HTHY-0730

It is mainly used in the laboratory to evaluate the properties of asphalt mixture. The self-developed control system and temperature control system enable the equipment to meet the requirements of multiple tests, and multiple tests can be completed with different fixtures.

APPLICATION

l  Asphalt mixture bending test

l  Crack growth performance test of asphalt mixture (Semi-Circular Bend method)

l  Marshall stability test

FEATURES

l  Using high-hardness high-quality steel as the frame, the structure is simple and stable.

l  The adopted LVDT has high precision and stability.

l  Adopt customized special high-performance, high-stability pressure sensor.

l  The temperature sensor, displacement sensor and pressure sensor are linearly modulated to ensure the accuracy within the full scale.

l  The position of the sensor is reasonable, and the test result is more accurate.

l  Test results can be automatically generated and saved, and related curves can be displayed.

l  Equipped with a constant temperature chamber with cooling and heating functions.

l  Using PWM modulation method for temperature PID control, wide temperature control range, high precision and stability.

l  Test fixtures can be customized for different tests.

l  16-bit adaptive data acquisition system with a sampling frequency up to 5KHz.
