RESEARCH ON THE PARAMETERS AND CHARACTERISTICS OF ROAD EQUIPMENT FAILURES

The parameters and characteristics of failures of road equipment for road construction are investi-gated. Attention is paid to the main types of distribution of equipment operation time to failure on the basis of exponential, Weibull, gamma, normal and logarithmically normal. Thus, the logarithmic normal distribution is used when the development of the process leading to failure can be represent-ed as the product of successive independent random variables (for example, crack growth). that the uptime and useful life of the technique depend on a large number of factors, some of which are be-yond control and others are established with a certain degree of uncertainty. The systems of machine maintenance and the laws of distribution of operating time for failure and the duration of failure elimination are considered. The influence of parameters on ensuring the effective use of equipment in the formation of a construction project is determined.
