Abstract

This article considers the possibility of using the dispersed waste of asphalt-concrete plants, namely the dust-entrainment, which is formed during the drying and heating of inert materials and accumulates in special dust-collecting facilities. The material under investigation corresponds to a finely dispersed filler used for the production of asphalt concrete mixtures for a number of features. It has been established that substitution of up to 50% of the mineral powder with its own dust-entrainment allows obtaining asphalt-concrete mixtures satisfying the requirements for the sharply continental climate.

Highlights

Active improvement of the infrastructure of the Baikal region, opening of new tourist destinations and expansion of the main recreation base of Lake Baikal form high rates of development of the road industry of the Republic of Buryatia
Among the materials used in the road industry, the Republic of Buryatia possesses a sufficient quantity of quality stone raw materials, but predominantly silicic and igneous rocks, which are used as large and small fillers
Sedimentary rocks are produced in the region by deposits in the Zaigraevsky district during the production of asphalt-concrete mixtures

Summary

Introduction

Active improvement of the infrastructure of the Baikal region, opening of new tourist destinations and expansion of the main recreation base of Lake Baikal form high rates of development of the road industry of the Republic of Buryatia. In this connection, work is carried out on the construction, reconstruction and overhaul of the existing network of highways of the region. Sedimentary rocks (which are a source of raw materials for the production of the mineral powder necessary for creating asphalt binders) are produced in the region by deposits in the Zaigraevsky district during the production of asphalt-concrete mixtures. Dust is formed by the operation of the drying drum (at the inlet) and sieves on the mixer (screen) of the hot material elevator [1-3]
