An assessment of the performance of different aggregates in delivering skid resistance

The delivery of a Skid Resistance strategy relies upon the appropriate selection of aggregates to provide different levels of skid resistance for different environments and site characteristics. In the United Kingdom the use of the Polished Stone Value (PSV) based on the recommendation in the Highway Agency standard HD36/06 is typically used to specify the PSV required for different site characteristics. Somerset County Council has a comprehensive record of surface treatments undertaken on their network including the specification and source of the material used. In seeking to ensure that their Materials policy was striking an appropriate balance between the cost of premium aggregates and the need to achieve defined investigatory levels a study was undertaken to explore how different aggregates performed. The study involved linking the SCRIM coefficients with the material type and source to assess how different aggregates performed in service after 2 -8 years trafficking. The results of the review have been used to refine the Somerset County Council materials policy, develop the balance between locally sourced and imported high PSV aggregate and to consider whether blends of different aggregate are acceptable.
