Novakovskiy D. Improvement of quality control methods of pavement asphalt concrete layers construction

The object of research was a process of distribution of the wave fields, which arise up in the bituminous concrete layers of road construction under the action of impulsive loading. For the decision of the set tasks method sand devices for determination of physic and mechanic properties оf bituminous concrete layers in laboratory and field terms were used. For analysis of parameters of distribution of the wave fields, arising up under the action of test loading, the method of spectrology was applied. Experiments results were processed with use mathematic and statistical methods and PC. On the basis of theoretical and experimental studies dependence of parameters of distribution of the wave fields, which arise up under the action of the test impulsive loading, from deformation properties, density and thickness of asphalt concrete layer was received; the complex of equipment and method of non-destructive control deformation properties, density and thickness of asphalt concrete layer were developed. Scientific novelty. The validation of influence of deformation properties and thickness of asphalt concrete layer for parameters of distribution of the wave fields, which arise up under the action of the test impulsive loading, got further development. Dependences of distribution speed of shear wave from deformation properties, degree of compression and temperature of bituminous concrete layers of road construction were first set. Practical results. The method of non-destructive control of deformation properties and thickness of asphalt concrete layers was developed. For practical realization of quality control method of bituminous concrete layers a nequipment and software were worked out.
