Abstrakt: Through the compaction and permeability tests on loess, either natural or compacted loess can meet the requirement of the Landfill Pollution Control Standards about impermeable clay. While the compaction weathered red soil layer of the tertiary, widely distributing under the loess, whose permeability coefficient is less than 1×10-7cm/s. In this study we mixed loess with weathered red soil to obtain a new kind of composite soil, and drew a conclusion that the composite soil can meet the requirements of Chinese national standards. When the clay content of composite soil reached 21%, the permeability coefficients are generally able to meet the requirement.
