HOW DESIGN, CONSTRUCTION AND MAINTENANCE INTER-RELATIONSHIPS AFFECT TOTAL LIFE PERFORMANCE OF ROADS . 15TH ARRB CONFERENCE, DARWIN, NORTHERN TERRITORY, 26-31 AUGUST 1990; PROCEEDINGS PARTS 1 TO 7

The costs of a road project over its service life are a function of the design, quality of construction, maintenance strategies and maintenance operations. These control the rate at which the road deteriorates and in effect dictate the maintenance workload throughout the life of the road. There has been very little work on the inter-relationship of the above components of a road project. Using one of the computer cost models available for developing countries, RTIM 2, developed by the Overseas Unit of the Transport Road Research Laboratory, UK, the total life economic significance of varying the above relationships is highlighted for a road project in Africa. Variables evaluated are geometrics, pavement design methods, 'as constructed' versus 'as designed', various specified quality levels of construction, and maintenance strategies/capabilities. Although there are weaknesses in the use and application of computerised models such as RTIM 2, they are probably the best application of the total life cost concept. (Author/TRRL)
