The electronic pavement material strength testing machine is suitable for the axial force of inorganic binder specimens under uniaxial compressive stress.

Determine the unconfined compressive strength of specimens of inorganic binder stabilized materials (including stabilized fine soil, medium soil and coarse soil).

The flexural strength of inorganic binder stabilized materials was determined, and the basic parameters were provided for the loading standard determination of the flexural strength test of inorganic binder stabilized materials. The three-point compression method was used in the test.

The bending and tensile rebound modulus of inorganic binder stabilized material under static load was measured by three-point loading method.

Performance features:

1. It is mainly composed of host compression, bending and pulling mechanism unit, automatic control system unit, computer and special software data acquisition system unit;

2. The device uses a servo or variable frequency motor to drive the cantilever's up and down movement through a transmission mechanism, enabling the loading process for testing. It employs a fully digital closed-loop control system for both control and measurement. A computer is used to dynamically display the test process and the test curve, as well as to process the data. After the test, the data can be reanalyzed and edited, ensuring that the product performance meets the required standards.

3. Function

(1) Constant load force to collect displacement and deformation;

(2) Constant displacement to collect force value and deformation, peak tracking can be measured, residual force value can be measured;

(3) Cylindrical specimens: φ150×150mm; φ100×100mm (used for compressive strength deformation splitting test);

(4) Static pressure forming test mold and bending device: specification optional.
