Flexural behaviour of concrete pavements reinforced with geogrid materials
In this study, the flexural behaviour of concrete slab pavements reinforced with the triaxial geogrid in terms of tensile and compressive strain developments was experimentally investigated. Six concrete specimens were cast and tested under static applied load at three different loading positions which are: corner, edge, and interior loading positions. Three from these specimens were unreinforced (references) and the other three were reinforced with the triaxial geogrid layer. Thirteen strain gauges were used and fixed on the slab pavement surface to measure the strains developed during the loading. The parameters measured as the part of this study were the vertically applied load and the strains at the surface of concrete specimens. The findings show that geogrid reinforcements can improve the flexural strength of concrete pavements due to applying vehicle loads.
