Zhukov O. Planning of bituminous concrete layers of wear for municipal streets and roads

Dissertation on the receipt of scientific degree of candidate of engineering sciences after speciality 05.22.11 - Roads and Aerodroms. - National transport university, Kyiv, 2011. The analysis of existent domestic and oversea approaches of construction of bituminous concrete layers of wear clothes of non-rigid type is conducted. On the basis of analysis of work of bituminous concrete layers of wear determined, that principal reasons of formation of cracks is a general action of horizontal stretchings tensions from fluctuations in a temperature which causes unintentional reduction of sizes at cooling, and action of horizontal stretchings tensions from a transport loading. The developed classification of the modes of a transport loading on the layers of wear of city streets and roads, and also analytical dependences, for the calculation of bituminous concrete layers of wear on longevity. Improved the method of calculation of bituminous concrete layers of wear on longevity of city streets and roads of taking into account influence of fluctuations in a temperature and duration of action of loading from transport vehicles. The developed method of experimental estimation of rut resistance of bituminous concrete layer of wear and estimation of his coupling with pavement. Experimentally investigational thermo-viscous resilient descriptions and indexes of longevity of bituminous concrete of layers of wear. Developed method of planning of bituminous concrete layers of wear in city terms and the application programs are developed for realization of engineering's calculations. The developed requirement to the probed compositions of materials of bituminous concrete layers of wear from point of increase of them temperature of crack resistance and from the action of transport vehicles. The developed recommendations and practical application of dissertation researches is carried out at planning of bituminous concrete layers of wear for city streets and roads, that allowed to promote their longevity and get an economic effect. The results of dissertation researches were inculcated at planning and construction of bituminous concrete layers of wear on the objects of Kyiv. Keywords: bituminous concrete layer of wear for city streets and roads, construction of road pavement, condition of longevity, crack resistance, measure of damaged of structure of bituminous concrete.
