Asphalt Mixture Rotary Compactor

In the laboratory, simulating the volume properties and engineering attributes of actual pavement materials, the test piece is rotated at a uniform circular cycle at an eccentric angle under three main technical conditions: constant vertical pressure, constant compaction angle, and specified compaction speed, using the rubbing method. After constant pressure compaction, the eccentric angle is removed, and the constant pressure rotation is leveled to complete the experimental process of preparing cylindrical specimens of hot-mix asphalt mixture.

Description

Applications

In the laboratory, simulating the volumetric properties and engineering attributes of actual pavement materials, using a kneading method under three main technical conditions: constant vertical pressure, constant compaction angle, and specified compaction speed. The specimen undergoes uniform circular periodic rotation at an eccentric angle. After constant-pressure compaction, the eccentric angle is removed, and constant-pressure rotation is performed for leveling, completing the experimental process of preparing cylindrical specimens of hot-mix asphalt mixture.

The compaction angle specified in this standard refers to the effective internal angle during the test with the rotary compaction instrument.

Structure

The rotary compaction instrument mainly consists of a reaction frame, a loading device, a rotating base, a force measuring device, a displacement measuring device, a computer control system, and a mold. A structural diagram of a rotary compaction instrument that uses electronic-mechanical integration technology is shown.
