Standards
1. AASHTO T324 Standard method of test for Hamburg wheel-track testing of compacted hot mix asphalt(HMA)
2. European Union EN 12697-22 Bituminous mixtures - Test methods for hotmix asphalt - Part 22 Wheel tracking
The Hamburg wheel tracking tester is specially used for determine the rutting and water sensitivity of hot mix asphalt mixtures; Can test the permanent deformation rate of asphalt mixture under the action of moving load; Early damage caused by insufficient aggregate structure, insufficient binder strength, or water damage can be determined by measuring the rut depth of asphalt mixture and the number of loading cycles at the time of failure; The immersion test method can also be chosen to evaluate the impact of water damage on asphalt mixtures.
1. Computer control, simple and convenient operation.
2. Using high-precision displacement sensors, the accuracy is better than ± 0.01mm over a large range.
3. Automatic temperature control, automatic generation and saving of test results.
4. Using an absolute temperature sensor to collect temperature, the temperature control range is wide, the accuracy is high, and the stability is good.
5. Using PWM modulation for temperature PID control to ensure no overshoot in temperature.
6. The linear modulation of temperature sensors and displacement sensors ensures full range linearity.
7. The data collection method is to collect 11 points within a symmetrical 210mm area at the center of the trial mold and calculate their average deformation as the deformation amount for calculating the test results.
8. There are two options for stopping the experiment: stopping by time or stopping by number of turns.
9. Adopting an open workbench for easy installation and removal of trial molds.
10. The whole machine is made of high-quality stainless steel, which is beautiful and easy to clean.
