FIELD: motor road building in regions with negative mean-year temperature. SUBSTANCE: method for erecting earth bed includes cleaning road path from forest, thick brushes, and moss cover, building lateral water removing ditches, natural thawing out and draining base grounds, ground dumping to the base and reinforcing the ground followed by compacting. Brushes are used to reinforce earth bed. The brushes are laid uniformly on ground surface along all bed length. Then it is impregnated with spent lubricating oil. Then levelling layer is created of sand- gravel mixture, preferentially, of 5 - 7 cm thickness followed by compacting. EFFECT: high reliability. |
