In the swampy area due to the characteristics of the material, combining solidity and lightness, phosphogypsum is not interchangeable at all. It allows you to make reliable and durable roads. The design is obtained up to five times stronger than the required standards. At the same time, at the first stage of construction of the road, it is possible to make an intermediate type, making the bases of phosphogypsum, and later laying the remaining structural layers of crushed stone and asphalt. In this case, the coating of technical gypsum is not destroyed, even with the passage of heavy tracked vehicles and at low temperatures.<\/p>\n<p style=\"text-align: justify;\"><strong>Keywords:<\/strong> phosphogypsum; dihydrate; hemihydrate; road; structural layer; a base; a by-product; the construction of the landfill<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Kochetkov Andrey Viktorovich Perm national research polytechnical university, Perm, Russia E-mail: soni.81@mail.ru Shchegoleva Natal&#8217;ya Vyacheslavovna Saratov state technical university of Gagarin Yu.A., Saratov, Russia E-mail: Shegoleva123@mail.ru Korotkovskiy Sergey Alekseevich Saratov national research state university name&#8217;s N.G.
