Expanded Polystyrene for Road Embankment on Soft Clay

Written by Gouw Tjie Liong, Ir., M.Eng, ChFC, PhD. Posted in GTL Paper, Publication

ABSTRACT: Instability and  intolerable deformation always be the problems in constructing high embankment over soft/ loose soils. The prime cause of the problems is the load exerted by the self-weight of the embankment fill itself. Therefore, whenever possible, the use of lightweight materials, such as Expanded Polystyrene (EPS) foam, for the embankment fill will certainly be one of the best solution. This technique has been implemented in the Scandinavian countries. Seeing that it may also be implemented in our country, Indonesia, this paper tries to introduce the engineering characteristics of the EPS foam, as obtained from manufacturer, together with its design aspects.

Dr. Gouw is a certified Professional Geotechnical Engineer. He has been working in the field of Geotechnical Engineering since 1984. His expertise covering geotechnical investigation, soil instrumentation, deep foundation and excavation for high rise buildings, pile load testing (Static and PDA), pile integrity testing (PIT), sonic logging test, vibration monitoring, slope stability, ground anchors, pumping test, dewatering, micropiles, tunnelling and ground improvement works, e.g. dynamic compaction, vertical drain, vibro-compaction, geosynthetic and grouting. The jobs cover more than 180 projects in Indonesia, Singapore and Srilanka. He has a great passion in the teaching and disseminating of geotechnical engineering knowledge. He serves as lecturer since late 1984. Currently, he serves as Associate Professor at Podomoro University, Jakarta for undergraduate study, and for post graduate students at Universitas Katolik Parahyangan, Bandung, Indonesia. He also conduct regular geotechnical training for engineers. He also chaired the Indonesian Chapter of International Geosynthetics Society since 2006. He has published 80 papers and 22 technical notes.
