Information × Registration Number 0207U008618, 0105U007896 , R & D reports Title Creation of the system of estimation of reliability and safe state of constructions of road pavement of highways of the common use popup.stage_title Head Gamelyаk I.P., Registration Date 17-12-2007 Organization Ukranian Transport University popup.description2 It is developed the general{common} technique of an estimation and maintenance of reliability of designs of road clothes of nonrigid type of highways at design stages, constructions and operation. For an estimation of design reliability and durability of designs of road clothes it is used corresponding{meeting} mathematical model. Даная the model considers factor of a stock by different criteria придельного conditions and heterogeneity of durability, деформативности and parameters of loading acting on a covering. For an estimation of reliability at a stage of construction factors of a variation of geometrical parameters of designs, characteristics of road-building materials and a ground of an earthen cloth are established{installed}. It is developed a technique of an estimation of operational reliability of designs of road clothes in view of roughness of a covering and dynamic action of vehicles at travel of a covering with roughnesses. On the basis of the lead researches it is created system of an estimation of reliability and a safe condition of designs of road clothes of highways of the general{common} using.
