Flexural Tensile Strength Testing of Stabilized Soil Samples

Traffic loading on a road surface causes compression in the upper layers of the structure and tension in the lower parts. These lower layers often consist of stabilized soils, for which the tensile characteristics are usually ignored. Tensile stress on the bottom of a stabilized layer should be used as a design criterion, as it is an important design parameter. For stretching tests rectangular soil cement beams were of 40x40x160 [mm] (BxHxL) size was prepared. The samples were developed in the Geotechnics laboratory of the Technical University of Cluj - Napoca. This is a first and important step of the research, as these parameters are not treated in any regulations or standards from Romania.
