ABSTRACT:
The present invention relates to an abrasion tester, and in particular to an abrasion tester capable of testing abrasion or breakage of a road generated by the travel of cars in the winter or summer under actual road conditions. The tester includes a turntable rotatably supported in the apparatus for receiving test pieces, a cooling or high temperature chamber confronting the turntable so as to subject the test pieces to high or low temperatures, and a rotatable grinding member movable into and out of contact with the test pieces. Thus, when the grinding member is brought into contact with a test piece and is rotated, the turntable rotates to simulate travel of the grinding member on the test piece. Further, rotation of the turntable moves the test pieces through the chamber where they are subjected to appointed temperature conditions.
