Index properties & strength of murum/Gravel soil is less and does not fulfill the requirement for its uses as a road pavement material such as GSB. These property is likely improved by adding a suitable admixture of stone dust/river sand. Therefore a detailed experimental study is proposed by adding & mixing combination of quarry soil (i. e. murum/Gravel soil) with stone dust in assorted percentage, to find suitable proportion of local murum/Gravel soil that will suit parameter for granular Sub-base material for low traffic volume roads in rural area.
Aim of this study to find out solution for use of local gravel soil/murum in construction of road pavement layers by adding suitable percentage of stone dust/river sand. To improve its properties and to make it suitable material for road pavement material like Granular sub-base. Following objects are taken in to consideration while study.
Keywords : Index property, adding stone dust, soil index improvement, strength of murum/gravel, liquid limit, plastic limit, sieve analysis.
