Композиционные подрельсовые основания. Материалы

По эксплуатационным свойствам, экономичности, решению экологических проблем и устойчивому развитию железнодорожного транспорта композиционные подрельсовые основания являются отличной альтернативой традиционным конструкциям из древесины, стали или железобетона. В обзоре показано, что по основным эксплуатационным характеристикам композиционные подрельсовые основания, и в частности наиболее распространенный их вид – композиционные шпалы, превосходят свойства традиционных конструкций. На основании более 100 литературных источников сведения о свойствах применяемых материалов и сравнительные характеристики материалов традиционных и композиционных подрельсовых оснований представлены в виде 14 таблиц. Обобщены исходные материалы для их получения, выявлены системные требования к материалу композиционных подрельсовых оснований, рассмотрены перспективные направления их развития в отношении исходного сырья, что является важной информативной базой по подбору сырья для расширения производства композиционных конструкций для железнодорожного транспорта.
