Bulakh E. Improvement of estimation of durability and deformativnosti of road constructions

Dissertation is devoted the improvement of methods of evaluation of deformation pavements due to providing of the calculation loading at tests, increase of exactness, informing and productivity of measuring of parameters which characterize deformation of pavements. It is grounded parameters of construction of equipment for creation of loading at the static tests of stamps of pavements, which improves the accuracy of static tests due to the removal of influencing of bowl of bending of surface from the wheels of heavy technique on the results of tests and exception of temperature deformation construction of deflectometer under influence of sunlight. It is first developed the mathematical model of the dynamic loading of pavement, which takes into account not only first but also next shots and rebounds of shock-worker from surface. On its basis found out expedience and efficiency of application is proved, as the measured parameter for the evaluation of deformation of pavements by a dynamic method, accumulated sum of moving of shock-worker at motion of him upwards during series of shots on surface.
