Opis

Expansive soils are highly problematic by virtue of their innate capacity to undergo volume changes corresponding to changes in moisture regime. They swell and shrink respectively when water is absorbed in rainy seasons and when water evaporates in summers. As a result, lightly loaded civil engineering infrastructure founded in these soils are severely damaged. Many innovative foundation practices have been suggested for mitigating the problems posed by expansive soils. Some of these techniques are physical and chemical alteration and special foundation techniques in the form of tension-resistant foundations. This monograph presents the efficacy of fiber-reinforcement of expansive soils in reducing swelling and shrinkage. The tests conducted to find out swell potential and swelling pressure and other important engineering properties of the expansive soil samples reinforced with fiber have yielded useful results.
