Superpave Gyratory Compactor

LXY-150 ASTM AASHTO asphalt gyratory compactor


Model: LXY-150

Standards: UNIEN 12697-10/UNIEN12697-31/ ASTMD6925/AASHTO T312


The gyratory compactor is used to stimulate the real paving works situation of field, thus to test the asphalt compaction performance, evaluate the asphalt mixture density characteristics, so as to supply technical reference for asphalt mixture mix design, quality control and tests.

It uses quality steel as the main frame, PID control for precise pressure control, linearity transducer measure height, precision centrifuge system generate rotational movement, can keep constant rotation angle and accuracy after easy preset.


l   Completely conforms the FHWA SUPERPAVE Standards, features safe and reliable work performance

SIEMENS PLC as the core control unit, features perfect protection function, can work even under complicated condition

7” industry touch screen, friendly Human-machine interface, easy parameters setup, real time display testing data, test data can be saved as Excel format and can be downloaded;

Pressure device, transducers, bearing and other important parts are original imported products;

Linear actuator loading mode for fast response speed

Full English operation interface
