Description

Rapid population growth, increasing user demand of land for living, transportation, industry
Initialization, educational institution and various types of power stations built on the sub-soil.
For the construction of new infrastructures it is important to have a high strength (quality) of
Soil and along with the possible effect of cost-effective and also fully save the environment.
Nowadays, it is the major challenge for civil engineer to improve sub grade soil for
construction work. Recent illustration about construction of highway or roadway is weak sub
grade soil. Soil reinforcement is the method associated with the increase of strength and
decreases the deformation properties of soil. This paper discussed regarding the effects of
fiber on the CBR value of a clay soil reinforced with Nylon fibers. A series of CBR tests were
conducted on samples of unreinforced and reinforced clay with different percentages of
randomly distributed nylon fibers. The soil samples were prepared by its Maximum Dry
Density (MDD) and Optimum Moisture Content (OMC) as well as in this study, different
percentage of fibers by dry weight of soil is used. The CBR values have been founded from
present investigation are 3.55, 4.57, 7.70, and 7.83 by using 0.0%, 0.25%, 0.5% and 0.75%
of Nylon fibers respectively for 30 mm length. Correspondingly, the CBR values have been
founded from present investigation are 3.55, 5.31, 8.20 and 9.22 by using 0.0%, 0.25%, 0.5%
and 0.75% of Nylon fibers respectively for 60 mm length. Also, the diameter of the nylon fiber
was constant at 1 mm. This investigation exemplify that the CBR value increased significantly
with the percentages and length of the nylon fibers. For the greater value of CBR thickness of
the pavement will reduce.
