This study aimed to analyze bearing capacity characteristics of laterite soil with quicklime stabilization as road subgrade layer. The laterite soil obtained from three different locations with three different ferrous (FeO) content. Soil samples were conduct by mixing laterite soil with 3%, 5%, 7%, and 10% lime content on Proctor initial condition, then cured for 3, 14, and 28 days before tested for soil bearing capacity using CBR laboratory test. Result showed that the lime treated laterite soil increases the bearing capacity for all types of laterite soil significantly in line with incrasing of lime content on 28 days curing time (11,67% to 51,67%, 14% to 53,33%, and 14,17% to 71,67%, respectively for LH1, LH2 and LH3). The increasing of soil bearing capacity due to pozzolanic strength gain. Based on these results, the laterite soil has potentially to be used as road subgrade layer.
