Unsealed roads are a vital part of many rural, agricultural, and semi-urban communities across Queensland. However, without regular maintenance, these roads can quickly become hazardous, inefficient, and costly to repair. Road grading is one of the most effective ways to maintain and restore the condition of gravel or dirt roads—but knowing when to grade is just as important as knowing how.
At Stanthorpe Asphalt & Bitumen Surfacing in Stanthorpe, QLD, we specialise in delivering professional road grading services that enhance safety, prolong road life, and support uninterrupted access across all types of properties. In this article, we’ll explore the key signs that indicate when road grading is necessary, and why timely intervention matters.
What Is Road Grading?
Road grading involves reshaping the surface of an unsealed road using a motor grader or similar equipment. The process levels out uneven surfaces, restores proper drainage flow, and re-establishes the road’s camber (crown) to ensure water runs off instead of pooling.
Grading is essential for maintaining structural integrity, driving comfort, and accessibility—especially in high-use or weather-affected areas.
Signs That Road Grading Is Due
Over time, even well-built unsealed roads will show signs of wear and damage. Acting on these early signs can prevent more severe degradation and costly repairs down the line.
1. Corrugations and Rippled Surfaces
Also known as “washboarding”, this occurs when the road surface develops evenly spaced ripples, making driving uncomfortable and damaging to vehicles.
- Caused by repeated wheel impact and poor moisture levels
- Creates vibrations that reduce control and increase tyre wear
- Significantly affects driveability and safety
If corrugation appears along sections of your road, it’s time for grading to restore a smooth, stable surface.
2. Potholes and Surface Depressions
Potholes are more than just a nuisance—they are a symptom of a failing surface structure. Left unattended, they spread quickly, especially after rainfall.
- Water infiltrates and weakens the road base
- Vehicles worsen the damage by compacting edges
- Increases the risk of vehicle damage or injury
Prompt grading can eliminate shallow potholes and restore surface uniformity before more invasive repairs are needed.
3. Poor Drainage and Water Pooling
Proper drainage is one of the most critical aspects of an unsealed road. If you see water sitting on or beside the road, it’s a red flag.
- Indicates the road crown is flattened or eroded
- Pooling accelerates erosion and softens the base
- Can lead to ruts, scouring, and eventual surface collapse
Grading re-establishes the crown and promotes run-off, preventing long-term water-related damage.
4. Ruts and Wheel Tracks
Deep wheel ruts develop when traffic repeatedly travels the same path, compacting certain areas while loosening others.
- Reduces road clearance for vehicles
- Channels water along tracks, worsening erosion
- Dangerous for smaller vehicles and trailers
In Stanthorpe’s mixed-use rural areas, rutted roads can quickly become inaccessible during wet conditions—making timely grading essential.
5. Dust and Loose Material
If dust clouds follow every vehicle or if loose gravel is building up along the shoulders, it’s a sign the surface has lost cohesion.
- Indicates surface materials are drying out and shifting
- Leads to air quality issues and reduced traction
- Affects visibility and driving conditions
Grading helps reincorporate loose material into the road surface and improve dust suppression.
How Often Should Grading Be Carried Out?
There is no one-size-fits-all schedule. The ideal frequency depends on:
- Traffic volume – Heavier use means faster wear
- Weather patterns – Frequent rain or drought can destabilise the surface
- Soil type and road base quality – Some materials hold up longer than others
- Drainage conditions – Roads with poor drainage degrade faster
