This study presents results of an experimental program with respect to fiber's capacity of mitigating the swelling behavior of an expansive soil. Two types of tape–shaped fibers, i.e. fiber A (width fw = 2.5 mm) and fiber B (fw = 7 mm), were used as the reinforcements. The fibers were included at three contents, i.e. fc = 0.5%, 1% and 1.5%, each having two lengths or aspect ratios (fAR = 15/2.5 and 30/2.5 for fiber A, and fAR = 15/7 and 30/7 for fiber B). For a given fiber type (constant fw), improvement in swelling potential/pressure was observed to be a direct function of fc and fl (fiber length) or fAR, with the former taking on a more pronounced role. In addition, for a given fc and fl, ..View full abstract
