Engineering Application of Basic Level Materials of Red Mud High Level Pavement
The influence role of red mud bulk percentage, composite moisture percentage, lime quantity and additive for pavement basic level strength has been discussed in this paper. The result shows that the percentage of bulk with diameter 10 mm from red mud has influenced the compression stress and the percentage should be controlled less than 10% The compression stress of test sample is the highest when the percentage of composite moisture is about 45% Old red mud:fly ash :lime 75:15:10, which is the best mix ratio in practical project application. Lime powder and pulping of the additive can improve the initial stress of basic level. A highway is 4 km, with pavement basic level of red mud through coring. And its stress has arrived at the first class of lime industry waste stable soil and the stress requirements of the expressway.
