Analysis of Settlement of the Road with Full Scale Geotextile Reinforcement on the Very Soft Soil (Case Study in Tapin Regency, South Kalimantan)

Abstract

in case of the construction of road in soft soil, it is necessary to consider the use of materials around the road construction site, and not to use selected material which is imported from outside the road construction site. Thus, aim to overcome the difficulties of using selected materials, namely the difficulty to obtain the materials, the price of expensive materials , the freight of material that could takes a long time period, high cost, and the use of materials that tend to be environmentally unfriendly. It is very necessary to learn about the use of nonstandard additive materials, taken to the road construction site, but with the use of geotextile reinforcement. The research method used is a full scale method in the form of trial embankment, so that the performance of the road can be observed for a long period of time due to the traffic and soil settlement. The results obtained is settlement that occur on the road from the combination of ordinary embankment material and local material, most frequently occured in a larger percentage of ordinary embankment than the local material. While the visual value is relevant to the settlement in which a larger percentage of ordinary embankment results in a better visual value, due to the quality of the ordinary embankment material is better than the local material.
