Abstract

Papua New Guinea clayey soils are stabilized with various percentages of volcanic ash (VA), finely ground natural lime (L), cement and their combinations. The influence of stabilizers and their combinations is evaluated through Atterberg limits, standard Proctor compaction, unconfined compressive strength, splitting tensile strength, modulus of elasticity and California bearing ratio (CBR) tests. The durability of 38 stabilized soil mixtures is also conducted by studying the influence of water immersion on strength, water sorptivity and drying shrinkage. Correlations between compressive strength, modulus of elasticity and CBR are also established. Theoretical analysis of pavements incorporating subgrades improved by stabilized soils under traffic loads shows technical benefits compared with conventional flexible pavements without improved subgrades. Suitable stabilized soil mixtures using VA, L, cement and their combinations are proposed which can be used for the construction of road pavements, airfields, earth dams and low-cost housing. The use of locally available soils, VA and lime in the production of stabilized soils for such applications can provide sustainability for the local construction industry.
