Mesl - a new appraisal

The mesl (membrane encapsulated soil layer) was originally designed to achieve a better distribution of stresses in a road pavement over a weak subgrade. This principle has now been theoretically and practically reappraised. The design parameters developed do not require the use of a wholly impervious membrane, but are equally applicable to a semi impervious membrane. The necessary parameters for road pavements in arid and semi arid regions subject to sporadic flooding, as well as regions with seasonally high water table conditions are presented, with particular reference to the requisite strength characteristics of membrane and encapsulated soil. This theoretical appraisal has been followed by field trails, on roads carrying an appreciable volume of heavy traffic, (up to 2000 vehicles per day) for some 1 1/2 years to the present time. Deformation and deflection (permanent and elastic displacements) at the pavement surface are being followed in comparison with control sections comprising both normal and lime stabilized work.
