Macadam and sand mix
Making of the road bed using interspersing method with high-strength hardly compacted macadam according to the existing material consumption rates results in poor quality of the roads and is a very labour-intensive process. That is why an experimental ground with macadam bedding made of 20 cm thick C-4 macadam and sand mix was built on the drive to settlement Zangar Kul’ in Rybno-Slobodsky district of the republic by JSC “Tatatvtodor” in 2012. The technology of macadam and sand bedding consists of less operations than the interspersing technology, and the mix is spread in one layer, it does not need interspersion with additional matters and can be more easily compacted, so that the road building takes much less time. In 2013 the company is planning to use C-4 macadam and sand mix on several sites in Aksubayevsky, Apastovsky, Mamadyshsky, Prigorodniy and Sabinsky branches.
