Determination the properties of bitumen and resin impregnated geotextiles
The excessive settlement, insufficient bearing capacity or stability problems occur with respect to increase in external loads on structural foundations or slope conditions. To solve these challenges reinforced soil applications have become crucial for the construction sector in terms of providing economical and effective solutions. In this study, it is aimed to increase the mechanical characteristics of geotextiles such as bearing capacity during separation purpose, puncture resistance, and tensile strength. Thus, three different types of woven geotextiles were impregnated with bitumen and synthetic resin, and the change in strength values compared to the original specimens and their effects on the bearing capacity of the soil were evaluated within plate loading tests. The load-displacement graphs were drawn by performing plate loading tests. Based on the results of another test performed, the tensile test, the innovative geotextiles demonstrated superior tensile strength and enhanced ductility relative to the reference geotextiles. The highest bitumen (1821 gr/m2) and resin (4280 gr/m2) impregnation rate was observed in PP 5000 H type of geotextile. According to different geotextile and impregnation types, values between 43.11% decrease and 20.82% increase were obtained at 10 mm settlement level in plate loading tests. Although the bitumen coating provided a large amount of resistance in terms of puncture resistance, the sufficient bearing capacity levels could not be obtained due to the brittle behavior of resin. When the tensile strength test results were examined, it was determined that impregnated geotextiles had properties that can provide both bearing capacity and tensile strength mobilization within geotechnical projects.
