Аннотация
The main type of road surfaces in Kazakhstan, as well as abroad, are asphalt concrete pavements. Most of the financing in the road sector (up to 80 %) is spent on repairs. This is due to the low inter-repair service life of the coatings due to increased traffic intensity and underfunding of repair activities in full.
The problem of ensuring the durability of asphalt concrete pavements is one of the most urgent. Its solution requires significant expenditure of material and labor resources. Due to the high cost of road construction materials, the issues of using new technologies, efficient and non-traditional materials, waste and by-products of industry in road construction are of particular importance. First of all, this applies to such technologies and materials that could improve the quality of asphalt concrete coatings, reduce the consumption of expensive binders of petroleum origin. The technologies under consideration also provide opportunities for the use of high-tonnage waste and industrial by-products as part of asphalt concrete mixtures. The issues of using high-tonnage waste and by-products of industry are also important because they allow simultaneously solving the problem of the environmental plan - to free up huge territories of land occupied by waste, to prevent environmental pollution.
