Behaviour of unpaved roads can be improved by laying a layer of geotextile at the interface of soft subgrade and overlying granular fill. Existing method of design of reinforced unpaved road consider increase in bearing capacity but no quantitative value of footing deformation is given corresponding to these bearing capacity factors. This paper presents a series of model footing tests under monotonic loading. The results of the tests are used to highlight the improvement in load carrying capacity of the reinforced unpaved road with the increase in fo9ting deformation. A set of non-dimensional parameter, p0 /Cu, similar o bearing capacity factor have been proposed for estimation of load carrying capacity of unpaved roads with the increase in footing deformation.
