Introduction and Parameters of the Asphalt Mixture Stability Tester
2022-01-05
Introduction to the Asphalt Mixture Stability Tester:
1. The entire experiment is automatically controlled by the instrument, and automatic measurement eliminates various human errors and prints out the experimental results.
2. Equipped with an automatic overpressure protection function (if the pressure exceeds the set limit, the display will show HHHH.HHHH, and the instrument will automatically stop pressurizing), preventing damage to the instrument caused by overpressure.
3. The instrument shall conform to the “Test Procedures for Highway Engineering and Asphalt Mixtures” issued by the Ministry of Transport of the People’s Republic of China under Document No. 93-2-3.
4. The intelligent measurement and control module can be paired with the loading module of a conventional Marshall testing machine.
(2) Technical parameters of the asphalt mixture stability tester:
1. Pressure measurement range: 0–30 kN; [3 tons] suitable for specimens with a diameter of 101.6 mm.
2. Pressure measurement range: 0–50 kN; [5 tons] suitable for specimens with a diameter of 152.4 mm.
3. Flow value measurement range: 0–15.00 mm (in practice, it can reach beyond 15.00 mm);
4. Data acquisition rate: 45,000 times/second;
5. The instrument can store experimental results for 15 specimens.
6. Operating voltage: 220V; 50Hz;
7. Operating temperature: 5–35℃; it is recommended to use the product at an ambient temperature of 10–30℃.
