PRELIMINARY ACCEPTANCE CRITERIA FOR SOME ROAD DIMENSIONS

The dimensions include pavement levels, thickness, shape (crossfall and longitudinal grade), width, alignment, etc. The principal steps involved in reaching a fully implemented statistical specification are: a) evaluation of currently achievable dimensional variabilities, b) evaluation of statistical compliance schemes, c) preparation of model specifications. In this paper, the variability achieved in pavement surface levels as a function of the methods of process control which are normally adopted by the road authorities is briefly outlined. This dependence was found to embrace in a major way the effects of other factors such as the specified tolerances, machinery used for material placement, quality and intensity of supervision, material properties, etc. which can be expected to contribute to the achieved results. The paper also puts forward compliance procedures for discussion. As a first requirement, a sampling scheme based on cost and the required accuracy of the mean and variance is outlined from the engineering judgement point of view. Two approaches to acceptance criteria and their implications are briefly presented. /TRRL/
