The effect of Lubricant Oilson the Swelling Behavior of Loam

Abstract

In the world, Soils with different properties are available andit is distinguished based on the particle size and the consistency limits. Expansive soils are special soil type that is very sensitive to any change in their inner water content. Such Soils show a noticeable volumetric deformation as response to any variation in their moisture content which in turn affects the over-lied construction badly. Loam soil is a good example of expansive soils that was collected from El-MahmoudeyaLake that is in Alexandria Governorate, North of Egypt. This investigation aims to study the effect of Lubricant oils on the swelling behavior of the loam soil. Lubricant oilswere chosen in this work to minimize its negative environmental impact by finding a new utilization area for itand due to its economic effect as it is considered the least cost treatment method and to detect its ability as stabilizer to use the soil as an adequate fill instead of importing a new one. The swelling parameters effectiveness were studied through the Atterberg limits, free swell, and swell pressure tests.
