BS EN 13108-3:2016EN 13108-3:2016 (E) 6 Introduction The aim of this European Standard is to enable specificati
27、on of Soft Asphalt mixtures on a performance basis. In 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 giv
28、en. This European Standard covers a large variety of materials for different applications, traffic and climate conditions. EN 13108-3 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
29、been chosen. The tables represent categories that are required 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 ca
30、tegories defined in those documents need to take into account 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 Soft Asphalt and the use of the pavement and to avoid a combin
31、ation of potentially conflicting requirements. BS EN 13108-3:2016EN 13108-3:2016 (E) 7 1 Scope This European Standard specifies requirements for mixtures of the mix group Soft Asphalt for use on low volume roads and roads with low stability. Soft Asphalt is used for surface courses, regulating cours
32、es and bases in colder climates. The mixtures of the mix group Soft 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 selecti
33、on of the constituent materials. It is designed to be 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.
