This instrument is based on the transportation industry standards of the People's Republic of China JT/T 724-2008《 Rotary compactor》, JTG E20-2011《 In the test procedures for asphalt and asphalt mixtures for highway engineering T 0736-2011《 Method for making rotary compacted specimens of asphalt mixture ( SGC）》 Requirements for the provisions, and the American Materials Experimental Association ASTM D6925 Standard, United States Association of Highway and Transportation Officials AASHTO T312 Standards, etc., and absorb the advanced technology of rotary compactors in various countries, and are designed and manufactured through their expertise. Suitable for forming by electrically powered rotary compaction method φ150㎜or φ100㎜(Purchase separately )The compaction molding of asphalt mixture, emulsified asphalt and cold regenerated mixture cylindrical test pieces are provided for laboratory testing of the physical and mechanical properties of asphalt mixture.

1. Main technical characteristics
1、High-hardness and high-quality steel are used as the frame to ensure accurate angle control.
2、The electrically powered servo control adjustment can measure and display important parameters such as the rotation angle of the test mold, the compaction pressure, the compaction degree of the test piece, the rotation number of the test piece during the compaction process.
3、The color display touch control system can be directly connected to the computer. Through the interface of the microcomputer, various curve charts can be displayed and disturb-free connections with the touch screen, and jointly implement control of the instrument.
4、It can easily set the test parameters such as rotation compaction angle, compaction pressure, rotation speed, and rotation times, and save, draw, and print the compaction experimental results.
5、Compact forming is completed with two operating modes: ① Preset number of rotations, ② Preset the specified height.
6、Interface configuration: 1 USB Interface, 1 RS232 interface.
