FIELD: construction.
SUBSTANCE: invention relates to construction and can be used for construction of an earth bed and a device of reinforced road bases on roads of categories I-V in road climatic zones II-V, as well as pavements on roads of categories IV-V as material for construction of earth bed fills and reinforcement of soil bases of construction and other sites. Improved road-building soil is characterised by the fact that it is obtained from a mixture containing the following, wt %: cement 5-15, waste of thermal utilisation of oil slurries - ash and slag with density of 1.2 to 1.6 kg/dm3 30-40, mineral filler 0-30, peat sorbent 2-4, drilling slurry with density of 1.3 to 1.8 kg/dm3 is the rest.
EFFECT: reduction of consumption of cement and fillers; utilisation of wastes.
