2021-09-14
Characteristics of the Asphalt Mixture Compaction Tester
It can perform automatic counting, automatic compaction, and automatic shutdown. It also features a hammer-hanging bracket and a manual handle for easy lifting of the hammer. The semi-automatic mold installation makes it even more convenient to install and remove molds.
Operating Procedures for the Asphalt Mixture Compaction Tester
a. Before each compaction, the compaction punch, the inner walls of the mold, and the base of the mold should be coated with machine oil.
b. Open the safety door, lift the guide rail slider and the weight hammer, and use the safety control lever to lock the compaction head in place.
c. According to the standard procedure, place the thoroughly mixed asphalt mixture into the test mold, then push the test mold onto the positioning pins on the steel plate platform and securely lock the mold.
d. Lift the guide rod and the weight hammer, flip up the safety lever, lower the compaction plunger, open the safety door, and press the start button to begin the compaction process. The machine will automatically shut down once the preset number of cycles is reached.
Precautions for Using the Asphalt Mixture Compaction Tester
1. The counter counts in a forward-counting manner.
2. The next time you strike, first press the reset button and then press the start button.
3. When compaction is in progress and the machine needs to be stopped or malfunctions, you can press the stop button to halt the compaction apparatus.
4. The chain tension should be checked regularly, and if its sag exceeds 10 mm, it should be adjusted.
5. Do not start the compaction machine when no mixture is loaded. When not in use, place cotton yarn or shredded paper inside the test mold.
6. Regularly lubricate the chain and the sliding parts of the weight hammer.
7. After each compaction is completed, the test mold, compaction rammer, and steel plate platform should be promptly cleaned and properly disposed of.
