METHOD OF PREPARING BLACK CRUSHED STONE Russian patent published in 2003 - IPC

Abstract RU 2204538 C2

FIELD: production of road-building materials. SUBSTANCE: method involves impregnating black crushed limestone with viscous bitumen melted at temperature of 110-120 C. Crushed limestone dried to permanent weight is preliminarily impregnated with liquid soda glass having module of 2.7 at temperature of 20-22 C under excessive pressure of 1.0-6.0 MPa for 60-180 s. Impregnation with melted bitumen used in an amount of 3.0% by weight of crushed stone is carried out by mixing until uniform coating of crushed stone is reached. Method is used for constructing trunk road bed and coating and allows fracturing of crushed stone after compaction to be reduced on the average by 1.10-1.67 times as compared to known control methods. EFFECT: increased efficiency and reduced loss of crushed stone. 1 tbl
