FIELD: road construction materials.
SUBSTANCE: invention relates to industry of road construction materials and can be used in road construction as a structural layer of the base of road pavement or an additional layer of road pavement. Modified cement ground for road construction contains mineral binder portland cement (PC), nanosized oxides of silicon (10-15 nm), aluminium (5-10 nm), jointly activated in a vortex layer apparatus (VLA), and water at the following ratio of components, wt.%: portland cement “ЦЕМ”I 32.5 H – 9.6-10, soil – 90-90.4, silicon nano-oxide (10-15 nm) – 0.5-1% of PC, aluminium nano-oxide (5-10 nm) 0.6-1.5% of PC and water – 10-20 to optimum moisture content.
EFFECT: as a result of application of modifiers frost resistance of cement soil and its durability is increased.
