BITUMINOUS COMPOSITION USED FOR REPAIR OF WET ASPHALT-CONCRETE PAVEMENT

摘要

FIELD: construction industry.;SUBSTANCE: bituminous composition used for repair of wet asphalt-concrete pavement includes bitumen BND 60/90, diesel fuel as thinner, surface active agent KADEM-VT, and thermoplastic elastomer RTEP as an additional structure-forming component at the following component ratio, wt %: bitumen BND 60/90 - 78.0-87.0, diesel fuel as thinner - 10.7-17.8, surface active agent KADEM-VT - 0.3-0.7, structure-forming thermoplastic elastomer RTEP - 2.0-3.5.;EFFECT: strength increase of dry and water-saturated samples under the temperature of 20°C and 50°C, water resistance coefficient increase, and considerable decrease of cold mixes caking factor.;1 ex, 5 tbl
