Skid resistance is a critical factor in the safety and performance of any paved surface. Over time, asphalt surfaces can become smooth and polished due to traffic wear, reducing grip and increasing the risk of slipping or loss of control, particularly in wet conditions. In Stanthorpe, where surfaces are exposed to regular vehicle movement and changing weather, maintaining adequate skid resistance is essential.
At Stanthorpe Asphalt & Bitumen Surfacing, spray & seal is often used as an effective method for restoring and improving surface grip while also extending the life of the pavement.
How Skid Resistance Deteriorates Over Time
As asphalt ages, traffic gradually wears down the surface texture. Fine aggregates become embedded or worn away, leaving a smoother finish that offers less traction. Moisture further reduces grip by creating a thin film of water on the surface, making braking and steering less predictable.
These changes often occur gradually, meaning reduced skid resistance may go unnoticed until safety becomes a concern.
The Role of Spray & Seal in Surface Texture
Spray & seal works by applying a layer of bitumen followed by a carefully selected aggregate. This aggregate creates a textured surface that significantly improves grip by increasing surface roughness.
The result is a pavement with enhanced contact between tyres and the road surface, helping vehicles maintain better control during acceleration, braking, and cornering.
Improved Performance in Wet Conditions
One of the key benefits of spray & seal is its performance in wet conditions. The textured aggregate allows water to disperse more effectively, reducing the likelihood of water sitting on the surface and interfering with tyre contact.
In Stanthorpe, where weather conditions can vary, this improved water dispersal helps maintain safer driving conditions during rainfall and periods of increased moisture.
Restoring Grip Without Full Resurfacing
Spray & seal is often used as a preventative or restorative treatment rather than a full surface replacement. It can significantly improve skid resistance on existing asphalt that remains structurally sound but has lost surface texture due to wear.
By addressing skid resistance early, surfaces can remain safer and functional without the need for more extensive interventions.
Supporting Long-Term Surface Performance
In addition to improving skid resistance, spray & seal helps protect the underlying asphalt from further wear and moisture penetration. This protective layer slows oxidation and surface degradation, contributing to more consistent performance over time.
Improved grip combined with surface protection makes spray & seal a practical solution for maintaining both safety and durability.
A Professional Spray & Seal Approach in Stanthorpe
Effective spray & seal outcomes depend on correct surface preparation, aggregate selection, and application techniques. Each site requires assessment to ensure the treatment suits the existing surface condition and usage demands.
At Stanthorpe Asphalt & Bitumen Surfacing, spray & seal is applied with a focus on improving safety, functionality, and long-term surface performance.
Conclusion
Spray & seal improves skid resistance by restoring surface texture, enhancing grip, and improving water dispersal. This makes it a valuable solution for maintaining safer, more reliable asphalt surfaces as they age.
