This European Standard shall be given the status of a national standard, either by publication of a
13、n identical text or by endorsement, at the latest by October 2012, and conflicting national standards shall be withdrawn at the latest by October 2012. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not b
14、e held responsible for identifying any or all such patent rights. This document supersedes EN 13863-4:2004. In comparison with the previous version of the Standard published in 2004, the configuration of the test equipment is now more precisely described. This European Standard is one of a series co
15、ncerned with test methods for the functional requirements for concrete pavements: EN 13863-1, Concrete pavements Part 1: Test method for the determination of the thickness of a concrete pavement by survey method; EN 13863-2, Concrete pavements Part 2: Test method for the determination of the bond be

According to the CEN/CE
17、NELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithua

BS EN 13863-4:2012EN 13863-4:2012 (E) 4 1 Scope This European Standard describes a test method for the determination of the wear resistance to studde
19、d tyres of specimens either cut from hardened 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 (19
20、96), Ring Analysis of Nordic Road Simulators: 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 docum
21、ent, one using truck-wheels and the other 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.
