The purpose of this work is experimental definition of influence of reinforcing of crushed-stone layers of road carpet by volume geogrid on shift stability. Materials for the research are three fractional compositions of crushed stone: screenings of 0-5 mm; fr. 5-20 mm; fr. 20-40 mm. Reinforcing is made by GEO OR geogrid 20/5 with a size of cell of 16х16 cm and edge high of 5 cm. As a result of comparative tests of crushed-stone materials of different fractions for shift in the horizontal plane with the use of geogrid and without it, significant experimental data have been obtained.
