydroplaning risk sharply at highway speed. More than 40 percent of highway rutting passes the resurfacing threshold before anyone measures it. This guide covers how rutting forms and how to mill and overlay before it turns structural.
What Is Inside
- What rutting is, and how the wheel-path dip forms through each layer
- The 300 million dollar annual cost of rutting-related resurfacing and claims
- How AI measures rut depth to within 3 mm across every wheel path
- A severity matrix by rut depth, from preventive overlay to reconstruction
What Causes It
- Heavy channelised traffic compacting and displacing material below
- High temperatures letting hot asphalt shove sideways under load
- Weak base or sub-grade deforming under repeated load
- Poor mix design, where weak aggregate interlock lets asphalt deform
How AI Finds It
- Collect: dashcam on any vehicle or phone, GPS-tagged, no road closures
- Detect: rut depth measured across each wheel path automatically
- Locate: exact GPS and chainage per segment, with a depth profile attached
- Deliver: network report with rut-depth heat maps and cost estimates
Severity and What To Do
- Low, under 6 mm: barely visible wear with no pooling, routine monitoring
- Medium, 6 to 13 mm: visible depression with slight pooling, preventive overlay or micro-surfacing within 6 months
- High, 13 to 25 mm: deep channels with hydroplaning risk, mill and structural overlay within 60 days
- Critical, over 25 mm: severe deformation and shoving, full-depth reconstruction, immediate
Who It Is For
- Highway authorities and concessionaires
- Pavement engineers and asset managers
- Resurfacing contractors
Continuous rut-depth measurement lets agencies mill and overlay before the problem turns structural.
