METHOD OF UNIFORMITY INCREASING BY DURABILITY OF SOIL CEMENT Russian patent published in 2009 - IPC E02D3/12 E01C3/04 

FIELD: mining.

SUBSTANCE: method is in blending of at least 92% ground and 8% of cement by mass and implemented in following succession: in preliminary blending at least 3/5 parts of strengthened ground with water in amount 40-50% from total amount of water and with cement in amount 20-50% from total amount of cement; aging of mixture on air during 20-60 min.; blending of this mixture with mixture of rest components. Strengthened ground mass at first is divided for two parts in ratio "golden section" 0.67 and 0.33; then each part is separately blended with 50% of accepted cement mass, and received two mixtures by means of blending are united into common mass; after that received mixture is blended with specified amount of water, after what finished mixture is aged on air during 20-60 minute before piling and compaction of it into basis of road pavement.

EFFECT: development and creation of method of uniformity increasing by durability of soil cement.
