“…It shows significant improvements were obtained compared to lime-stabilized expansive soil. Thus, the study concluded that using a mixture of brick powder and lime as stabilizers in subbase material in flexible pavements improves CBR and swelling [17].…”

“…Many researchers have found that the mixture of brick powder with other additives shows a significant improvement in the strength parameters of weak soils. They concluded that brick waste mixed with lime, cement, coir fiber, and fly ash can be used as subgrade and subbase pavement materials [13,14,15,16,17,18].…”

“…e change in the ductility of soil is usually assessed in two ways, either from the variation in the postpeak stress loss or from the variation in the axial strain at failure [49,50]. Alternatively, the ductility of the cement-stabilized clay reinforced with glass fibers can be expressed by measuring the variation of the energy absorption along the stress-strain curve and expressing it in terms of normalized energy absorption [51].…”

A series of triaxial compression tests were conducted to investigate the influence of the fiber content and confining pressure on the shearing characteristics of cement-stabilized clay reinforced with glass fibers. The glass fiber contents were 0, 1‰, 2‰, 3‰, and 4‰ by weight of the dry soil. The stress strain and volume change behavior, shear strength, and energy absorption of the test specimen were obtained. The results indicate that the inclusion of glass fibers can increase the shear strength, inhibit the volumetric dilation of the test specimen, and improve its brittle behavior. The cohesion of the cement-stabilized clay reinforced with 4‰ glass fiber content is 2.8 times greater than that of the cement-stabilized clay. The effect of the fiber content on the friction angle is not obvious. It is found that the glass fiber reinforcement is more substantial under a low confining pressure. The scanning electron microscopy test results show that the surface of the glass fiber is wrapped with cement hydrate crystals, which increases the bite force and friction between the fiber and the soil particles. A single fiber is similar to an anchor in the soil, which enhances the mechanical properties of the cement-stabilized clay reinforced with fibers.

“…Rudramurthy et al [ 20 ] studied the effects of different fiber contents on the mechanical characteristics of lime-treated clay by a series of unconfined compressive strength tests, and found that the ductility and brittle failure of soil samples were improved by adding 1% fibers. Dhar et al [ 21 ] proposed that the mechanical characteristics of lime-treated clay were improved after adding fiber. Turan et al [ 22 ] used unconfined compression tests to investigate the improvement effect of fly ash on the lime-treated clay, and their results indicated that the compressive strength, brittleness index, and secant modulus of soil samples were enhanced.…”

To improve the limitations of lime-treated subgrade soil (LS), a series of unconsolidated and undrained triaxial tests were conducted to investigate the improvement effect of fiber modified lime-treated soil (PLS) and fly ash modified lime-treated soil (FLS). The test results showed that (1) The deviatoric stress-strain curves of LS, PLS, and FLS were basically of the softening type. (2) The addition of fiber and fly ash improved the ductility and stiffness of LS. The ductility of PLS increased by 134% compared with LS, while the mechanical strength of FLS increased by 53%. (3) The microscopic tests showed that a denser skeleton structure was generated inside LS with the addition of fiber and fly ash. (4) The deviatoric stress-strain curves of LS, PLS, and FLS under different confining pressures were better characterized with the CES curve model. The above results indicate that fiber and fly ash can effectively improve the mechanical characteristics of lime-treated subgrade soil.
