FIELD: construction.
SUBSTANCE: method for enhancing road subgrade includes planning of the road subgrade, stretching across its surface of geotextile and geogrid, filling of cells of geogrid with filler. Filler is previously placed on the surface of the subgrade in front of the road car, then it is supplied to the place of fixation of the stretched geogrid by means of intake working member and conveyor, plan and compact into two stages, at first along the entire surface of the geogrid, and then in the band of action of the most intense probable load in order to prevent the tread formation, moreover the filler is moistened before laying into the geogrid and compaction.
EFFECT: improved efficiency and quality of the protective layer formation, increased stability of the base.
