P25 specification for high skid-resistant surfacings

High skid resistant surfacings (HSRS) are designed to be highly durable proprietary overlay treatments, usually applied to asphaltic or cementitious surfaces. Their purpose is to provide high skid resistance on the road's surface, at a specific location, over a long life. However, over the past decade in New Zealand, poor installation work and/or inappropriate underlying asphalt substrates on the state highway network precipitated the need to develop a performance-based specification. After significant research, planning and specification development, NZTA P25 Specification for High Skid-Resistant Surfacings has been finalised. P25 requires an HSRS to surpass, for at least the first 30 months, the specified level of skid resistance, material retention and adhesion to the substrate. Information about the installation and asset management of HSRS in a regional office is also provided.
