Does friction and colour equal safety? [road surface treatments]

This paper introduces a discussion for: 1. identifying what makes a high friction surface treatment; 2. comparing natural quarried aggregates and calcined bauxite in terms of surface friction and polished stone values; 3. the type and durability of coloured surface treatments, and; 4. safety outcomes from the use of both materials in terms of friction and colour. Examples are described where: 1. the material has performed well above its specified requirements; 2. the use of inappropriate materials that have reduced the life of the treatment are discussed, in terms of failure mode describing the material properties and the reasons that led to the failure; 3. the benefits gained from using high friction and coloured surface treatments. The report concludes that when a properly designed and applied high friction or coloured surface treatment is used on a suitable road surface where there is a high incidence of congestion and crashes that an immediate reduction in crashes should be expected with a corresponding reduction in travel time.
