摘要

这篇文章是关于国家交通大学公路和机场实验室的研究和开发工作的成果,即在现有的测量路面车辙(横向粗糙度)的装置的基础上,开发了一个用于评估基层和路面不平整度的微型水平仪的实验样品。给出了该装置的总体外观、主要技术特点和工作算法。在自然条件下,通过在沥青混凝土路面表面进行与传统设计水平平行的控制测量来测试该装置的性能。在国家运输大学的范围内,进行了一系列实验研究,使用已知的长度度量,作为参考。在乌克兰道路工业的实践中进一步研究和实施文章中所述的设备,将能够迅速监测路面和涂料的施工和维修,并在技术过程中进行纠正,有目的地管理质量,评估正在使用的路面和涂料的状况,并确定不令人满意的路面局部路段。这反过来将有助于减少与道路状况不理想有关的交通事故。同时,在批量生产的条件下,国内用于评价道路服基层和覆盖物不平整度的微型水平仪的成本可能比国外同类产品低几十倍。

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