COMPOSITION OF SOIL-CONCRETE MIXTURE, SOIL-CONCRETE ROADBASE AND METHOD OF MAKING SAID ROADBASE Russian patent published in 2012 - IPC C04B28/04 E01C3/00 

FIELD: chemistry.

SUBSTANCE: invention relates to road construction and can be used in making roadbases. The soil-concrete mixture contains industrial-grade soil in form of grinding-sorting factory wastes and loose debris from Lebedinsky and Stoylensky Mining and Processing Combine and mineral binder in form of lime-containing wastes of sugar factories with activity of 28-35%, and cement, in the following ratio, wt %: industrial-grade soil 82-87; lime-containing wastes 5-7; cement 8-10. The invention also describes a method of making a roadbase and an soil-concrete roadbase.

EFFECT: high water- and frost-resistance of the roadbase material while improving and maintaining strength properties of soil-concrete.
