Investigation of the effects of different laboratory compacting methods on the properties of cement stabilized materials

Cement stabilized materials have been attractive for pavement base construction. There are many factors influencing the properties of cement stabilized materials, including the soil type, mix proportion, the compaction degree, etc. Among these variables, the compaction process plays a significant role in the final behavior of these materials. That is because the cement stabilized mixture should be compacted to a certain density to achieve maximum strength. Optimum compacted materials may reduce the moisture susceptibility and increase the durability. The materials can be mechanically compacted by static or vibratory pressure. However, due to the variable characteristics of the soil or aggregate, it is essential to choose the appropriate compacting methods for each type of material. Therefore, this research is conducted to investigate the effect of compaction methods on the properties of cement stabilized materials. Three typical types of soil, i.e. sand, sandy clay and clay are stabilized with cement and RoadCem additive to evaluate the compressive strength and indirect tensile strength. Proctor and vibratory compaction technical are applied to each type of stabilized soil. Based on the experimental results, the mechanical performance of cement stabilized material samples obtained through these two compaction methods is compared. Consequently, the appropriate compaction technique for specified soil types is determined.
