During the 1990s, various categories of thin surfacing that have beneficial short-term properties were introduced into the United Kingdom. Because of these properties, thin asphalt surfacings have gained a substantial share of the surface course market in all parts of the UK network. The first of the thin asphalt surfacings laid in the UK are approaching their expected service lives. It is, therefore, appropriate to review the latest evidence on performance and update the earlier assumptions about the service life for these products. The findings from the monitoring are that thin surfacing systems can routinely be constructed successfully to provide a safe surfacing with adequate skid-resistance, texture and visual condition and that these properties are maintained in service. Therefore, the evidence supports the acceptance by the Highways Agency of these systems for use on trunk roads in England (A). For the covering abstract of the conference see ITRD E212343.
