dc.description.abstract-translatedEPS Geofoam is an appropriate lightweight material for reducing dead load of road embankments and hence, mitigating settlements of pavements constructed over poor ground conditions. Although, it has been used successfully in many projects during the last 50 years, there are still drawbacks regarding its application and design, requiring deeper investigations. A serious problem is related to development of rut and crack on the pavement surface. This paper presents the results of repeated plate load tests, describing the influence of EPS density and EPS layers’ thickness as an important factors affecting the performance of these embankments. In practical applications, two layers of EPS with different densities are used and the density of the bottom layer should be minimized in order to reduce overall cost of the pavement along the road. It has been observed that incorporating layers of EPS geofoam with inadequate thickness and densities lower than 20 kg/m3, significantly reduces the ability of such pavements to tolerate against rutting. Lower EPS densities also show a less reliable response with a noticeable number of loading cycles.en
