STABILITY OF THE SUBGRADE AND EVENNESS OF SURFACINGS (IN RUSSIAN)

THE INFLUENCE OF THE STABILITY OF THE SUBGRADE ON THE EVENNESS OF THE SURFACING IS DISCUSSED. SUBGRADE STABILITY DEPENDS ESSENTIALLY ON THE COMPACTION OF THE SOIL OF WHICH IT CONSISTS OR OF THE EMBANKMENT FOUNDATION SOILS. UP TO THE PRESENT TIME, THE GENERAL OPINION WAS THAT LESS ATTENTION NEEDED TO BE GIVEN TO UNDISTURBED SOIL THAN TO EMBANKMENTS BUT RECENT RESEARCH SHOWS THAT THIS IS WRONG AND ALSO THAT SOIL BEHAVIOR VARIES ACCORDING TO ITS POSITION IN RELATION TO THE FROST PENETRATION ZONE. STRICTER REQUIREMENTS SHOULD BE PLACED ON THE SOIL SITUATED IN THAT ZONE. RECENT SPECIFICATIONS ARE GIVEN FOR THE DENSITY OF SUBGRADE SOILS. IT IS DESIRABLE TO COMPACT NATURAL SOIL IN CUTTINGS UP TO THE DENSITY STATED IN THE SPECIFICATION, ASSUMING THAT THE MOISTURE CONTENT IS SUITABLE. /LCPC/RRL/
