Abstract

Indonesia is an archipelago country that there are about thirty percent lowlands covered by deposit soft soils or peat soil. Local government has been built road infrastructure, but the soft soil layer has problem for soil stiffness. Ministry of Public Works has published guideline for road construction on soft soil of peat soil, which reinforced timber pile. A number Indonesian researchers have been reported that mattress reinforced timber or bamboo, its can be reduced and distributed loads from the embankment. Those investigation results were performed by trial construction method and laboratory tests in small scale. Unfortunately, these guidelines and result studies were reccommended to work trial construction method for design, and also must be conducted monitored data to the software package to simulate the criteria of design for embankments. In application of this design method is still difficult to handle by Indonesian local. In order to propose an empirical calculation method based on rule of geotechnics, the application of traditional reinforcement system for foundation soil is placing a certain layer of wooden stems as mattress on the ground surface. In these proposal calculations were provided design criterion, which purposed to reinforce, and give up floating force and as well as distribution of loads from embankment. Therefore, in this study was employed the empirical calculations method by applying index soil properties on different site for design. Finally, these calculation results were presented on graphs of correlation between the bearing capacity of foundation soil and the loading pressure distribution. These graphs may guide Indonesian local to design and handle embankment construction on soft ground.
