15、e CEN/TC 227 “Road materials”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by September 2013 and conflicting national standards shall be withdrawn at the
16、latest by September 2013. 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 be held responsible for identifying any or all such patent rights. This document supersedes EN 13877-2:2004. The following modi
17、fications have been made: The normative references have been reviewed. The definition of continuously reinforced concrete roadbase (CRCR) has been modified to continuously reinforced concrete base (CRCB). The units have been updated from N/mm2to MPa. The limitation for cracks in jointed unreinforced
18、 concrete pavements has been improved. Alternative methods to EN 12390 for splitting strength might be used, if defined by relevant national standards or provisions in the place of use. A note has been included after Table 3 to explain it. Table 3 has been modified to include more splitting strength
19、 classes. In Table 4, a new category of Tolerance, T6, has been included. Alternative methods to CEN/TS 12390-9 for freeze-thaw resistance might be used, if defined by relevant national standards or provisions in the place of use. Regarding quality control, allowance has been included for different
20、number of cores, if defined by specifications in the place of use; and the notes after table 7 have been included as normative text. Reference to EN 197-1 has been added to the Bibliography.
