Small wheel for asphalt samples.



The apparatus consists of a steel plate casing with stainless steel interior 1.4301 and hinged cover with viewing glasses. Two measuring places with rolling wheel units guided in  bearing elements and driven by a frequency controlled motor with omega-synchronous-belt-drive are installed. Load is applied via a lever system.



The inside can be heated either with water or with a hot-air blowing system.



To enable the installation of samples into the testing place, both rolling wheel units can be stopped in a parking position outside the testing area. The two sample base plates of the machine are prepared for the installation of either mould spanner sets (20-4020..23) or plaster moulds (20-4015..16).



Included are two easily interchangeable rolling wheels with rubber coating. Stainless steel rolling wheels 20-4000E100 are available on request. Two motorized lifting units controlled by the integrated software are used to sink down the wheels at the beginning of a test and to lift them up afterward.



The whole process including heating, registration of test temperatures, number of overrollings and tracking depths is software controlled with the possibility of print-out and selectable testing programmes. The user himself can create and memorize his own test sequences and programmes.



Supplied with integrated input/output unit with touch screen. Optionally the input can also be effected using a keyboard. Mould spanner sets 20-4020..23 or plaster mould sets 20-4015..16 are not included and be ordered in addition.
