Abstract

The change in shrinkage characteristics which is an abnormal behavior of clayey soils is the subject of investigation. The focus is on the impact of short random fiber inclusion on shrinkage characteristics of CH soil which is used as the clay liner material. To examine the possible improvements in the soil characteristics, soils were reinforced with 0.2, 0.4, 0.6 and 0.8 percent fibers as dry weight of soil with 10, 15, 20 and 25mm lengths. Results indicated that shrinkage limit showed an increase, whereas shrinkage index, shrinkage ratio and volumetric shrinkage decrease with increase in fiber content and length.
