Abstract Transport construction, including road construction, consumes a huge amount of materials, including new materials of a wide range: stone materials, sand and sand-gravel mixtures, mineral and organic binders, metal, etc. In the direct costs (cost of materials, operation of machines, wages of road workers), the share of the cost of materials reaches 60%. Often, the region in which the road is being built does not have its own standard materials, and these materials have to be delivered from other regions. For example, many regions of the Central region of Russia are forced to import crushed stone of hard rock from Karelia and the Leningrad region, and bitumen - from the Volga region. For the Moscow region, the shortage of building sand is more acutely felt in recent years, and this is only one side of the problem of material support of construction.
