Improving the technology of laying asphalt concrete mix by introducing a special machine to increase the wear resistance and durability of coatings

Abstract

Highways are an integral part of our life, the number of cars increases annually, which requires the creation of high-quality asphalt concrete pavements, so the question arises about the modernization of the technology of laying the roadway. This article proposes the development of an innovative technology module for laying road surfaces, namely an asphalt concrete mixture loader, which will optimize the process of transporting the mixture from the dump truck body to the receiving hopper of the paver. The advantages and disadvantages of using asphalt concrete mix loaders used in the construction of different categories of highways are considered, the construction stages and processes arising with asphalt concrete mix are studied in detail. Calculations of the time of laying asphalt concrete pavements using traditional technology, as well as when using the designed loader, have been made. Comparative analysis has demonstrated the feasibility of technology that allows to improve the quality of the roadway.
