Automatic Wheel Tracking Tester HTHY-0719

Product Introduction

This equipment is designed to determine the high-temperature rutting resistance performance of asphalt mixtures. It is used as a supplementary evaluation tool for asphalt mixture mix design and can also be applied for field evaluation of the high-temperature stability of asphalt mixtures.

Key Features

Multi-point data acquisition for improved test data stability

Temperature, displacement, and pressure sensors are linearly calibrated to ensure excellent linearity throughout the full measurement range

Easy and convenient pressure adjustment

Standard

JTG 3410-T0719

Product Features

Equipped with high-precision displacement sensors with an accuracy better than ±0.01 mm.

Controlled by an industrial-grade tablet PC for simple and user-friendly operation.

Automatic temperature control with automatic generation and storage of test results after completion of the test.

Equipped with absolute temperature sensors for temperature measurement, providing a wide temperature control range, high accuracy, and excellent stability.

PWM-based PID temperature control effectively prevents temperature overshoot and improves temperature control stability.

The chamber is equipped with a forced air circulation and mixing system to achieve more uniform temperature distribution.
