Experimental and theoretical studies of the reinforced base of the pavement

The paper presents the results of stamp testing double-layer base of crushed stone and sand, reinforced with planar geogrid with steel fibers in a plastic shell. There are determined regularities of deformation and gotten the deformation characteristics of reinforced construction. Experimentally determined deflections of the reinforced base are compared with the results obtained theoretically. The reinforced layer of crushed stone is considered as a multi-layer plate on the elastic foundation, for calculation of which there is used the Bubnov-Galerkin method. The theoretical and experimental results are satisfactory coincided. The effect of reinforcement on deflections is established.
