HARMONIZED EUROPEAN TEST METHODS

摘要

In the general move towards harmonised standards across Europe to reduce potential barriers to trade, a Comite Europeen de Normalisation (CEN) task group was set up in 1990 to develop a set of test methods for asphalt mixtures. Work has been underway since then and some methods have become European standards. At the same time, a set of asphalt specifications for the material as delivered to site was being developed by another CEN task group. These specifications, together with the associated test methods, are due to be completed for implementation at the end of 2003. Although the test methods required to support the specifications have taken precedence, further tests on the properties of the in-situ material are also being developed, but without the same urgency. This paper (by the original and current convenors of the test method task group) reviews the 43 test methods that the task group is currently responsible for in terms of their history and contents. Once implemented, these tests will replace all equivalent standards across Europe.
