Sammendrag
The main target of this project is to make a literature review on design guidelines/experience of EPS fill light - weight embankment. Design experience from four countries: USA, Norway, France and Greece are presented. Even if there are only quite a few documentation of failure in EPS fill embankments, having a common geotechnical consensus on parameter selection and design is necessary. Even if researches are carried out, there is still a tradition of using different EPS engineering material parameters from place to place. It has been a focus point for many researchers to document design procedures for EPS design and constructions for different uses. USA has many years of experience in using EPS as an alternative light weight material. Because of the increase in uses of EPS in road construction, transportation research board has produced a preliminary design manual for design of such fills. Along with other case studies, their experience in the design is included as one chapter. Design charts for seismic analysis and material parameters of EPS along with controlling measures are documented. Having a long experience and being the first user of EPS, Norway has an accomplished experience in using the material. Special construction procedures from Håndbook274, Håndbook016 and Håndbook 018 with information from case studies has been included. From experiences gained through more than 200 projects in EPS, France has produced a document on how to utilize EPS. Design procedure mentioned in the guide produced by the French committee for road engineering, CFTR, is mentioned. Greece’sdesign experience gained from utilization of EPS on one of their major highway has been included. Summarised EPS material parameters, performance parameters and European standard on EPS are presented in the last chapter.
