Study on the Effect of Butonal NX4190 Polymer Latex on the Properties of Bitumen Binder and Asphalt Concrete

This article deals with the results of the study on the effect of technological parameters of the Butonal NX4190 cationic polymer latex modification on the physical and mechanical properties of road bitumen and various types of hot dense asphalt concrete and crushed-mastic asphalt concrete. The modification technological parameters were the content of the modifier and the modification time. The modification temperature was constant. The optimal amount of polymer latex for modification was determined according to the criteria for improving the physical and mechanical properties of bitumen and asphalt concrete.
