Introduction: The SYD-7981 asphalt mixture shear compactor uses shear compaction molding technology to make asphalt mixture specimens. During the molding process, the horizontal movement of the two side walls of the test mold causes the mixture to be subjected to shear force, while the vertical direction applies a load to the specimen. Under the joint action of the two, an ideal specimen with regular aggregate layout and uniform density distribution is obtained. Features: 1. The quality of the formed specimens is excellent, overcoming problems such as uneven force distribution between the upper and lower layers during fan-shaped rolling, differences between different specimens during rotary compaction, and uneven distribution of specimens during compaction. 2. The length, width, and height dimensions of the formed specimen are 450mm x 150mm x (120-185mm). One specimen can be cut into (4-6) prism/small beam bending specimens, or (1-4) cylindrical specimens can be drilled, or other required specimens can be cut and drilled. All cut or drilled specimens have good consistency, reliable test results, and scientific and reasonable comparative tests. 3. The SYD-7981 asphalt mixture shear compactor is a versatile machine that can be used in conjunction with our company's asphalt mixture cutting machine and multi-functional asphalt mixture coring machine to obtain asphalt mixture specimens of various specifications in JTG-E20 "Test Regulations for Asphalt and Asphalt Mixtures in Highway Engineering". Moreover, the quality of the specimens is better and the test results are more accurate. 4. Adopting a high hardness and high-quality steel frame structure, the instrument is sturdy and stable, with good dynamic stability. 5. The horizontal shearing effect is controlled by a high-precision servo motor, and the shearing angle is continuously adjustable, up to a maximum of 4 °. 6. Display real-time data, including shear force, compressive strength, specimen height, and display compaction curve, while saving relevant parameters. 7. Using specialized trial molds and loading tools to ensure even distribution of loading materials; After the molding of the specimen is completed, it can be automatically demolded. Technical parameters: Working power supply (reference): AC220V/50Hz, 5000 Maximum shear angle: 4 ° Frequency: 3.7 cycles per minute Maximum contact pressure: 2MPa Compaction density: controllable density during molding
