Potential uses of petroleum-contaminated soil in highway construction

Effect of Cement on Treatment of a Clay Soil Contaminated with Glycerol

“…As mentioned above, in these cases the reduction in pH reduces the hardening of the sample and results in reduction of strength. These findings are in agreement with the results that were reported by Hassan et al (2005). They concluded from strength tests on a petroleum contaminated soil mixed with 5, 10 and 15% cement for different curing times (7,14 and 28 days) that the strength is increased for 5% cement.…”

“…The reduction in specific surface can cause reduction in optimum water content. These results are not in agreement with the results that were reported by Hassan et al (2005) who indicated that adding cement to petroleum-contaminated soil causes reduction in maximum dry unit weight and optimum water content. However, dry unit weight that is resulted from compaction is a function of soil minerals, texture of clay soil, interaction of particles with pore fluid and the applied compaction energy (Croft 1967).…”

“…Organic compounds affect the cement hydration by retarding reaction via formation of a protective film around the cement grain, hindering the production of calcium hydroxide and accelerating the reaction via modification of colloidal C-S-H (C=CaO, S= SiO 2 , H=H 2 O) gel precipitated at very early stages around cement grains (Edmeades and Hewlett 1988). Hassan et al (2005) studied the behaviour of a petroleum-contaminated soil and concluded that the contaminated soil can be stabilized with cement as an agent and used for road construction.…”

Effect of Cement on Mechanical Behavior of Soil Contaminated with Monoethylene Glycol (MEG)

“…They mixed 5% cement, 10% fly ash and 20% lime with a petroleum contaminated soil and found that the treated soil gained the highest strength. Hassan et al 16 performed an experimental study on the use of petroleum contaminated soil in construction of highways and concluded that petroleum contaminated soil mixed with crushed stones can be used as base and sub base material in highways.…”

Application of Used Engine Oil in Soil-Cement Stabilization

“…Similarly 60% PCS/sand replacement can be achieved in the production of concrete hollow blocks with compressive strength and density criteria being satisfied [8]. Furthermore, Hassan et al, [9] while considering the potential use of PCS in highway construction found that the Maximum Dry Density (MDD) and the Optimum Moisture Content (OMC) of the uncontaminated sample was higher than the contaminated sample mixed with cement in the range of 5-15%. He concluded that 10% PCS partial replacement can be used as a base course and higher partial replacement percentages for the sub base while up to 40% partial replacement can be achieved in hot mix asphalt for medium to light weight traffic.…”
