Marshall CBR Universal Digital Servo Pavement Material Strength Tester/Pavement material strength Testing Apparatus

20B Type

Pavement material strength comprehensive tester has the advantages of stable loading, low noise, large screw stroke, simple operation, etc. It is an instrument required by highway construction units, colleges and universities and quality inspection departments. The instrument is equipped with overload protection, automatic speed change, no need to manually shift the gear lever to change the test speed, 1/50mm in the controller can be switched, the machine is equipped with other related fixtures to perform multiple tests, such as the compression resistance of cement and lime stabilized soil Strength, splitting strength, resilience modulus and other tests, Marshall test of asphalt concrete, bearing ratio (CBR) test of subgrade soil and various pavement materials, etc. Data can be uploaded to the computer (the equipment factory defaults to 4 types of tests: CBR  test, Marshall stability test, unrestricted compressive strength test, other tests, standard dual pressure sensors, dual displacement sensors)

1. Maximum load: 200KN;
2. Working stroke: 200mm;
3. Working power supply: this machine adopts 380V, 220V independent power supply working mode
AC380V 50Hz (the host uses a three-phase power supply, no neutral line is required; the host is equipped with a phase sequence protector, if the host does not work after the power is connected, and an alarm sounds, only any two live wires can be exchanged), the controller is 220V.
4. Power of the whole machine: 1Kw:
5. Ascent rate: 1mm/min and 50mm/min two gears (automatic selection); there is a delay of about 6 seconds when switching from high speed to low speed, which is a normal phenomenon.
6. Dimensions: 550X650X1550mm

20A Type

Pavement material strength comprehensive tester has the advantages of stable loading, large screw stroke, simple operation, etc. It is an instrument required by highway construction units, universities and quality inspection departments. This machine is equipped with other related fixtures and can perform multiple tests, such as the compressive strength, splitting strength, resilience modulus of cement and lime stabilized soil, the Marshall test of asphalt concrete, the bearing ratio of subgrade soil and various pavement materials (CBR) test etc. Note: This product can only be used for pressure test, other tests need to be equipped with corresponding accessories.

1. Maximum load: 200KN;
2. Working stroke: 200mm;
3. Working power supply: AC380V 50Hz (the host uses a three-phase power supply, no neutral line is required; the host is equipped with a phase sequence protector, if the host does not work after the power is connected, an alarm sounds, only any two live wires are required to adjust)

20C Type

This machine uses advanced computer technology combined with high-precision sensor technology, simple operation, accurate test data, and stable performance. The instrument is equipped with overload protection. The instrument automatically tests and records automatically. This machine mainly adopts two-column support, and its mechanical structure is reasonable, so as to ensure the accuracy of the instrument. The design is simple and generous. After installing the pressure sensor, it can be used to determine the unconfined compressive strength of various binder stabilized soil specimens. , CBR test, Marshall stability test, and other tests that require vertical load to be applied, with standard dual pressure sensors and dual displacement sensors.

1. Touch color screen control, servo motor drive.
2. Maximum rated load: 200KN
3. Test speed: 0.5mm-50mm (stepless speed adjustment is possible)
4. Pressure measurement range: 0-200.0KN
5. Displacement measurement range; 0-25mm
5. Working voltage: 220V
