Automatic rutting tester (three-wheel scientific research high-end type)

ASP-0719C-2 automatic rutting tester (three-wheel scientific research high-end type)

Product Introduction

ASP-0719C-2 automatic rutting tester is designed and manufactured in accordance with the requirements stipulated in T0719-2011 "Asphalt Mixture Rutting Test" in the People's Republic of China industry standard JTG E20-2011 "Test Procedures for Asphalt and Asphalt Mixtures in Highway Engineering".

It is suitable for the measurement and scientific research of the high-temperature anti-rutting ability of asphalt mixtures, and can also be used for high-temperature stability testing and research of on-site asphalt mixtures.

Technical features

1. Each of the three wheels is designed with independent test wheel pressure automatic loading, automatic testing and real-time display technology, which facilitates users to set the loading pressure as needed and monitor real-time pressure, providing a more convenient pressure loading method for scientific research and obtaining more reliable scientific research. data.

2. During the test, the color display screen displays the "time and displacement" and "time and temperature" change curves in real time, providing a complete scientific basis for users to study the rutting characteristics of asphalt mixtures.

3. The studio adopts the external circulation heating working mode and is designed with a hot air circulation system to ensure that the three rounds of tests are completed under uniform and consistent temperature fields, making the test data more valuable for scientific research.

4. Equipped with an onboard A4 laser printer, test results can be printed without using a computer, providing convenience for users to instantly save test data and information.

5. It has the anti-blocking protection function of the test wheel motor and the heating and overheating system protection function to maximize the reliability of the instrument's operation.
