Definitions are given of quality standard, quantity standard and productivity standard, in relation to road maintenance. Quality standard which is the minimum standard a road may have should be determined by a cost/benefit analysis, the maintenance costs and road traffic costs at the same level being optimised. Road traffic costs are difficult to estimate; some can be calculated reasonably accurately. For instance, it was found in Finland that 1-2 cm snow on the road increased fuel consumption of cars at 80 kph by 1.2-2 litres/100 km. The minimum quality standard is maintenance of the road in a trafficable state. The greater the traffic volume on a road, the better condition it must be maintained in. Quantity standard which is the amount of labour and material per year for a certain length of road or similar unit in order that the minimum quality standard should be ensured, is dependent on traffic volume, climate and location, structure and geometry of the road. Productivity standard is generally defined on the basis of work study. These three standards are applied in predicting when maintenance is needed and in estimating annual labour and material requirements. /TRRL/
