SEMINAR D: INFLUENCE OF ROAD SURFACE CHARACTERISTICS ON VEHICLE RUNNING COSTS --PIARC XVIII WORLD ROAD CONGRESS, BRUSSELS, BELGIUM, SEPTEMBER 13-19, 1987
The first part of the report looks at recent research into some of the main elements of vehicle running costs: (1) fuel consumption (energy balance, effect of speed expressed in mathematical relations, role of cornering, influence of rolling resistance on fuel consumption on paved roads) and (2) tyre wear and damage (convoy testing, rubber loss mechanisms which can be identified as ridge and trough abrasion patterns, thermo-oxidation degradation, contact fatigue, abrasion due to rolling, grooving, chunking and flaking). Part 2 describes 4 studies of the effects of road condition on vehicle running costs and vehicle operating costs, carried out in Kenya, the caribbean, Brazil and India. The last part examines the best road surface compromise to achieve an appropriate balance for a particular road or runway, weighed against the whole life costs for the various material or method alternatives. For the covering abstracts of the congress see IRRD 812115 and 812116.
