MOTOR ROAD Russian patent published in 2017 - IPC E01C3/06 

FIELD: construction.

SUBSTANCE: motor road in areas with complex engineering-geological conditions includes a roadbed with accommodation of subgrade thrust roller made of mineral nonfrost-susceptible soil in the sloping portion along the road axis, bordered by reinforcing geosynthetic material placed under the slope of the road base and part of the earthwork slope forming a semi-holder using a mounting rod inserted in the loop formed by the lower edges of reinforcement geosynthetic material. Rods made of composite material with a hook fixedly retaining the lower edge of geosynthetic material engaging the mounting rod are installed in one or two rows along the roller length. Activities are executed on one or both sides, depending on the nature of deformations.

EFFECT: increased resistance of earthwork, exclusion of soil vertical uplift at the roadbed base, reduced vertical and horizontal deformations of coverage, curbs and foundation soils, reduced width of opening and length of longitudinal and transverse cracks, exclusion of subsidences and waves on the pavement surface.
