摘要

the invention belongs to the field of u0430u0434u0433u0435u0437u0438u043eu043du043du044bu0445 additives used in road construction, the bituminous compositions. the task of the invention is the creation of asphalt coating with improved performance characteristics.the challenge is the fact that the bitumen based composition for road pavement, comprising bitumen and u0430u0434u0433u0435u0437u0438u043eu043du043du0443u044e additive - liquid u043fu043eu043bu0438u0431u0443u0442u0430u0434u0438u0435u043du043eu0432u044bu0439 rubber and hydrocarbon oil in the ratio of asphalt, rubber, oil u043fu043eu043bu0438u0431u0443u0442u0430u0434u0438u0435u043du043eu0432u044bu0439 from 94 to 96: 4: 2: 3: 1, according to the invention is used as a rubber u0432u044bu0441u043eu043au043eu043cu043eu043bu0435u043au0443u043bu044fu0440u043d one polymer with - u0441u0438u0437u043eu0441u0442u0440u043eu0435u043du0438u044f with molecular weight above 125000.as well as oil using low-temperature u043cu0430u043bu043eu0432u044fu0437u043au0438u0435 or u0440u0435u0433u0435u043du0435u0440u0438u0440u043eu0432u0430u043du043du044bu0435 mineral oil and further u0430u043du0442u0438u043eu043au0438u0441u043bu0438u0442u0435u043bu044cu043du0443u044e u043fu0440u0438u0441u0430u0434u043au0443 next to on the components of iau.%, u0432u044bu0441u043eu043au043eu043cu043eu043bu0435u043au0443u043bu044fu0440u043du044bu0439 polymer with - c2 - 4; u0430u043du0442u0438u043eu043au0438u0441u043bu0438u0442u0435u043bu044cu043du0430u044f list of gasoline additives 0.05 - 0.2; mineral oil - the rest; where according to the invention u0430u0434u0433u0435u0437u0438u043eu043du043d gear additive used in proportion to the u0431u0438u0442u0443u043cu0443 bitumen: supplement 1: 0.002, 0.005.the essence of the composition is that the use of the proposed additions to the u0431u0438u0442u0443u043cu0443 through molten polymer polyol esters with u0441u0438u0437u043eu0441u0442u0440u043eu0435 in u043cu0430u043bu043eu0432u044fu0437u043au043eu043c of u0443u0433u043bu0435u0432u043eu0434u043eu0440u043eu0434u043du043eu043c oil when performing the function of a binder and u0430u0434u0433u0435u0437u0438u043eu043du043du043eu0433u043e agent improves the compatibility with the bitumen, and the composition can t be used for lime, and u0441u0438u043bu0438u043au0430u0442u043du043eu0439 breed.
