RESEARCH OF INFLUENCE OF MEASUREMENT SPOTS DISTANCEON VALUE OF REPRESENTATIVE PAVEMENT DEFLECTION

Abstract

Efficient roadway management requires knowledge of the structural capacity of the roadway or the load-bearing capacity of the pavement structure. In order to determine the existing conditions of the pavement structure and define appropriate intervention measures, it is necessary to determine relevant impact on surface of the pavement structure on homogeneous road section. The aim of study is to investigate influence of distance between measurement spots of deflection to the value of relevant deflection. Based on calculation of representative deflections, error values were obtained depending on range of deflection measurements spots and subsections length considered.The key question is whether it is possible to obtain qualitative and quantitative data on the basis of which the structural state of the overall network with acceptable error can be estimated by increasing distance between measurements spots.
