<p>PROBLEM TO BE SOLVED: To provide a rubber friction test method and a rubber friction test device which can easily and precisely evaluate friction abrasion characteristics of rubbers on road surfaces having low frictional coefficient such as wet road surfaces.SOLUTION: In a rubber friction test method, with a state that an outside peripheral surface 11 of a rubber test piece 1 contacted with a cylindrical unit 21 of a rotary drum 2, the rubber test piece 1 and the cylindrical unit 21 of the rotary drum 2 move relatively. A coating containing arabic gum not more than 25% by weight is put on the outside peripheral surface 11 of the rubber test piece 1.</p> |
