MAINTENANCE COSTS: THE ROAD TO RUIN

In terms of national expense, vehicle operating costs can increase if roads are allowed to deteriorate. A recent empirical analysis has shown that vehicle type wear and maintenance on a well maintained surface can reduce operating costs by up to 15 percent compared with that on a poor surface. Calculations suggest that the rate of return on road maintenance is very high and can be greater than 100 per cent per year. Although the national road maintenance condition survey showed that the number of defects in Britain's roads is not increasing, it is thought that perhaps the extensive use of low-cost surface dressings rather than overlays is concealing the true road condition. A study of overlay strategies in the USA, based on the present serviceability index (psi), showed that a delayed rehabilitation method cost 60 per cent more than a frequent overlay strategy. The author suggests that government should ensure that greater consideration should be made of users' costs in making maintenance decisions. (TRRL)
