Application of Basic Probability Theory in Pavement Quality Assessment by Layers Thickness

Abstract: When making road pavements, construction errors may occur. It determines the quality of conformance of finished product to the requirements of regulatory documents. Up to the present day theoretical and applied research is oriented to the assessment of impact of such deviations on road pavement behavior in operating period have not been conducted. The point is that the change of layer thickness affects both consumption of construction materials and strength of the whole road structure and, subsequently, its working efficiency, durability, repair size and time. The deviations can have a scope (a size) and a certain part in the total volume of a sample. Road pavement consists of various layers. The more number of layers is, the more combinations of deviations have been. In the present article we give the solution with the use of probability theory propositions. This solution, that became the base of a software product, lets evaluate the construction heterogeneity of a road pavement by the thickness of its layers. Key words: Probability theory Road pavement Quality of roadwork INTRODUCTION these deviations through the layers will make it It is common knowledge that one can ensure the high (constructional) strength heterogeneity in models of level of support and roadwork quality control relying non-rigid pavement behavior forecasting and residual only on the statistical method of describing properties life assessment. In the long run, such solutions wil
