ESTIMATION OF LIFE CYCLE COSTS OF PAVEMENTS --BEARING CAPACITY OF ROADS AND AIRFIELDS. PROCEEDINGS OF THE 2ND INTERNATIONAL CONFERENCE, PLYMOUTH, ENGLAND, SEPTEMBER 16-18, 1986

Analytical methods are required to examine the effect of changes in maintenance funding on pavement condition. This paper describes a computer model and its use to forecast the gradual deterioration of pavement condition under traffic and estimate the cost of applying the maintenance treatments needed to maintain defined standards. Both the direct cost of maintenance works and the cost of traffic delays are examined. The model can be used to study different design and maintenance policies for both new and existing roads. An example is given of the cost over 50 years of maintenance works on a two lane dual carriageway. The effect of the cost of maintenance treatments on the choice of pavement design life is discussed. The cost of scheduling maintenance treatments as soon as intervention levels are reached is compared with a more practical policy of looking ahead when maintenance is needed and bringing forward any major strengthening treatment that is required in the near future. Alternatively a lesser maintenance treatment may be deferred until the major strenthening is due. The potential benefits of using surface dressing to preserve the condition of a road in need of strengthening are examined over evaluation periods commencing at the time of initial pavement construction and at the time of first strengthening.(a) for the covering abstract of the conference see IRRD 815528.
