FIELD: construction, particularly road paving.
SUBSTANCE: method involves in-situ preparing crushed-stone based mix; laying the mix on ground or drain layer in one or several layers; moistening the mix; impregnating thereof with emulsified asphalt and compacting the base. The crushed-stone based mix includes blast-furnace slag in amount of 30% by weight and steel slag in amount of 70% by weight or only blast-furnace slag. Before base compaction bitumen-mineral emulsion including liquid phase, namely potassium carbonates or sodium carbonates in amount of 1-10 l/m2 is added in slag-and-crushed-stone mix. The emulsion is poured over the mix and mixed thereto along with following mechanoactivation of obtained composition with medium-heavy and heavy road-rollers. Base is compacted with ramming road-roller.
EFFECT: increased strength and uniformly-distributed road paving stability during operation thereof, possibility of base structurization with time.
