Laboratory Soil California Bearing Ratio CBR Testing Machine

Laboratory Soil California Bearing Ratio (CBR) Testing Machine

Product Description

CBR-III Digital CBR Testing Machine

I. Purpose and scope of application:

California bearing ratio (CBR) tester is used to test the bearing ratio of various soil, pavement base and bottom materials after making specimens in the specified test tube. This test is in accordance with ASTM d1883 and BS1377:4.

The maximum particle size of the mixture should be controlled within 25 mm and not more than 40 mmII.Main parameters of the instrument:

1. Test speed: 1.27mm/min(ASTM D1883)   1mm/min(BS1377:4). Fast speed: 15mm / min

2. Test force value: 50kN force value accuracy: 0.001kn

3. Penetration rod: end diameter: 49.63 ± 0.13MM(ASTM D1883)     50±0.5MM(BS1377:4)

4. Displacement sensor: 0-25mm, graduation value: 0.01mm, linearity: 0.3%.

III.Main features:

1. 7 inch color touch screen display, with curve display, data saving and printing.

2. The deformation recording point and loading speed can be set arbitrarily to meet the needs of different test standards.

3. It has data processing function and can automatically calculate CBR value.

4. Servo motor control, with software speed feedback, loading speed stepless adjustment.

5. Built in micro printer can print data stream list and test results.

Automatic CBR Test Machine is designed for performing laboratory evaluation of the CBR value of highway sub-bases and sub-grade, and determination of the strength of cohesive materials which have maximum particle sizes less than 19 mm.

This machine is suitable for test of soils and mix materials (the grain size of the soil is less than 40mm) compacted with CBR mold so as to confirm the bearing loading ability of pavement, roadbed subcrust as well as material layer of the roadbed to be designed. It consists of a twin column frame, proving ring, penetration bar, loading plate, micrometer, measuring device for swell increment etc. and easy to operate.

CBR Test Machine, Automatic
CBR Test 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.

Features of CBR 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.
