COMPACTION ROLLER DRUM Russian patent published in 2010 - IPC E01C19/28 

FIELD: building.

SUBSTANCE: in a drum comprising a shell ring, guides with in-built tamp load and restraints, the guides are made as separate inclined pipes of n-angular section, where n≥5. The deflection angles of the guides α≥ρ, where ρ is an internal friction angle of the reinforced material. The restraints comprise cavities mutually opposed at the ends of the guides.

EFFECT: improved reinforcement quality of road-building materials by lowering strain resistance, preventing surface fractures and adverse effect on a pavement of transverse shear stresses generated by motor carrier wheels at crossroads and turns ensured by development stress resistance structure of road-building materials.
