In the search for alternatives to bioremediation of soils, this research aimed to analyze the effects of lime, cement, and asphalt as stabilizers on clayey gravel and sand soil contaminated with gasoline in the laboratory. Concentrations of 10–20% of lime, cement, and asphalt were added to the soil. A standard sample was chosen to compare the results obtained in the modified Proctor compaction, California bearing ratio (CBR), direct shear, and consolidation tests. It was found that the presence of more than 10% liquid low–density hydrocarbon affects plasticity, void ratio, friction angle, moisture content, dry density, and cohesion. According to the tests carried out, soils contaminated with concentrations lower than 10% of gasoline are recommended to construct the subgrade and sub-base layers in pavements. Finally, it was found that cement is the stabilizer that presented overall higher enhancements of the mechanical properties of the clayey gravel and sand soil among the three stabilizers. However, the results also show that depending on the soil use and specific parameter requirements, other stabilizers can be used.

在寻找土壤生物修复的替代方法时，本研究旨在在实验室中分析石灰，水泥和沥青作为稳定剂对被汽油污染的黏性砾石和沙土的影响。向土壤中添加了10–20％的石灰，水泥和沥青。选择一个标准样品来比较在改进的Proctor压实，加利福尼亚承载比（CBR），直接剪切和固结测试中获得的结果。研究发现，液态低密度烃含量超过10％会影响可塑性，空隙率，摩擦角，水分含量，干密度和内聚力。根据进行的测试，建议污染浓度低于汽油10％的土壤在人行道上建造路基和路基层。最后，结果发现，水泥是稳定剂，在三种稳定剂中，水泥能总体上提高粘土质砾石和砂土的机械性能。但是，结果还表明，根据土壤用途和特定参数要求，可以使用其他稳定剂。
