Arsenieva N. Improvement of the method of calaulation of flexible pavenents based on the criterion of the strength of asphalt concrete layers shear

Оbject - laws of the stress-strain state of the asphalt layers covering non rigid pavements based on their thermoplastic properties; goal is to improve the method of calculating the non-rigid pavements introduction of additional criteria shear strength of asphalt coating layers according to their thermoplastic properties; the procedure theoretical and experimental study of the stress-strain state of asphalt coats, their strength characteristics, methods of mathematical statistics, results are compared with the generally recognized, proven solutions of the stress-strain state of a layered elastic half-space and, novelty - substantiates the use of strength criterion for Pisarenko-Lebedev evaluation of shear strength of asphalt layers coating based thermoplastic material properties obtained Refinements decision determining shear strength in consideration of additional adhesion forces (tensile strength (tensile)) as an additional shift of the resistance during the formation of surface displacement within the solid material substantiates determine the strength at break (tensile) test results for asphalt torsional practical results - set the limit on the strength of asphalt concrete uniaxial compressive and tensile depending on the time of loading and temperature asphalt for settlement criterion shear strength; the technique of determining the strength of asphalt concrete to break; reasonably defined and calculated load value, depending on traffic conditions; proposed to supplement the zoning of Ukraine in terms of asphalt concrete data on landslide-prone periods; developed methods of calculating the position of asphalt layers of non rigid pavements shear, introduction - regulatory and technological documents road sector, enterprises of the State Agency of Ukraine roads "Ukravtodor"; аpplications - design, construction, reconstruction of non-rigid pavement type on the network of public roads in Ukraine.
