Stabilization of dune sand using crushed sand, silt and blast furnace slag for use in road field
Highlights Crushed sand and silt with lime-activated slag are used to stabilize dune sand. Various mixtures were studied. Grain size distributions and compaction were examined. Shear strength, CBR, compressive and compressibility tests were performed. CBR, cohesion and compressive strength are enhanced 78%, 55 and 2226 kPa in 60 days.
Abstract Soil stabilization is a well-known technique to improve the mechanical properties of soils in road and railway construction by adding a grading corrector and/or hydraulic binders in the soil. In this work, dune treated sand is proposed to be used in pavement layers. For this, a series of tests, including sieve analysis, Proctor compaction, CBR, simple compressive strength, shear strength and compressibility tests are performed to evaluate the effectiveness of the adopted stabilization technique using dune sand, and to determine the optimal mixture for practical purpose. Our results show that for certain mixtures the lift (the CBR index) increases from ∼8% to ∼78% with the increase in resistance.
