The properties of fine-grained asphalt concrete and its modified by bio based epoxy rape oil (BERO) form were studied. Rapeseed oil epoxide (ROE) obtained from renewable and ecological raw materials, rapeseed oil in a composition with initiators (hardeners) was used as a modifier. It was found that the introduction of BERO in the amount of 3% of the mass. allows to increase indicators of limit of durability of asphalt concrete at compression at a temperature of 20 ° C and 50 ° C. The efficiency of BERO composition and its positive effect on physical and mechanical properties of asphalt concrete is established.
