High PSV Aggregates for Enhanced Skid Resistance and Road Performance

Engineered for High-Stress Sites Where Grip, Durability, and Compliance Matter Most

High Polished Stone Value (PSV) aggregates are essential for delivering high-performance, skid-resistant road surfaces. As traffic volumes increase and vehicle technology evolves, the importance of durable, high-friction surfacing materials has never been greater. High PSV aggregates help reduce road accidents, particularly in high-risk areas such as sharp bends, steep inclines, and heavy braking zones. Engineered to resist polishing under traffic, these premium aggregates maintain surface texture and grip over time — making them a top choice for road safety and infrastructure longevity.

High-PSV Benefits

Outstanding Skid Resistance

High PSV aggregates maintain critical surface texture, helping prevent skidding in wet and dry conditions — even after extended traffic exposure.

Improved Road Safety

Ideal for high-stress sites, these aggregates significantly reduce the risk of accidents by offering consistent traction, especially in high-speed or high-braking zones.

Long-Term Performance

High PSV materials resist polishing and maintain their microtexture, extending the lifespan of road surfacing and reducing the need for premature resurfacing.

Why use High PSV Aggregates?

The primary reason for using High PSV aggregates is their superior ability to maintain skid resistance, a key factor in preventing vehicle accidents. As tyres wear down aggregate surfaces over time, materials with low PSV polish smooth and lose grip, whereas high PSV aggregates retain a rough, micro-textured surface that continues to provide friction.

Skid resistance is measured using standardised tests like the Polished Stone Value (PSV) and SCRIM (Sideway-force Coefficient Routine Investigation Machine). PSV quantifies how resistant a surface aggregate is to polishing under real-world traffic conditions. In the UK, materials used on high-risk sites often require a PSV exceeding 60 psv on very high risk sites this could require premium aggregates exceeding 68 PSV.

Incorporating high PSV aggregates into surfacing design not only enhances vehicle braking efficiency but also ensures that the road network can handle modern traffic volumes without compromising on safety. Engineers and contractors rely on PSV data to make informed choices for both new construction and maintenance resurfacing.

Whether you're working on highways, urban infrastructure, or heavy-duty pavements, our range of high PSV aggregates is designed to meet and exceed UK and European standards. Improve your project's safety profile with aggregates proven to reduce skidding and enhance durability.
