Abstract

Cellular polymers represent an important category among the polymeric materials. Nowadays they experience large applications in different areas (packaging, building, sport, road safety). There is already a widespread geotechnical use of these materials, e.g. for settlements reduction or soil strengthening, especially for existing structures. However, a need of a deeper mechanical properties study is required. Oedometric and triaxial laboratory tests have already been carried out on polyurethane samples obtained from ready-to-be-used slabs (RTBU samples). However, because of a will of polyurethane foam injection inside the soil, an ad-hocprepared foam needs to be prepared and its mechanical properties to be investigated. This paper is therefore aimed to analyse the geotechnical behaviour of the ad-hoc-prepared foam (by testing AHP samples), studying the influence of several factors on the applicability, and comparing the results with the failure tests conducted on RTBU samples.
