CELL STRUCTURE OF ROAD BED Russian patent published in 2009 - IPC E01C3/04 

FIELD: construction.

SUBSTANCE: in a highway, road bed design whereof provides for waysides, slopes, based in the road bed by longitudinal ditches filled up with bulk material, there are additionally introduced cross ditches, whereat longitudinal ditches are made along the road periphery and along the treadway lines, depth whereof is more than depth of freezing, and cross ditches with an increment increasing proportional to the transport load; ditches are filled up with discrete reinforcing material, for example, branches of trees, straw, etc and poured over by 90%…95% of the depth with binding composition, for example, clay-sand, with continuous fastened against each other in ditches cross hairs reinforcing elements placed thereon, for example polypropylene strips poured over with binding composition, provided that longitudinal reinforcing elements are strained ensuring compression stress in the surface layer.

EFFECT: reinforcement of the weak base, enhanced strength and bearing capacity of the road.
