... and crushing of the EPS Geofoam blocks are adopted as performance criteria. Obtained results indicate that in general, the use of both low- and high-density geofoam blocks significantly improved the seismic performance of pipelines. The critical fault displacement value (d_cr) leading...

... crown’ and ‘the pipe covered with compressible inclusion’) were tested and expanded polystyrene (EPS) Geofoam with 10 and 15 kg/m³ nominal density was used as compressible inclusion. To simulate geostatic stresses imposed by high embankment fill, the surcharge stress up to 200 kPa was applied...

...T. Hakimi Basti; R. Jamshidi Chenari; A. Firoozfar A two-part study was undertaken to evaluate the dynamic behavior of sand-EPS geofoam composite layers. The first part aimed at evaluating the dynamic properties of both sand and expanded polystyrene (EPS) geofoam, by performing a series of bender...

... tests on EPS samples were also performed according to ASTM D1622-08 , and a detailed discussion of their results for densities of 20, 30 and 40 kg/m³ is provided in Section 6.1. A summary of the engineering properties of EPS is shown in Table 2 . This EPS geofoam is comparable to those used...
