Research of Road Pavement Survey Process Using Georadiolocation

Abstract

The authors of this paper carried out a survey of road pavement and analyzed the need for such survey. The research was conducted using an operating facility as an example. In this paper, the decisions are grounded, the survey stages are described. Mobile methods of non-destructive control for road structures diagnostics are of particular importance at the moment. As a part of this research, the tasks related to determining the thickness of structural layers, the uniformity of materials, and the detection of voids under the auto-road surfacing were solved. The results of diagnostics and quality control of road-building works, as well as georadiolocation (GPR) technologies, are considered in detail. The results of tests of different GPR models and the economic efficiency of their use in road industry are described. The test results are illustrated with radarograms. The result of the GPR study of an auto-road section is presented. The results of the work showed that GPR research methods as a part of the survey allow reasonably planning and carrying out measures to eliminate and prevent various types of subsidence and road surfacing destruction, as well as to assess the nature and extent of the negative processes development. With the timely elimination of these problems, major damage and subsequent costly repairs can be avoided. Having compared the most significant factors, the authors make the conclusion that the method under research has got advantages, which are high efficiency and high capacity.
