HTNJ-1 intelligent pavement interlayer torsional shear tester

Product Information

The study of the characteristics of interlayer bonding materials in asphalt pavement structures has been a hot research topic both domestically and internationally in recent years. Insufficient tensile and shear strength of asphalt surface layers can easily lead to pavement damage phenomena such as displacement, crushing, and rutting. However, due to the lack of regulations, various corresponding testing equipment developed by various units cannot adapt well to the on-site working environment. After careful investigation of the on-site working environment and customer feedback, our company has developed a brand new set of pavement interlayer bond strength testing equipment (including pavement interlayer bond pull-out tester, pavement interlayer direct shear tester, pavement interlayer torsional shear tester, and pavement interlayer oblique shear tester). These devices extensively use common components and structures, share testing software and control systems, and are equipped with specially designed fixtures (customizable) to complete on-site tests (or indoor tests) of tensile strength and shear strength. Compared with products on the market, they are lightweight and easy to use, with built-in axial loading mechanism (no need for jacks and reaction frames during on-site testing, and no need to use car rear axles, etc.), built-in power lithium battery power box, no need for generators and car batteries, control system comes with a 7-inch color touch screen, and also comes standard with a wireless connected tablet computer (9.3-inch). The testing software is fully functional, with features such as data curve saving and report printing. Whether in terms of functionality or configuration, it comprehensively exceeds similar products on the market. Product. At the same time, the product is compatible with our cloud connection protocol and can upload test data to cloud data for remote data sharing, viewing, printing, and more. This instrument is applicable to JTG E60-2018 "On site Testing Regulations for Highway Roadbeds and Pavements" and JTG3410-2025 "Testing Regulations for Asphalt and Asphalt Mixtures in Highway Engineering".

Product Features:

1. Integrated body design, with control system integrated onto the body.

2. The body is equipped with a temperature digital display, which can read the on-site temperature.

3. Stepper motor driven loading, with speed closed-loop and stepless speed adjustment; High subdivision drive design, low-speed vibration free.

4. The main controller adopts a 7-inch color touch screen with a friendly and beautiful interface, equipped with lower limit protection and overload protection.

5. The user interface is a 9.3-inch Windows tablet that communicates with the main controller via WiFi (wireless local area network).

6. Standard 100mm and 150mm shear test fixtures (other sizes of fixtures can be customized).

7. Optional diagonal shear test fixture is available to complete the diagonal shear test.

8. Pulse handwheel manual loading handle, with no resistance during manual loading.

9. The user testing software can complete testing operations, save curve data, print reports, etc. (The printer is provided by the user themselves). The universal testing software can input report information such as test number, test type, test parameters, sample information, bonding material information, road surface information, temperature, and tester name. The ACCESS database can be used to save test parameters, test data, curves, etc., with no limit on the number of saved records.

10. It has cloud storage function. The local test data can be automatically uploaded to the cloud database, and registered users can view the test results, curves, and any other information remotely through specialized software. (Optional)
