Method and device for simulating the working of a thick coating material subjected to the action of rolling loads

摘要

The invention relates to a method and device for material fatigue tests by cleavage testing. A cylindrical test piece 1 of the material to be tested is subjected to a periodically repeated cleavage testing F at the lateral surface of the test piece 4, 5, 6. A fatigue phenomenon of the material reproducing the working of the latter under the action of rolling loads is thus obtained. Application to testing coatings such as road surfacings. IMAGE
