Gyratory Compactor

LXY-170 Asphalt gyratory compactor

Model: LXY-170

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


The gyratory compactor is used to simulate 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.


Quality steel made for the main frame, guarantee precision angle control

Pneumatic type servo control

Color touch screen system, can directly connect with computer, computer interface can display various kinds of curve, non-interference connection with touch screen

Easy preset compaction angle, pressure, rotational speed, rotation times;

Real time display mould rotational angle, pressure, specimen density, rotational times;

Test results can be stored, printed

Two kinds of operation modes: 1. preset rotational times 2. preset height

Data interface: USB/RS232

Mould ejector built-in

Heating and thermal insulation function for working chamber (optional)

Can be used for emulsified asphalt and cold-regenerated mixture compaction test
