In the formation of this structure is a qualitative change in the natural properties of the soil. The introduction of cement into the clay soil leads to a significant reduction in the amount of macropores by filling the space between the soil units with hydration products, which in turn leads to a decrease in the permeability of the material. Soils with a high content of clay minerals are difficult to strengthen due to the tendency to clumping. This is confirmed by experiments in which it was found that the strength of the clay sandy loam reinforced cement above the loam and clay with the introduction of the same amount. Inactive or low-active zone in loam and clay corresponds to low costs of binder, which may be due to the uneven distribution of cement in clay soils, as well as low strength of soil aggregates, the surface of which does not interact with the products of hydration.<\/p>\n<p style=\"text-align: justify;\">The use of only Portland cement in the strengthening of heavy clays (the number of plasticity is not more than 27) is not enough to achieve high physical and technical properties, and, consequently, the production of high-quality road construction materials is possible only with the introduction of various modifying additives. When selecting the composition, several variants of cohesive soils and the percentage of inorganic binders (cement, Portland cement) were considered.<\/p>\n<p style=\"text-align: justify;\"><strong>Keywords:<\/strong> cohesive soils; strength characteristics; Portland cement organo-mineral mixture; bitumen emulsion; physical and mechanical properties; road clothing; testing; maintenance; device; repair; road clothing; coating; cement; Portland cement<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Katasonov Maksim Viktorovich Volgograd state university of architecture and civil engineering, Volgograd, Russia E-mail: max.inga@rambler.ru Kochetkov Andrey Viktorovich Perm national research polytechnical university, Perm, Russia E-mail: soni.81@mail.ru Gofman Dmitriy Ivanovich Volgograd state technical university, Volgograd, Russia E-mail: dima.0103@mail.ru Kuxhausen Vladimir &hellip;<\/p>\n","protected":false},"author":4,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[33,5],"tags":[],"class_list":["post-988","post","type-post","status-publish","format-standard","hentry","category-issue-2-2019","category-article"],"_links":{"self":[{"href":"https:\/\/t-s.today\/en\/wp-json\/wp\/v2\/posts\/988","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/t-s.today\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/t-s.today\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/t-s.today\/en\/wp-json\/wp\/v2\/users\/4"}],"replies":[{"embeddable":true,"href":"https:\/\/t-s.today\/en\/wp-json\/wp\/v2\/comments?post=988"}],"version-history":[{"count":2,"href":"https:\/\/t-s.today\/en\/wp-json\/wp\/v2\/posts\/988\/revisions"}],"predecessor-version":[{"id":1039,"href":"https:\/\/t-s.today\/en\/wp-json\/wp\/v2\/posts\/988\/revisions\/1039"}],"wp:attachment":[{"href":"https:\/\/t-s.today\/en\/wp-json\/wp\/v2\/media?parent=988"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/t-s.today\/en\/wp-json\/wp\/v2\/categories?post=988"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/t-s.today\/en\/wp-json\/wp\/v2\/tags?post=988"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
