Abstract
There is a large amount of red clay along a highway under construction in Southwest China. The red clay has high plasticity and small CBR which don’t meet the specification. This paper studied on red clay improvement by adding sand at foot of mountain. Research results show that the dry density of the improved red clay increases with the increase of the sand when the moisture content is the same. The optimum moisture content of improved red clay decreases with the increase of the sand. The maximum dry density increases with the increase of the sand. Liquid limit and plasticity index decrease after adding the sand. The CBR increases after adding the sand. The sand mixing ratio 4:6 was recommended to use in actual construction. And properties of improved red clay filler with the recommended ratio in actual construction meet the specification. Project implementation effect is very good.
