The Swedish paved road network is, on a yearly basis, monitored by road surface testers in order to supply the road administration with objective condition data .The data is used to measure how well the decided road condition standard is achieved and in the road maintenance planning. The constant demand on the road administration to be more effective motivates the development of suitable and up to date indicators and tools. The management of roads and pavements is a very complex task and requires a comprehensive set of relevant indicators. The development is divided into three periods; 1987-2004, 2005-2009, 2010 and onward. This report covers the second period 2005-2009. The main principle in the development, covering this period has been to create new indicators by using already collected data that either on its own or in a combination forms the new indicator. Focus has been on indicating damage on low volume roads. The new indicators are edge deformation, distance between rut bottoms, rut area and rut width. Other indicators have also been developed to cover safety risks, localized roughness and calculated water area. From previously work macro texture indicated by MPD (Mean Profile Depth) is used to assess sections with risk for low friction at high speed and wet conditions.
