Asphalt Wheel Tracker

Model: LY-0719


Description

The wheel tracker is used to determine the paving asphalt mixture wheel-rutting resistance under high temperature, also it can test the asphalt mixture stability under high temperature in field. It's kind of common asphalt mixture testing equipment. Normally the test temperature is 60 degree C, wheel pressure is 0.7Mpa.


Features

Floor type, PC control, automatic temperature control, automatic timing, real-time display of rutting displacement, automatic recording of displacement graph, test report print.

Synchronous graphical indicating of time & displacement, time & temperature

PWM method for temperature control, high temperature stability, absolute temperature sensor acquisition, no temperature drift in long time test

High definition A/D, D/A module guarantee accuracy of displacement and temperature measuring; external cycling heating guarantee uniform temperature in the constant temperature chamber.
