The geotechnical improvement of stabilized peat using lime

Chemical stabilization of soil using lime is one of the old methods which have been used to improve the soil performance. Many research papers on the usage of cement as the soil stabilization material has been done all around the world; but peat stabilizing with lime has been in the less research attention so far. Since, many of the upper layers of linear project`s substructure, like roadway and railroad as well as pipeline projects especially in forest lands and agriculture fields is from organic soils, then it would be worthwhile making the substructure`s soil stabilization appropriately. This study attempts to test the improvement of the physical and geotechnical properties of stabilized peat soils using some laboratory samples with different percentages of peat soil and hydrated lime. The results indicate that the use of lime in peat stabilizing obviously makes significant improvements on the geotechnical properties of these kind of soils.
