Determination of Degradation and Compressive Strength of Polyurethane Resin Applied for Bridge Abutment

Abstract

This study is carried out in order to review the deformation properties, strength, applications and suitability of polyurethane resin as a ground improvement method applied for bridge abutment construction. Since it is applied in the ground, awareness on polyurethane degradation needs to be emphasised. Deformation properties were determined for resin injections before and after degradation. The degradation of samples was studied by exposure to gasoline, diesel, oil, NaCl salt solutions with different concentrations (59, 193 and 301 kg/m3) and a mixture of fungi. After the degradation tests, compressibility tests were also performed. The use of resin as a ground improvement method has several advantages over conventional methods. The information presented enables road and bridges engineers and construction professionals to make competent decisions about implementing this innovative technique in the projects.
