Sažetak
Due to the poorly developed road network in Kazakhstan and the poor condition of the existing road communications, the issue of construction of new and reconstruction of existing roads is really crucial for the country. The article examines the problems of road construction in Central Kazakhstan, and proposes specific solutions to some of them. To reduce the construction cost of the subbase, the article suggests using a new building material instead of natural stone rubble. It is made of waste and by-products of manufacturing available in the region (blast-furnace slag and microsilica) hydrophobizated by used engine oil. Photos of the laboratory samples and the results of the experimental researches of this road-building material are attached to the article. To reduce the labour intensity of stiff and frozen soil excavation during the preparation of the subgrade, the article provides the use of a new working part of excavation machine. This working component is a cutterhead developed at the premises of The Karaganda State Technical University. The article deals with construction of this machine and principle of its operation.
