Abstract

Soil plays a vital role in supporting infrastructure. Clay soils deform under loads due to their high plasticity. Consolidation of the settling that occurs in clay soil takes an extended period because of their low permeability. The Palembapang area in Umbul Lioh, South Lampung faces the issue of low bearing capacity and road settlement. The study conducted soil improvement by mixing well-graded sand. The objective is to assess compression index (Cc), compression coefficient (av), coefficient of volume change (mv), consolidation coefficient (cv), and consolidation settlement (Sc) parameters for soil stabilized with well-graded materials. Different additions of 4%, 8%, 10%, 12%, and 16% were tested. The clay in our test is classified as A-7-5 (AASHTO) and OH (USCS). The addition of sand resulted in a decrease in the optimum moisture content value but an increase in the dry volume weight value during the compaction test. In the consolidation test, the addition of sand led to a decrease in the values of compression index (Cc), compression coefficient (av), coefficient of volume change (mv), and consolidation settlement (Sc), but an increase in the value of consolidation coefficient (cv).
