28、hod for preparing the specimens and for removing water from the samples before carrying out the extraction test.The method described in this European Standard needs to be used only to determine the quantity of binder and not to investigate its quality.This European Standard applies to slurry surfaci
29、ng to be used in surface layers for roads, airfields and other trafficked areas.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

32、m the sample by ovendrying or by collection during the solvent extraction process.The soluble binder content of the sample is determined in accordance with EN 126971:2012, Clause 5.Binder content by non-extractive method such as ignition (e.g. according to EN 12697-39) can be used provided a correla
33、tion has been demonstrated.In case of dispute, EN 126971:2012, Clause 5 shall be used.4 Apparatus4.1 Apparatus used for preparation of samples1) Oven, with a suitable capacity and capable of holding the required temperatures.2) Balance having a suitable range capable of weighing a sample to the near
34、est 0,1 g.3) Container, comprising a metal tray or pot.4) End-rounded spatula or metal rod.5) Sampling container.5BS EN 122742:2018EN 122742:2018 (E)4.2 Apparatus used for testingBinder extraction apparatus shall conform to the requirements of EN 126971:2012, Annex B, or alternative methods: EN 1269
35、739 provided a correlation has been demonstrated.There is also provision in EN 12697-1:2012 for the use of the equipment specified in EN 12697-3 or EN 126974 for the case of binder quantity by total recovery.5 Preparation of sample1) The samples of slurry surfacing mixture shall be taken from the sl
36、urry surfacing machine in accordance with EN 122741.2) Transfer the sample from the sampling container to a tray large enough to contain all of the sample when it is broken into small pieces. Break the sample into small pieces of such a size that the water can readily evaporate.NOTE In order to remo
37、ve the entire contents from the sampling container, it is often useful to cut the sides of the container open to regain all the binder.3) Place the broken pieces of the sample in a thin layer on a tray in an oven at a temperature of between 110 and 170 5C, until constant mass. For a temperature of (
38、110 5)C, constant mass is deemed to be achieved when the difference between successive weightings at least at 60 min intervals does not exceed 0,1 % of the mass.4) Mix the broken sample thoroughly and divide it into a test portion with a recommended mass depending on the aggregate size in accordance
39、 with Table 1. If sampling containers with 0,5 l for slurry surfacing mixture with coarse aggregate size 8 mm are used from production, then the entire contents of each container shall be tested without further sample division.Table 1 Recommended mass of test portionMaximum size of aggregatemm2 4 6

41、ll be carried out in accordance with EN 126971:2012, Annex B or EN 1269739.If mixtures containing polymer modified binders are tested, the supplier should indicate the solvent and the extraction procedure should be used to recover the binder from such mixtures.7 Test reportThe test report shall stat
