Wholesale Gyratory Compactor For Asphalt Mixture ASTM D692 Manufacturer, Supplier

A rotary compactor for asphalt is a device used in the laboratory to simulate the compaction process of asphalt mixtures during road construction. It prepares asphalt mixture specimens by combining rotation and vertical pressure to evaluate their volume characteristics, mechanical properties, and construction performance.

Product Description

Product Description

Under constant pressure, fixed compaction angle and rotation speed, the asphalt mixture in the test mold is rotary compacted by kneading, simulating the rolling of the road surface by vehicles on site, so that the mixture reaches a dense state, accurately simulating the compaction state on site, and evaluating the compaction characteristics of the asphalt mixture.

Asphalt Gyratory Compactor is suitable for the rotary compaction method to form Φ 150mm or Φ 100mm asphalt mixture cylindrical specimens for laboratory use in the physical and mechanical properties test of asphalt mixture. The molded specimens are used for compression deformation strength, shear strength, splitting, rebound and other tests.

Structural Composition

Loading system: Usually composed of electronically controlled cylinders, pressure regulating valves, etc., with continuously adjustable pressure, and vertical loads are accurately applied through servo control.
🔄
Rotation system: The rotational motion is generated by a high-precision eccentric wheel system or other rotating mechanism. The rotation speed is generally around 30 rpm, and the angle can be accurately set and kept constant.
📏
Measurement system: Including displacement sensors, rotary encoders, etc., used to measure data such as rotary compaction displacement and specimen height change.
💻
Control system: With industrial touch screen, Gyratory Compaction Apparatus can display the process data such as the number of rotations, pressure, displacement, etc. in real time.

The asphalt compaction instrument consists of hydraulic pressure system, rotating base, demoulding system, data acquisition, data display, deformation, angle and other control systems. Connecting to a computer can analyze and calculate the test data, save data and display graphics.
