**Asphalt Concrete Universal Testing Machine - LSY-4**
The **LSY-4 Asphalt Concrete Universal Testing Machine** is a high-performance device designed for comprehensive mechanical testing of asphalt concrete materials. It is widely used in laboratories and on-site applications to evaluate the axial compressive strength, strain, and deformation modulus of asphalt concrete samples. This machine complies with the **DL/T5362-2006** standard for hydraulic asphalt concrete testing procedures, making it ideal for analyzing both molded specimens and core samples drilled from real-world structures.
**Key Features:**
- **Advanced Control System:** The machine utilizes an advanced **DSCC-1 digital closed-loop control system**, ensuring precise and reliable test results. The system supports dynamic display of the test process, curve plotting, and post-test data analysis through a dedicated graphic processing module.
- **High Rigidity Frame:** The machine features a rigid gantry structure made from high-strength steel, ensuring stability and accuracy during testing. The motor-driven moving beam allows for smooth and controlled loading, whether in tension or compression.
- **Versatile Testing Capabilities:** It can automatically measure and calculate critical mechanical properties such as **ReH, ReL, Rp0.2, Fm, Rt0.5, Rt0.6, Rt0.65, Rt0.7, Rm, and E**. These parameters are essential for evaluating the performance of asphalt concrete under various stress conditions.
- **Compliance with International Standards:** The equipment supports testing according to **GB, ISO, DIN, ASTM, JIS**, and other global standards, providing accurate and comparable data for international projects.
