DIN EN 13863-4:2012-07EN 13863-4:2012 (E) 4 1 Scope This European Standard describes a test method for the determination of the wear resistance to studded tyres of specimens either cut from ha
21、rdened concrete pavements or moulded in laboratory. NOTE The test method is applicable for the finished concrete (end product testing) and not only for the aggregate as described in EN 1097-9. In the report from Swedish Road and Transport Research Institute (1996), Ring Analysis of Nordic Road Simul
22、ators: Proposal for a common test method for the determination of the wear resistance of concrete pavements, more information of the methods precision is given (see Bibliography). Three different configurations of the test equipment are considered in this document, one using truck-wheels and the oth
23、er two using car-wheels. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
