Waste materials are serious environmental problem because they have harmed to soil and ground water. Rapidly developing technology has increased production and consumption. The increasing of production and consumption results in the increase of amount of waste. In the developing countries, distinct rules of waste disposing are initiated to prevent the environment pollution. This case was positive effects on environment by means of recycling, regains to economy and reducing environmental pollutions. Recently, some waste materials were began to be used with clay in landfill layer design. Because the waste materials increases characteristic of clay liner such as impermeability, strength, heavy metal absorption, etc. In this study, waste marble dust was used as an additive material in landfill liner. Mixtures of kaolinite-bentonite were mixed with waste marble dust for design of landfill liner. This process was performed at marble dust ratio of 5%, 10% and 15%. Freezing-thawing tests were carried out in these mixtures. At the end of the tests, it was observed that waste marble dust increased strength of liner in conditions of freezing and thawing.
