DEVELOPMENT OF A METHODICAL APPROACH TO THE MAINTENANCE OF HIGHWAYS IN THE WINTER PERIOD TAKING INTO ACCOUNT WORLDWIDE EXPERIENCE

Anatolii Smirnov

The article examines models and proposes a methodical approach to highway maintenance in the winter period, taking into account world experience. It was determined that the assessment of winter road maintenance measures performed in different countries takes different forms according to: quality indicator or standard; cost accounting and analysis; organized management system; standards for inspection and monitoring of works; measurement of conformity of service provision; analysis of complaints from users of the road network; methods of forecasting and prevention of certain winter phenomena. It is proposed to use the WSI (FHWA) index, which is calculated on the basis of the average value of daily snowfall and the recorded minimum and maximum temperature on average for the season, to assess the severity of the impact of weather on winter maintenance. It is recommended that the results of precipitation forecasting and the level of the WSI index be used as a basis for determining the operational level of service, which forms a set of potential measures for winter road maintenance. It is proposed to justify the level of service based on models of winter maintenance and forecasting measures that allow to form a methodical approach to highway maintenance. A methodological approach has been developed, which is based on the use of a mathematical model of road maintenance in the winter period, which is a function of minimizing the accumulated indicators of the quality of winter maintenance of road elements depending on their weight for maintenance
