High Friction Surfacing (HFS) is a specialized road treatment designed to improve skid resistance and reduce the likelihood of accidents, particularly in high-risk areas such as sharp bends, intersections, pedestrian crossings, and steep inclines.

From the Anti-Skid website, here are some key points about HFS:

What Is High Friction Surfacing?

High Friction Surfacing is a type of pavement treatment that uses durable aggregates—typically calcined bauxite—bonded to the surface using a strong resin binder. This dramatically increases the friction between the vehicle tires and the road surface.

Benefits:

• Improves road safety by significantly reducing stopping distances.

• Ideal for accident-prone areas like black spots, approaches to intersections, pedestrian crossings, and roundabouts.

• Durable and long-lasting, even under high traffic volumes.

• Compliant with Australian standards for road surfacing safety.

Applications:

• Black spots and hazardous curves

• Steep downhill gradients

• Intersections and approaches to traffic signals

• Pedestrian crossings and school zones

How It Works:

1. Surface preparation: The existing pavement is cleaned and dried.

2. Resin application: A polymer resin (like epoxy or MMA) is applied to the surface.

3. Aggregate broadcast: High-friction aggregate (such as calcined bauxite) is spread over the resin.

4. Curing: Once cured, the excess aggregate is removed, and the surface is ready for use.
