This paper presents the results of an experimental study in the laboratory of a local soil combined with cement ordinary Portland cement (C), fly ash (FA), and enzyme. Firstly, four mixed proportions of soil (S) and FA (i.e., S/FA = 100:0, 80:20, 65:35, 50:50) were tested in the laboratory to determine basic properties. Subsequently, a certain cement content was added to four mixtures to investigate the engineering properties of stabilized soil during the curing period of 7 days. Finally, for the DZ33-Enzyme stabilizer, the dosage of 1 L per 30 m3 compacted soil was continuously mixed to the optimum C-FA-S mixture to find out engineering properties, such as compressive strength, splitting tensile strength, elastic modulus, and California Bearing Ratio (CBR). Results indicated that soil mixture with S/FA = 65:35 ratio was selected for stabilized soil which yielded good performance in engineering properties. Adding DZ33-enzyme stabilizer and cement to the FA-S mixture significantly improved the strength of the soil and was satisfied as subbase, base layers in road construction based on current Vietnamese standards. The experimental data are expected to contribute satisfactorily for application in the subgrade, subbase, and base layers of road construction under the condition of materials shortage.
