Performance of Subbase Layer with Geogrid Reinforcement and Zeolite-Waterglass Stabilization

Some laterite soil is an inferior material for engineering applications such as road and highway pavement, dam construction filling material. Laterite stabilization required to increase its strength field application purposes. The potential use of zeolite waterglass stabilizing agents their pozzolanic properties. This study aims analyze the bearing capacity stabilized by waterglass-activated reinforced with geogrid. sample was prepared a percentage 4, 8, 12, 16 20%, much 2, 4 6% curing times 0, 7, 14 28 days. Furthermore, physical model test carried out in container optimum composition obtained from compressive (UCS) California (CBR) test. subbase layer geogrid reinforcement placed on subgrade substandard CBR value. results showed that time 7 days found significantly increased. value also increased content additive compared untreated soil. performance additives (ZW-geogrid) provides more optimal carrying load sand-gravel mixtures Doi: 10.28991/CEJ-2022-08-02-05 Full Text: PDF
