When soil properties are unstable, soils used in construction need to be tested (e.g., soil compaction using a rammer). Therefore, the production and shipment of stable quality soil is important to reduce on-site burden and maintain stable construction quality. Thus, by focusing on a water content ratio that is highly correlated with the fine fraction content and strength, we adopt a device to measure the water content ratio as an alternative to conventional soil tests. This test aims to develop a technology to produce stable quality mixtures (sandy soil + clayey soil) by automatically measuring the water content ratio of soil to determine the proper combining ratio.
