Abstract
AbstractThe effect of treating limestone quarry fines (LQFs) with a commercially available liquid polymeric soil stabilizer, and a combination of the polymeric soil stabilizer and a small quantity (4%) of portland cement was evaluated. The research reported in this paper, which consisted of tests on both treated and untreated mixes, with the aim of evaluating the use of LQF in pavement construction was comprised of the following tests: (1) compaction, (2) unconfined compressive strength, (3) static flexural strength, and (4) durability. Test results showed marked improvements in the optimum moisture content, unconfined compressive strength, and static flexural strength, and no improvement in maximum dry density when polymer or both polymer and cement were added. Improvements in unconfined compressive strength were above the U.S. national requirements for admixtures for soil stabilization. Polymer-treated specimens were more susceptible to moisture than specimens treated with portland cement (PC) alone, an...
