In the field of road engineering, the bond strength between the layers of the road surface is the core indicator that determines the overall strength and durability of the road structure. Once the interlayer bonding fails, it can cause road displacement and cracks, and in severe cases, structural collapse, posing a threat to driving safety.The intelligent pavement interlayer adhesion pull-out tester, as a high-precision instrument designed specifically for detecting this key indicator, is becoming a crucial 'detection tool' in road construction, maintenance, and quality control.

　　The core function of this tester is to accurately measure the bond strength between pavement material layers by simulating actual load conditions.Its working principle is based on real-time monitoring of 'pulling force deformation': the prepared pavement material sample is fixed on the pulling platform of the testing machine, and a constant rate of pulling force is applied to the sample through a servo system; The built-in high-precision sensor synchronously collects the tensile force value and sample deformation data. When the interlayer bonding force reaches its limit, the maximum tensile force at the moment of failure is recorded - this value is the key quantitative indicator of interlayer bonding strength. The entire process automatically adjusts parameters through an intelligent control system and displays the force displacement curve in real time, ultimately generating a detailed report containing testing conditions, failure types, data comparisons, and other information, providing a scientific basis for analyzing the quality of interlayer bonding.

　　Compared with traditional detection methods, the advantages of the intelligent pavement interlayer adhesion pull-out tester are significant:

　　Firstly, high precision and intelligence.Using servo motor drive and ball screw lifting and loading, coupled with high-sensitivity force sensors, to ensure precise capture of small deformations and pulling forces;

　　Secondly, multi scenario adaptation.Support indoor standard specimen testing and on-site pavement in-situ inspection, and can cover various interlayer combinations such as asphalt water stable layer, waterproof layer concrete, etc. by replacing the pull-out head and adjusting the loading mode (adjustable speed of 0.01-50mm/min);

　　Thirdly, efficient data management.The 7-inch touch screen displays real-time curves, and the micro printer outputs results on site. Some models also support USB data export and cloud storage functions, making it easy to compare historical data and trace engineering.

From the selection of interlayer bonding materials in road construction projects to the diagnosis of pavement quality during maintenance stages; From the verification of new bonding technologies by scientific research institutions to the quality acceptance by third-party testing institutions, the intelligent pavement interlayer bonding force pull-out tester has become a key tool for safeguarding the safety of pavement structures with its precise, efficient, and flexible characteristics, providing solid technical support for improving road service life and driving comfort.
