The author outlines the responsibilities for road maintenance in England, and discusses the widely differing costs incurred in various parts of the country, giving some reasons for the disparity. He explains technological developments used to help in analytical decision making, such as computerized assessment rating and treatment, the use of the Sideways Force Coefficient Routine Investigation machine to assess skid resistance, the use of the Deflectograph to assess structural stability of pavements and thickness of overlay needed; and the use of the Contactless High Speed Profilometer to obtain the profile of pavements. He outlines the United Kingdom's current approach to assessing the general trend of the conditions of the country's roads, with a view to achieving a more cost-effective approach towards maintenance. A "maintenance options study" and intervention levels for maintenance are outlined, and a pavement maintenance optimization model explained, which takes into account local characteristics and traffic loading.
