Introduction: This instrument is designed and manufactured in accordance with the requirements specified in the transportation industry standard JT/T 724-2008 "Rotating Compactor" and JTG E20-2011 "Test Code for Asphalt and Asphalt Mixtures in Highway Engineering" (T 0736-2011 "Method for Making Rotating Compaction Test Specimens (SGC) for Asphalt Mixtures" in the People's Republic of China, as well as the American Society for Testing and Materials ASTM D6925 standard and the American Association of State Highway and Transportation Officials (AASHTO T312 standard). It also incorporates advanced technology from various countries in the design and manufacturing of rotating compactors. Suitable for forming using electrically driven rotary compaction method Φ 150mm or Φ The compaction and shaping of 100mm (separately purchased) cylindrical specimens of asphalt mixture, emulsified asphalt, and cold recycled mixture for laboratory testing of physical and mechanical properties of asphalt mixture. Features: 1. Using high hardness and high-quality steel as the frame to ensure precise angle control. 2. Electric dynamic servo control adjustment can measure and display important parameters such as the angle of trial mold rotation, compaction pressure, specimen compaction degree, and number of rotations in real time during the compaction process. 3. The color display touch control system can be directly connected to a computer, and various curve charts can be displayed through an interface microcomputer. It can also achieve undisturbed connection with the touch screen to jointly control the instrument. 4. It is easy to set testing parameters such as rotation compaction angle, compaction pressure, rotation speed, and number of rotations, and to save, plot, and print compaction experimental results. 5. There are two operation modes to complete compaction molding: ① preset rotation times, and ② preset height. 6. Integrated built-in demoulder. Technical parameters: Working power supply: AC (220 ± 10%) V, 50Hz Rotary compaction displacement range: (0-250) mm Height range of formed specimens: (50-170) mm Rotation compaction displacement accuracy: ＜ 0.10mm Rotating compaction angle: (0-2) °, ± 0.02 ° adjustable, factory set to 1.16 ° ± 0.02 ° (internal angle), customizable for larger angles Rotary compaction pressure: (0-1000) KPa ± 3% adjustable, factory set to (600 ± 2%) KPa, customizable for larger pressure Rotating speed: (30 ± 0.3) r/min, customizable for continuous and adjustable speed Spinning frequency: (0-999) times Displacement measurement: (0-220) mm Trial mold size: standard configuration Φ 150mm, can be customized separately Φ 100mm Pressure application method: cylinder
