Abstract. Take into the account climate and environmental conditions of this region are necessary during modern road construction technologies introduction in the Republic of Sakha (Yakutia). This region’s climate and environmental conditions in many ways are identified as extreme. First of all, it should be noted that Yakutia is the coldest region of the Russian Federation, its territory is completely located in the permafrost zone. At the constructional materials testing center of the Pacific National University, were executed experimental studies to develop technological regulations for the modified bituminous binder manufacturing intended for paving the Lena highway (Yakutsk – Never).

In this work, for the polymer-bitumen binder manufacturing, was used bitumen petroleum viscous for road building, grade BND 130/200. In the course of the research, the polymer-bitumen binders PBV 200 and PBV 300 with a brittle temperature not exceeding -35 °C and -40 °C with the thermoplastic elastomers SBS LG 502 (South Korea) and SBS R 30-00A (JSC «Voronezhsintezkauchuk») additives use the formula selecting problem were solved, as well as plasticizer – industrial oil I-40A. To optimize the composition of the binder and further improve its characteristics, it is proposed to use bitumen with increased content of maltene fractions and to include in its composition an adhesion additive of the amphoteric type DAD-1. The resulting polymer-bitumen binder is characterized by a wide performance range – an increased softening temperature and a low brittleness temperature, elasticity (ability to reversible deformations), high adhesion to various rocks. Achieving these goals will improve the asphalt concrete pavement quality and durability in difficult climatic conditions.
