GPR diagnostics, highway, non - rigid pavement, ground surface, reliability, operational condition, research, method, electrophysical properties


The article contains information on the study of the possibilities of introducing GPR technologies into the practice of road surveying. The prospects for the development of this scientific direction are also analyzed. The tasks that can be solved with the use of ground-penetrating radar equipment during the non - rigid pavement.

The main reasons preventing a more dynamic implementation of ground-penetrating radar technologies in the construction industry are considered in detail. The main reasons are: the difficulty of interpreting GPR data, the lack of an instrument base, the lack of a single complex of equipment and mathematical support for non - rigid pavement, which allows for guaranteed high-precision interpretation of the results of GPR surveys of non - rigid pavement and ground surfaces, and the absence of a regulatory framework that regulates the survey of highways with the use of ground-penetrating radars. Modeling of signal propagation in an environment with known electrophysical characteristics allows to determine the shape and amplitude of a complete signal, giving the possibility of correct interpretation of radargrams in order to determine the speed of signal propagation in the studied structures, electrophysical characteristics of structural materials of layers of non - rigid pavement, the interface of environments. To carry out experimental studies aimed at the development of methods of thickness measurement and defectoscopy of structural layers of non - rigid pavement, specialists of the Kharkiv national automobile and highway university use a set of geolocation equipment that uses ultra-broadband signals. A set of georadar equipment is used both for conducting experimental laboratory research of road clothing and for field surveys for the purpose of developing a road monitoring system using radar methods. For the verification and practical use of the proposed scheme for determining the time delay of signals, which allows to calculate the thickness of the structure under study, appropriate software was developed.

A series of laboratory experiments were conducted using this software product. As shown by the experimental laboratory studies, the method allows to restore the thickness of the layer under investigation with a fairly high accuracy.
