Abstract
The paper considers the advantages and nature of georadar monitoring of road surfaces comparing to traditional destructive methods of road exploration. The authors checked the thickness of the structural layers of pavement to determine appropriate repair work using the amplitude-frequency characteristics and the dielectric constant (the speed of signal transmission). The article examined the section of the highway and the examination data was recorded in a file, which allows further study and documentation of the material with the help of computer equipment.
Highlights
The purpose of the study is to increase the effectiveness of the application of georadar equipment for flaw detection of the pavement
The task of the study was to check the thickness of constructive layers of pavement for the purpose of assigning appropriate repair work, if necessary
Designation of the appropriate type of repair work will allow to extend the life of the pavement
Summary
The purpose of the study is to increase the effectiveness of the application of georadar equipment for flaw detection of the pavement. During one session you can record profiles for several hundred kilometers long. Depending on the complexity of the geological conditions, one operator processes from 3 to 10 km of the recorded profile during a working day. During the road construction works, the compliance of the executed works with the approved project documentation, technical regulations and standards is estimated [13, 14]. When assessing the thickness of paved bituminous concrete, the common practice is core sampling, measurement of their thickness and laboratory tests for determination of density, compaction factor and water saturation
