Information × Registration Number 0208U006885, 0108U004929 , R & D reports Title To develop definition method for motorway sections decreasing the bearing strength in a certain estimated period. popup.stage_title Head Kushnir A., Registration Date 22-12-2008 Organization State Highway Scientific Research Institute popup.description2 Object of research is sections of roads with considerably decreased bearing ability of road constructions. The purpose of work is developing of definition techniques of sections with considerably decreased bearing ability during the predefined period. Methods of research are definition of characteristic sections, visual diagnostic study of destructions and deformations, elasticity measurement of bending flexure, elasticity modulus calculation for every section kilometer. Definition of elasticity modulus demanded, taking into account the traffic volume and intensity. The strength factor calculation, definition of sections demanded detailed diagnostic study, within application of the drilling equipment and the equipment for dynamic soils sounding. Soils sampling performed under pavement coating without baring procedure application. Analysed physic mechanical soils characteristics definition. Accurate definition of estimated elasticity modulus of roadbed soils after the results of field and laboratory trials. Measures aimed at reinforcement of bearing ability of road pavement are appointed. Those based on the analysis of gained results, and taking into account the revealed factors of decrease in this bearing ability.5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
