Model: WRT0719A

Description

The wheel rutting tester is used to determine the road asphalt mixture wheel-rutting resistance under high temperature, also it can test the asphalt mixture stability under high temperature at field. It’s kind of very common asphalt testing instrument.

Main 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 and displacement, time and temperature

PWM method on 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 constant temperature chamber.

Can do submerging test, sample surface temperature / water temperature/ sample internal temperature controllable, thus can perform test under different conditions
