BS EN 13108-7:2016EN 13108-7:2016 (E) 6 Introduction The aim of this European Standard is to enable specification of Porous Asphalt mixtures on a performance basis. In
29、general, however, there are currently more empirical tests available to describe the mixtures. Depending on the experience with the combination of requirements in this European standard more or less degrees of freedom for the producer may be given. This European Standard covers a large variety of ma
30、terials for different applications, traffic and climate conditions. EN 13108-7 gives properties and listings of possible categories. It has to accommodate the road industry for all of Europe. For this reason the menu approach for properties has been chosen. The tables represent categories that are r
31、equired all over Europe. For this reason numerical values in Tables do not always obey statistical rules. Based on conditions of use specific properties and categories may be defined in documents related to the application of the product. The categories defined in those documents need to take into a
32、ccount the reproducibility of the test when this is given in the appropriate test method. Care should be taken to only select those tests which are relevant to the application of the asphalt and the use of the pavement and to avoid a combination of potentially conflicting requirements. BS EN 13108-7
33、:2016EN 13108-7:2016 (E) 7 1 Scope This European Standard specifies requirements for mixtures of the mix group Porous Asphalt for use on roads, airfields and other trafficked areas. Porous Asphalt is used for surface courses. Porous Asphalt can be laid in more than one layer. The mixtures of the mix
34、 group Porous Asphalt are produced on the basis of hot bitumen. Mixtures utilizing bitumen emulsion and bituminous materials based on in situ recycling are not covered by this standard. This European Standard includes requirements for the selection of the constituent materials. It is designed to be
35、read in conjunction with EN 13108-20 and EN 13108-21. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
