Effect of freeze–thaw cycles on unconfined compressive strength of fine-grained soil treated with jute fiber, steel fiber and lime (2014, background): “As for the steel fibers, they can improve the soil strength, but this improvement requiresmore investigation by comparing with the other fibers (Ghazavi and Roustaie, 2010; Gray and Al-Refeai, 1986; Murray and Farrar, 1988).”
Volume changes and mechanical degradation of a compacted expansive soil under freeze-thaw cycles (2019, background): “The cycles were continued up to 12 cycles, which was chosen since most soil strength reduction would occur in the primary cycles and after 5–10 cycles a new equilibrium condition would become predominant on specimens (Ghazavi and Roustaie, 2010).”
A simple review of soil reinforcement by using natural and synthetic fibers (2012, background): “Ghazavi and Roustaie showed that the addition of 3% polypropylene fibers (12 mm) results in the increase of UCS of the soil before and after applying freeze–thaw cycles by 60–160% and decrease of frost heave by 70% [106].”
