1. Purpose and overview

1. This instrument is designed and manufactured according to JTJ 059-95 standard, and is suitable for on-site measurement of various soil-based materials CBR values  on highways.

2. The working principle is to use a truck with a rear bearing weight not less than 60KN, load it with a jack, and calculate the CBR value of the soil foundation site through the measured penetration  by the penetration rod and the load weight measured by the force measuring ring.

2. Main technical parameters

1. Hydraulic jack: 100KN with ball seat

2. Force measuring ring: 60KN

3. Penetration rod: Φ50mm, length 200mm

4. Bearing board: 1.25Kg/4 pieces

5. Measuring device: platform and dial indicator
