🛠️ Key Features & Applications

Versatile Testing Capability:

This equipment is designed for both on-site and indoor testing. It allows for direct cutting after drilling on site without the need to extract the core sample. It is also suitable for making standard samples using compaction instruments for the highway industry, adhering to national standards (using a 5kg steel hammer for 75-cycle compaction).

Advanced Control System:

Equipped with microcomputer acquisition and servo motor speed control. The LCD provides real-time display of interlayer adhesive torque, shear force, and deformation peak values. The system supports data calculation, analysis, storage, and professional curve export functions.
