FIELD: construction.

SUBSTANCE: invention relates to construction and can be used for construction of an earth bed and a facility 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. Road-building material containing drilling sludge with density of 1.3 to 1.8 kg/dm³ and with humidity of 30%, cement as the main binding material in the amount of 5-15% of the weight of the mixture, wastes of thermal utilisation of oil sludges (ash slag) with density of 1.2 to 1.6 kg/dm³ in the amount of 30-40% of the mixture weight, mineral filler and a sorbent - complexing agent, where organic fibrous (peat) sorbent is used as the sorbent - complexing agent in the amount of 2-4% of the mixture weight; Portland cement is used as cement; additionally, it contains liquid glass or organohydride-siloxanes, and sand is used as filler, with that, content of sand as a part of material is 5, or 10, or 30 wt %. The invention is developed in subclaims of formula of invention.

EFFECT: reduction of cement consumption; improvement of environmental situation due to utilisation of wastes of drilling and an ash and slag mixture.
