Construction of an experimental section of asphalt concrete pavement using zeolite
Incoming article date: 09.11.2024The increase in the length of asphalt concrete roads increases the importance of efficient asphalt concrete plants in road construction. Modern environmental requirements and rising fuel prices determine a decrease in the temperatures of cooking and laying ABS. In foreign and domestic practice of road construction, warm asphalt concrete mixtures are increasingly used, including with the use of zeolite. The prerequisites for the study of warm asphalt concrete using zeolite in the Republic of Tatarstan is the presence of one of the largest deposits of zeolite-containing rocks of the Russian Federation - Tatarsko-Shatrashansky. Pilot production implementation of the research results was carried out during the construction of an experimental section on the highway – the entrance to the locality of Klyuchishchi in the Verkhneuslonsky district of the Republic of Tatarstan with an upper layer of warm asphalt concrete coating using zeolite. The results of the material indicators that meet the regulatory requirements have been obtained.
