1080 IMPROVED DURABILITY Khan & Shrive (2026b) evaluated the influence of Duraflex admixture on the durability performance of cement-stabilized soils under severe environmental conditions, specifically freeze-thaw (FT) (Figure 83) and wetting-drying (W-D) (Figure 84) cycles. The results demonstrate that incorporation of DFI significantly enhances resistance to strength degradation and mass loss under repeated environmental cycling compared with cement-only stabilization. Duraflex-treated samples exhibit substantially lower weight loss across freeze-thaw cycles, indicating improved resistance to frost-induced structural damage as may be seen in Figure 4. Figure 83- Weight loss due to Freeze-Thaw cycles (Khan & Shrive, 2026b) Improved performance under F-T exposure indicates greater structural stability in snow-prone regions, while enhanced resistance to W-D cycling supports its suitability for high-rainfall environments. The combined durability improvements suggest that cement-DFI blends produce a more resilient and moisture-resistant stabilized matrix, contributing to extended service life and reduced maintenance demands in pavement subgrades, haul roads, well pads, and related infrastructure applications. The lower cumulative weight loss of Duraflex-treated specimens during wetting-drying cycles is presented in Figure 5, demonstrating improved resistance to moisture-induced degradation.
