At the red clay slope along highway in south China,there exist poor scour resistance,severe water and soil erosion,plant seeds easy-to-lost and other problems.Hence orthogonal test was carried out to analyze the methods for soil improvement based on W-OH and based on artificial loam,and to get the optimal proportioning of base materials.Two design schemes of improvement were proposed,and applied to the section TJ5 of Huizhou—Qingyuan Highway.The result shows that the two techniques for soil improvement may increase the soil nutrient at the red clay slope,and the mechanical property and erosion resistance of the root-soil composite.
