WEIGHTLESS ROLL FOR COMPACTION OF SOILS AND OTHER POWDERY MATERIALS WITH DENSITY THAT CORRESPONDS TO THEIR DENSITY LIMIT

摘要

FIELD: construction, road engineering.;SUBSTANCE: invention relates to compacting equipment, in particular to rollers for compaction of soils and other powdery materials. Roller for compaction of soils and other powdery materials with density that corresponds to their density limit includes frame and roll. Frame is arranged with the possibility of displacement along compacted layer by means of displacement mechanism arranged beyond the limits of rolled layer for longitudinal displacement of roller roll along compacted layer. Roll is mounted on frame with the possibility of its suspension over compacted layer so that its lower generatrix just touches upper design surface of compacted layer.;EFFECT: invention provides for even density along whole thickness of compacted layer with direct control of compaction quality in process of rolling.;1 cl, 5 dwg
