ASSESSMENT OF THE GEOMETRIC PARAMETERS OF THE ROAD USING A MOBILE ROAD LABORATORY

Abstract

The relevance of the study is due to the fact that any complex laboratory equipment requires the appropriate qualifications of staff. A successfully mastered operator training course is sufficient for most standard situations, but does not provide comprehensive ideas about the features of the equipment and software in difficult field conditions, which in turn can cause difficulties in the operation of the device and an increase in the share of subjective decisions in the result. A more complete study of the operation of complex equipment is possible only having practical experience in its operation in different conditions. This article reveals the features of the Geometry complex of the mobile road laboratory KP-514 SMP Highway, which is used to determine the parameters of geometric characteristics, evenness of the coating, the strength of the pavement, and so on. The leading approach to the study of this problem is a descriptive method, which allowed to identify the features of the geometric characteristics of the road. The authors studied in detail the transport interchange on 73 km of the A-290 Novorossiysk - Kerch Strait highway. During the study, it was found that the Geometry module is sufficient to confirm safe traffic conditions and restore lost information about the geometry of the road, since information on the presence and parameters of transition curves is not contained in the description of the route plan. In addition, the authors came to the conclusion that the software settings affect the accuracy of processing the initial path and adjust it using the “comparison interval” parameter of the “setup” window of the Road-PRO software and measuring complex. The materials of the article imply practical significance for university professors in engineering specialties.
