MAINTENANCE OF PAVED ROADS. CURRENT STATE OF KNOWLEDGE AND RESEARCH NEEDED

UNDERHAALL AV BELAGDA VAEGAR. KUNSKAPSLAEGE OCH FOU-BEHOV

In Sweden, about one billion sek is spent annually on the maintenance of road and street pavements. To be able to use these resources in the best way, thorough knowledge of the consequences of various maintenance strategies is required. This bulletin surveys the need for research in this field. The most urgent research tasks are considered to be the following: (1) methods/models for predicting long-term changes in pavement condition when implementing various surfacing strategies; (2) efficient methods for determining the structural condition (bearing capacity) of roads; (3) measurement of current traffic loads and prognosis of future traffic loads (especially axle loads); (4) the influence of surface condition on vehicle wear; (5) the influence of surface condition on road accidents. However, present know-how is sufficient to initiate the development of planning systems for socially economic optimization of pavement maintenance. It is important that the planning systems have a flexible structure so that the newer and more reliable techniques expected from future research can be successively introduced. The planning systems must therefore be developed in close consultation between road authorities and research. (Author/TRRL)
