Hamburg Wet/Dry Wheel Tracker

Hamburg (Immersion) wheel tracking test is used to evaluate the resistance to rutting and moisture susceptibility of asphalt mixtures. AASHTO-T324 is the generally referred to test standard, although many states modify this procedure to meet their specific requirements. Outside of the U.S. both AASHTO-T234 and EN12697-22 are followed.

What differentiates the Hamburg from other wheel tracking methods is the use of water to condition the temperature of the specimens rather than air. It is believed that the water, in some tests, strips the aggregate which creates a tertiary phase that is distinct from the permanent deformation which occurs in dry wheel tracking tests. The use of stainless steel wheels on a weighted cantilevered arm, in conjunction with water has led some people to refer to Hamburg wheel tracking as a ‘torture test’. Certainly it is the case that less well constructed machines will shake to pieces due to the aggressive nature of the test. The Cox Hamburg is manufactured in California from thick solid stainless steel. Painted steel panels and parts are not an option for the Hamburg test. Our Hamburg is built to last decades not just a couple of years, which is why it comes with a five year warranty. A rigid frame construction is also essential for accurate results. Cheaply produced machines will flex machine and quality of test results go hand in hand. and vibrate with deeper rut depths. Quality The Cox Hamburg will output more precise and accurate results than any other Hamburg machine – guaranteed.
