IMPROVEMENT OF GEODESIC METHODS FOR ROUGHNESS ASSESSMENT OF THE BASE AND PAVEMENT STRUCTURE

Serhiy Ignatov Natalia Neizvestna Dmytro Pavlyuk Borys Sevriuk Ivan Shuliak

The article is about the results of the research and development work of highways and airfields laboratory of the National Transport University, namely the development of an experimental sample of a microleveler for evaluating the unroughness of the base and road surface on the basis of an already existing device for measuring the rutting (transverse roughness) of the road surface. The general appearance, main technical characteristics and the algorithm for working with the device are given. The performance of the device was tested by conducting control measurements in parallel with a level of a traditional design on the surface of an asphalt concrete pavement under natural conditions. On the territory of the National Transport University, a series of experimental studies was carried out using known measures of length, accepted as reference ones. Further research and implementation of the device described in the article into the practice of the road industry in Ukraine will make it possible to quickly monitor the construction and repair of road surfaces and coatings and to make corrections in technological processes, to purposefully manage quality, to assess the condition of road surfaces and coatings that are in operation, and to identify local sections of roads with unsatisfactory levelness, which in turn will contribute to the reduction of road accidents associated with unsatisfactory road conditions. At the same time, it is expected that the cost of a domestic microleveler for evaluating the unroughness of the base and covering of road clothing may be several dozen times lower, compared to foreign analogues, under the condition of mass production
