MOTOR ROAD ON PERMAFROST SOILS Russian patent published in 2015 - IPC E01C3/00 

FIELD: construction.

SUBSTANCE: proposed motor road on inhomogeneous soils over bed width includes earthwork with geosynthetic material. Earthwork slope part on the side of weak bed, a thrust soil roll is made of mineral frost-free soil. The latter is banded by reinforcing geosynthetic material arranged in under-slope part of motor rod bed and earthwork slope part. It makes a semi-shell with bottom edges fitted in the depth of soils with the help of anchor bar fitted in the hinge. The latter is composed by lower edges of reinforcing geosynthetic material.

EFFECT: higher stability, decreased vertical and horizontal deformations.
