The OJ-type field CBR testing device S-180 is a simplified OJ-type field CBR testing machine that uses an oil jack with a Bourdon tube pressure gauge.
The hydraulic jack uses a Bourdon tube pressure gauge with a capacity of tons and a minimum scale of 100 kg.

It is used for a test that directly measures the load required to penetrate the soil to determine the magnitude of bearing capacity and evaluates the bearing capacity characteristics relatively based on the ratio to a standard load.
It is used for a test that directly measures the load required to penetrate the soil to determine the magnitude of bearing capacity at the site, and evaluates the bearing capacity characteristics relatively based on the ratio to a standard load. The field CBR test directly measures the load required to penetrate a standard-sized loading piston into the soil to determine the current magnitude of bearing capacity of the subgrade or base course at the site, and evaluates the bearing capacity characteristics relatively based on the ratio to a standard load.
