Road settlement analysis on improved peat soil in Pekanbaru

Abstract

Indonesia is one of the countries that has the largest area of peat soil. Construction on peat soil may cause problems to the structure due to poor physical properties of peat soil such as having low bearing capacity. There have been several cases where roads built on peat experience damages, like uneven road due to settlement. This research presents a study in peat soil with soil improvement where the peatland was used as a location for road construction, which the bearing capacity, settlement and time required for settlement to take place is predicted. The analysis was conducted in a condition where the pavement is placed from the elevation of 0,0 m to -0,88 m, and the pavement is considered as a reinforcement layer. This research presents the bearing capacity, amount of settlement occurred, and the time needed for consolidation of roads on improved peat soil.
