The Role Of Granulometry In The Bearing Capacity Of Pavement Foundation Layer

Authors : Melbouci Bachir . Messaoudi Noureddine .

Abstract

This work aims the study of the unbound aggregates made of gravel, sand and fines, mixed in several predefined particle size configurations, which are compacted at the Proctor Optimum in order to undergo CBR punching whose purpose is to determinate the different bearing capacities depending on the granulometries. Indeed, the sensibility of the foundation layer is related to several granulometry indicators which are related to several grain size fractions. The objective is to find the granularity of the granular foundation materials with the highest CBR value, thus which corresponds with the best overall performance of the pavement.
