Cement stabilized soil as pavement base and sub-base materials has been extensively applied in various countries. Nevertheless, cement stabilized soil in tropical countries undergoes cracking problems and premature pavement distress, due to cyclic wet and dry seasons. Natural rubber latex (NRL) can be used as an additive to improve the serviceability and durability of cement stabilized soil. The effect of influence factors including soil type (low and high fines content), NRL type (low to high dry rubber content), NRL replacement ratio and cement content on the compressive strength prior to wetting and drying test (UCS₀), cyclic wetting and drying compressive strength (UCS_(w-d)) and weight loss was examined in this study. The cement-NRL stabilized samples had higher UCS values than the cement stabilized samples, for all cement contents and NRL replacement ratios tested. The NRL films enhanced the cohesion (inter-particle forces) but retarded the hydration effects. The highest UCS value was found at an optimum NRL replacement ratio, which was 20%, 15%, and 10% for 3%, 5%, and 7% cement, respectively. The lowest weight loss and highest UCS_(w-d) were also found at the optimum NRL replacement ratio. The UCS_(w-d) of cement-NRL stabilized sample was found to be higher than that of cement stabilized samples at all w-d cycles, even for the same UCS₀. The equation of predicting UCS(w-d) at various w-d cycles was proposed for various influence factors based on the critical analysis of test results. The input of cement can be reduced by NRL replacement to attain the same target UCS₀ and UCS(w-d), hence the reduction in carbon footprint. For the same UCS₀ = 4.4 MPa, the carbon footprint of 4.4% cement stabilized soil was reduced to 30.7% as compared to the 3% cement and 20% NRL stabilized soil.

水泥稳定的土壤作为路面基层和次基层材料已在各国广泛应用。然而，由于周期性的潮湿和干燥季节，热带国家的水泥稳定的土壤会遇到开裂问题和过早的路面困扰。天然橡胶胶乳（NRL）可以用作添加剂，以改善水泥稳定土的使用性和耐久性。影响因素包括土壤类型（低和高细粉含量），NRL类型（低至高干胶含量），NRL替代比和水泥含量对润湿和干燥试验（UCS ₀），循环润湿之前的抗压强度的影响干燥抗压强度（UCS _（wd））和体重减轻进行了这项研究。对于所测试的所有水泥含量和NRL置换率，水泥-NRL稳定的样品的UCS值均高于水泥稳定的样品。NRL膜增强了内聚力（颗粒间作用力），但延迟了水合作用。在最佳NRL替代率下，发现最高的UCS值，对于3％，5％和7％的水泥，分别为20％，15％和10％。在最佳NRL替代比例下，重量损失最低，UCS最高_（wd）。在UCS _（WD）水泥NRL的稳定化的样品被发现在所有WD周期为比水泥稳定化的样品的高，即使是相同的UCS ₀。基于对试验结果的严格分析，提出了在各种水力循环下UCS（wd）的预测方程。可以通过替代NRL来减少水泥的投入，以达到相同的目标UCS ₀和UCS（wd），从而减少碳足迹。对于相同的UCS ₀  = 4.4 MPa，与3％水泥和20％NRL稳定土相比，4.4％水泥稳定土的碳足迹降低至30.7％。
