This decade, a lot of soil stabilization research, especially expansive soils, uses nano materials. This is because many regions in Indonesia have expansive clay soil types, one of which is in Cilin Village, Bandung City, West Java Province. Expansive soils have low soil carrying capacity in high water table conditions. This condition surrounded the building above it. Disadvantages due to low carrying capacity of expansive soil, stabilization is needed to increase soil carrying capacity. It's just that the procurement of micro materials is very expensive. For this reason, this paper will explain the effectiveness of nano materials when compared to micromaterials. The main focus that will be discussed in this paper is how to compare the value of laboratory unsoaked CBR between micromaterials and quicklime nanomaterials in expansive soils. The research was conducted at the Bandung State Polytechnic Laboratory. This study used a stabilization method by adding 2% lime to each particle size. The procurement price of nanomaterials is Rp. 2,500,000 and micromaterials Rp. 1,500,000. The CBR test result obtained is native soil is 8.49; mixed soil 2% lime micromaterial is 9.01; and the soil mixture of 2% lime nanomaterial is 9.22. The difference in CBR value is only 0.21, so the more effective result is the unsoked condition of adding 2% lime micromaterial at a cheaper price.
