METHOD OF MAKING PAVEMENT STRUCTURAL LAYER BASED ON ASHES OF EFFLUENTS SEDIMENTS COMBUSTION Russian patent published in 2013 - IPC E01C3/04 C04B28/00 C04B26/26

Abstract RU 2471913 C2

FIELD: process engineering.

SUBSTANCE: method of making pavement structural layer consists in mixing 30-70 wt % of ash of effluents sediments combustion with natural sand with particle size of 0-5 mm (the rest), 6-10 wt % of mineral binder, M400-grade cement or fine burnt lime with activity of, at least, 60 wt % of CaO and MgO. Mineral mix is damped with water. Said mix is mixed with 4-8 wt % of liquid bitumen "СГ" 90/130 cutback in 1:1 ratio and compacted at 30 MPa.

EFFECT: higher strength.
