Analysis of the Characteristics of a Rotary Compactor
1. A high-hardness, premium-grade steel is used for the frame to ensure precise angle control.

Overview and Feature Analysis of the Rotary Compactor
The design of the rotary compactor incorporates numerous features aimed at ensuring operator safety and minimizing manual intervention when handling hot, heavy test molds filled with asphalt mixtures. The test molds can be slid directly from the workbench into the compaction chamber and then, after compaction, slid into a pneumatic specimen separator—all without requiring any lifting or raising motions. The compaction chamber is completely sealed, and its access door is fitted with safety glass, allowing operators to observe the compaction process through the glass. The door features automatic opening and closing mechanisms and is equipped with an interlock system to prevent it from being activated while closed. Additionally, an emergency stop button is provided for immediate shutdown in case of an emergency.

Instructions for Use of the Penetration Tester for Grouted Asphalt Mixtures
1. Demold the specimens that have been cooled and allowed to stand according to the specified procedures, ensuring that the side surface of the specimen serves as the test surface, and then reinsert the specimens into the test molds.

Several Key Features of the Asphalt Mixture Stability Tester
An automatic digital-display high-strength Marshall stability and flow value testing apparatus, characterized in that it comprises a digital-display pressure testing machine, two Marshall test molds, shims, a flow value sensor, and a signal switch. Specifically, the two Marshall test molds are installed directly above the center of gravity of the lower platen of the digital-display pressure testing machine and below the upper platen of the same machine. The two Marshall test molds are fitted together vertically to form a cylindrical cavity, and the flow value sensor is positioned on top of the Marshall test mold. The flow value sensor, the digital display screen of the digital-display pressure testing machine, and the hydraulic sensor are each connected to the signal switch. A shim is placed between the upper Marshall test mold and the upper platen of the digital-display pressure testing machine.
