“…Similar to the findings reported in the literature [2,4,11,29,35], the test results suggest that the fiber reinforcements can change the brittle behaviour of the clay to a somewhat more ductile (i.e., strain hardening) one. Also, the test results present, in general, a decrease in peak stresses by increasing the number of freeze thaw cycles for both reinforced and unreinforced samples.…”

“…During the last few decades, randomly distributed fiber reinforcements have attracted increasing attention in geotechnical engineering [2][3][4][5][6][7][8]. The primary purpose of reinforcing soil mass is to improve its stability, increase its bearing capacity, and reduce settlement and lateral deformation [9][10][11]. In comparison with conventional geosynthetics, the advantages of using randomly distributed fibers are as follows: a-Randomly distributed fibers are simply mixed with soil, just like mixing soil with additive materials.…”

“…Past studies performed to assess the benefits of using synthetic fibers in conjunction with chemical stabilization are discussed in the following sections. Kumar et al (2006) studied the compressive strength of compressible clay upon plain and crimped polyester fiber inclusion. The dosages of fibers were maintained at 0.5, 1, 1.5 and 2%.…”

This paper evaluates the effectiveness of stabilizing expansive soil with two different types of fibers, Fiber Mesh® (FM) and Fiber Cast® (FC), in conjunction with chemical stabilization. The intention of this study is to evaluate the effect of these fibers and lime in stabilizing expansive soil by improving its UCS behavior. The effect of varying lengths (6 mm and 12 mm) and amounts (0.2, 0.4 and 0.6% dosage by weight of soil) of FC and FM fibers and curing periods (0, 7, 28, 60, 120, 180 and 360 days) on the UCS and on secant modulus of a semi-arid expansive soil, in the presence of lime, was investigated. The main focus of this paper is on the determination of optimum fiber reinforcement parameters (in terms of fiber type, length and dosage) for the stabilization of expansive soil in terms of UCS, which is of a prime importance in soil stabilization projects for practicing engineers. In deterministic optimization, the uncertainties associated with subgrade soil of the pavement system are not explicitly taken into account. Hence, resulting optimal solutions may lead to reduced reliability levels of the pavement. Therefore, this paper also focuses on determining the optimum amounts of reinforcement for desired UCS performance of lime blended expansive soil using target reliability approach (TRA). The experimental data was used to develop a parabolic model using factors such as, length and dosage of fiber types to predict UCS as a response variable. In addition, it was concluded that the TRA can be successfully employed in expansive soil stabilization applications in determining the optimum length and dosage of fiber reinforcements.

“…Various types of tests have been performed by researchers on fiber reinforced soils such as triaxial tests, unconfined compression tests, CBR tests, direct shear tests, and tensile and flexural strength tests [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22]. The incorporation of randomly distributed fibers offers the prime advantage of overcoming the weak potential planes which usually develop parallel to the oriented reinforcement [7].…”

This paper presents the experimental results obtained from tests conducted on clayey soil specimen stabilized with pond ash (PA) and cement and reinforced with randomly distributed fibers. The amount of PA and cement were varied from 0-50 and 0-6 % respectively by dry weight of the soil. In order to understand the influence of admixture on the strength properties of clay, compaction tests, unconfined compression tests (UCS), split tensile strength (STS) tests and California bearing ratio tests (CBR) were conducted. In addition scanning electron microscopy and X-ray diffraction tests were carried out on certain samples in order to study the surface morphological characteristics and hydraulic compounds, which were formed. The specimens were tested for their strength behaviour at different curing periods. The obtained results have shown that addition of mixtures leads to a decrease in the maximum dry density and increase in optimum moisture content. The results also indicate that the proposed method is very effective to improve the strength of the clayey soil in terms of UCS, STS and CBR tests.
