Crack formation is presently considered as an actual problem in the global practice. The paper provides various approaches pertaining to improvement of asphalt-concrete composition with the purpose to prevent formation of temperature and fatigue cracks and develop design and technology measures for avoidance of reflection cracking in asphalt-concrete strengthening layers. However there is no comprehensive solution of the problem that combines a material science and affirmative approaches. Existing technology for crack sealing in roadway covering is rather efficient at the stage of its operation and makes it possible to eliminate cracks depending on their nature and opening width but there is no efficient diagnostic and control system for preventing cracks with opening width up to1 mmwith the purpose to exclude their further development.

Highway slipperiness is one of the most dangerous meteorological phenomena for traffic participants. Exclusion of glazed frost formation can be only achieved on the basis of slipperiness forecasting. Winter slipperiness forecasting is rather complicated problem due to a lot of influencing factors and their non- deterministic character. Various types of winter slipperiness and specific forecasting features of this phenomenon are thoroughly considered in the paper. Forecasting methods for some highways and their sections are mainly statistical at the present moment. They are based on processing of a great number of empiric data. The paper proposes an empiric model for forecasting temperature pavement according to ambient temperature, humidity, wind direction and presence of vegetation along a highway. The obtained model can be used to forecast slipperiness formation during winter highway operation.
