The asphalt binder tester consists essentially of a high precision apparatus combining an ignition oven to a continuous weighing system to monitor the loss of weight of the asphalt sample and to automatically determine, at the end of the test, the binder content and percentage. An independently controlled auxiliary afterburner chamber significantly reduces the furnace emissions. The asphalt binder tester is supplied complete with double sample basket/safety cover, extraction fork and 3 meters of metal exhaust pipe.

Asphalt binder tester for most people is absolutely a very new thing, many people do not even know the test of asphalt binder content is what the purpose. One might think that simply putting asphalt on the road would do the trick, but that's not the case. So what is the asphalt binder testing machine?

The importance of an asphalt binder testerIn the 1980s, the asphalt binder tester industry began to focus on the growing demand for a better understanding of the rheological properties of asphalt binders. Prior to this, basic flow characteristics were mainly measured by viscosity tests. For traditio

Chocolate pudding, synthetic rubber, toothpaste and asphalt… At first glance, these items seem to be randomly selected. Although it may not be obvious, these products have a common, basic characteristic-their rheology, or flow and deformation, can be measured with one instrument.

Modified asphalt has been an area where the MATC project investigates implementation challenges and shares experiences with the asphalt community. The asphalt binder tester is involved in several field projects evaluating modified asphalt binders and mixtures. The main challenge in describing the properties of modified asphalt binders involves a suitable asphalt binder tester test method. Observations from field studies indicate that the concentric cylindrical geometry provides a promising tool for characterizing the rheological properties of modified asphalt binders.

The asphalt binder tester has long been involved in the improvement of AASHTO and industry standards. For example, the asphalt binder tester incorporates new and innovative procedures, such as core-cylindrical geometry, to evaluate new materials such as ground tire rubber modified adhesives (modified adhesives).
