Automatic Soil CBR Press Testing Machine

Short Description:

Product Detail

Product Tags

CBR Press Testing Machine is used to determine the strength of subgrade soils and base course materials by measuring the pressure required to penetrate a soil sample with a plunger of standard size. This penetration resistance is compared to the penetration resistance of a standard crushed stone material. The ratio of the two penetration resistances is the California Bearing Ratio, which is used to assess the immediate bearing index of the soil for pavement design, road construction, and foundation engineering.New Touch Screen controller with rigid and compact design. By using a server Drive System to achieve more reliable and highly accurate testing results.

The California Bearing Ratio (CBR) soil tester is an essential instrument in civil engineering, particularly in road and pavement design and construction. This tester is used to assess the strength and bearing capacity of soils, which is crucial for ensuring the stability and durability of infrastructure projects.

Features of CBR Press Test Machine
Automatic Load Application: Automate the process of applying incremental loads to the soil sample. This automation ensures consistent and repeatable testing conditions, reducing human error and increasing efficiency.
Rapid Plate Adjustment: You can easily and quickly change the position of the machine’s parts for different tests.
Data Recording and Analysis: Measuring penetration depths at various load increments and calculating the California Bearing Ratio based on these measurements. Data analysis features can provide insights into the strength and bearing capacity of the soil.
User-Friendly Interface: Large touchscreen display for viewing real-time graphs and test data, allowing operators to easily set up tests, monitor progress, and access test results with minimal training.
Portability and Durability: It’s a small machine that you can put on a bench, saving space in the lab. Designed to be portable, and suitable for use in field conditions. Portability enables on-site testing for assessing soil conditions in construction.
Safety Features: There’s a button to stop everything in case of an emergency, keeping everyone safe.
Low Noise and Vibration: Operates quietly with minimal vibrations to avoid disturbance in the lab environment.
