TOWARDS DURABILITY OF AUTOMOBILE ROADS

Evaluation of the durability of the road is a consistently relevant industry problem. The use of mathematical theory of reliability is due to the probabilistic nature of many factors affecting the duration of the effective service of road elements. The article presents the results of calculating the durability of road using the failure rate functions based on the exponential law, the Weibull law and the United law. The variants of calculation of durability considered in article, taking into account the called functions, provide rather objective assessment of indicators for highways with non-rigid type of road clothes. The calculation of the durability of the transport structure is made by a simple algorithm. The main difficulty in using this algorithm is the need for experimental determination of the parameters of the failure rate function, but this difficulty is typical for any statistical method. At the same time, among the factors affecting the variability of parameters should be identified geographical complex, individually characteristic of the region of study. Therefore, in the future, to determine the failure rate of the elements of the operated roads, it is necessary to create regional Bach data characterizing the technical condition of roads and their elements in accordance with industry regulators.
