METHOD FOR PREPARATION OF ASH-MINERAL MIXTURE FOR BASES OF ROAD PAVEMENTS Russian patent published in 2016 - IPC E01C3/04 

FIELD: construction.

SUBSTANCE: invention relates to road construction and can be used to prepare ash-mineral mixtures, laid in base of road pavements. Method for preparation of ash-mineral mixture for bases of road pavements, involving mixing mineral binder, filler, fly ash and moistening mixture, where at first stage is obtained mineral binder by dosed supply, wt%: portland cement 50-70, water-reducing additive in amount of 0.5-2.0 % of weight of portland cement (over 100%) and flue ash - balance, with subsequent stirring and combined grinding of dosed components in an activator-disintegrator, at second stage is dosed and successively discharged on each other, wt%: macadam-sand filler in amount of 57-68, obtained at first stage mineral binder in amount of 10-15, flue ash - balance, and at third stage said components of ash-mineral mixture are mixed and water is added to optimal moisture.

EFFECT: high bending tensile strength of constructed bases and, consequently, longer life.
