The Assessment of Highway Maintainability Indicators

The methods of managing the information model of the road at the operation stage are presented. A comprehensive methodology for checking transport and operational indicators is shown. It allows to predict the condition of the road surface, to determine the probability of deformations and destruction during the operation of the road. A software module is presented for assessing the maintainability of the road, taking into account all key transport and operational indicators. Based on this module, one can calculate the real overhaul service life for certain sections of the road. In the algorithms of the developed program, data transmission at various stages of the life cycle is provided, the stage of creating a general data environment, interaction with the IFC attributes is laid. This approach ensures the interoperability of the information model of the road and allows to evaluate current condition and planned measures to eliminate construction flaws or defects formed during operation, which ensures the extension of the road service life. Popular rheological models have been investigated for predicting residual deformations of road clothing based on the analysis of various models of the soil behavior of nonlinear soil mechanics. It is revealed that the most adequate model is a model that uses the theory of hereditary creep, which takes into account the calculation of non -rigid road clothing, which is exposed to short-term load from moving cars. Some aspects of the maintainability of the road facility affecting the environmental and economic indicators of the environment are given.
