22、ive Annex ZA, which is an integral part of this document. The main technical changes brought to EN 13808 are as follows: introduction of additional characteristics and revision of performance classes for cationic bituminous emulsions (Table 2); consideration of the characteristics of the residual bi
23、nder by distillation (Tables 3 and 4); possibility to assess durability on either a stabilised binder (stage 1 of durability) or on a stabilised and PAV aged binder (stage 2 of durability) or on both types of binders (Tables 3 and 4); rewriting of Clause 6 (Assessment and Verification of the Constan
24、cy of Performance - AVCP) and Annex ZA in accordance with the requirements of Regulation (EU) 305/2011 (Construction Products Regulation-CPR); incorporation of the clauses on AVCP previously covered by EN 14733:2005+A1:2010. This standard is part of a family of European Standards for bitumens as fol

DV for “Declared Value“: this class shall mean tha
26、t the manufacturer is required to provide a value or value range with the product. 5 Requirements and test methods 5.1 General This European Standard is a framework of specifications and classes for properties of cationic bituminous emulsions which are chosen from Table 2, Table 3 and Table 4. NOTE
27、1 The list of properties has been set up considering the existing regulations. BS EN 13808:2013EN 13808:2013 (E) 9 The properties in Table 2 characterise the emulsion. Table 3 and Table 4 define the properties and performance classes applicable to the residual binders obtained after distillation, re
28、covery, stabilisation and ageing procedures. In specifying an emulsion, the appropriate class for each technical requirement shall be selected in turn from the classes given in Table 2, Table 3 and Table 4. When tested by the methods given in a table, the various grades shall conform to the limits s
29、pecified in that table. The selection of classes for all requirements shall be made to avoid unworkable combinations. NOTE 2 Tables 2 to 4 apply to emulsions specified in all countries. Each country will then have a particular selection of specifications, which are covered in Tables 2, 3 and 4. It i
30、s useful for each country to publish in a national guidance document for each application, their requirements from the tables. The appropriate class for each technical requirement of application is selected in turn and the selection of classes will be made on a regional basis, in order to avoid unwo
31、rkable combinations. An example of a typical specification for a C 69 BP 2 emulsion is presented in Annex B. 5.2 Properties of the emulsion (Table 2) 5.2.1 Binder content Binder content shall be determined by water content according to the procedure specified in EN 1428 or as the sum of the residual
32、 bituminous binder and oil distillate obtained according to the procedure specified in EN 1431. Alternatives methods can be used if a correlation to these methods can be proven. In case of dispute, EN 1428 or EN 1431 shall be used. 5.2.2 Breaking behaviour There are three possible methods for determ
33、ining the breaking behaviour. It is compulsory to declare a performance class according to one of these methods. NOTE EN 13075-1 could be used for fast and medium curing emulsions. EN 13075-2 or EN 12848 could be used for slow setting and over-stabilised emulsions. 5.2.3 Residue on sieving 0,5 mm si
34、eve The procedure specified in EN 1429 shall be used. 5.2.4 Viscosity Efflux time according to the procedure specified in EN 12846-1 or dynamic viscosity according to the procedure specified in EN 13302 shall be used to characterise the behaviour of the emulsion after spraying (surface dressing or t
35、ack coat applications) or during mixing with aggregates (coating applications). 5.2.5 Water effect on binder adhesion Adhesivity shall be checked with one or several reference aggregates according to the procedure specified in EN 13614. When declaring performance, the nature of the reference aggrega
36、te which has been used shall be indicated. 5.2.6 Penetration power Penetration power characterises the ability of an emulsion to penetrate a substrate. The procedure specified in EN 12849 shall be used. 5.2.7 Oil distillate content The oil distillate content shall be determined according to the proc
37、edure specified in EN 1431. 5.2.8 Residue on sieving 0,16 mm sieve The procedure specified in EN 1429 shall be used. BS EN 13808:2013EN 13808:2013 (E) 10 5.2.9 Efflux time at 85 C Efflux time at 85 C according to the procedure specified in EN 16345 shall be used to characterise viscosity at a temper
38、ature close to possible spraying conditions. It applies only to spraying applications. NOTE The method specified in EN 16345 is only suitable for viscous, high bitumen ( 65 %) content emulsions. 5.2.10 Storage stability by sieving The procedure specified in EN 1429 shall be used. It characterises th
39、e ability of a bituminous emulsion not to form coarse particles ( 0,5 mm) within 7 d of storage. 5.2.11 Settling tendency The procedure specified in EN 12847 shall be used. It characterises the difference in water content of the top layer and the bottom layer of a prescribed volume of sample after 7
40、 days of storage. NOTE Storage stability is a different concept than settling tendency. Although both phenomena are often linked, an emulsion may settle without modification of particle size distribution (no coalescence of emulsion droplets). 5.3 Residual, recovered, stabilised and aged binders from
41、 cationic bituminous emulsions (Table 3) 5.3.1 Residual binder by distillation Residual binder by distillation refers to the binder obtained as a result of the distillation procedure specified in EN 1431 (residual binder after extraction of water and oil distillate). 5.3.2 Recovered binder Recovered
42、 binder refers to the binder obtained according to the procedure specified in EN 13074-1. The recovered binder is deemed to represent the binder obtained immediately after the breaking of the emulsion (coalescence of the binder and elimination of the water). The recovered binder can be replaced by t
43、he bituminous phase of the emulsion, i.e. the bituminous binder and added flux, which has been used to manufacture the emulsion. In the event of dispute, the recovered binder shall be used. When declaring performance for the recovered binder, the type of binder which has been used shall be indicated
44、. 5.3.3 Binders to be considered for the assessment of durability 5.3.3.1 Stabilised binder Stabilised binder refers to the binder obtained according to the procedure specified in EN 13074-1 followed by EN 13074-2. 5.3.3.2 Aged binder Aged binder refers to the binder obtained according to the proced
45、ure specified in EN 13074-1 followed by EN 13074-2 and EN 14769 (65 h at 85 C).The binder to be used for the ageing procedure according to EN 14769 can be replaced by the residual binder by distillation obtained according to the procedure specified in EN 1431. In the event of dispute, the tests on t
46、he binder obtained according to the procedure specified in EN 13074-1 followed by EN 13074-2 and EN 14769 shall be used. When declaring performance for the aged binder, the type of binder used for the EN 14769 ageing procedure shall be indicated. 5.4 Properties of residual, recovered, stabilised and
47、 aged binders from cationic bituminous emulsions (Table 4) 5.4.1 Consistency at intermediate service temperature Consistency at intermediate service temperature shall be assessed according to the procedure specified in EN 1426 (needle penetration). The temperature for the test is dependent on the co
48、nsistency of the binder. The BS EN 13808:2013EN 13808:2013 (E) 11 penetration test shall be performed at 25 C when the binder has a penetration smaller than or equal to (330 x 0,1) mm. If the penetration at 25 C is greater than (330 x 0,1) mm, the test shall be performed at 15 C. 5.4.2 Consistency a
49、t elevated service temperature The test method is dependent on the consistency of the binder. If penetration at 25 C is smaller than or equal to (330 x 0,1) mm, consistency at elevated temperature shall be assessed according to the procedure specified in EN 1427 (softening point). If penetration at 25 C is greater than (330 x 0,1) mm, consistency at elevated service temperature shall be assessed either by dynamic viscosity at 60 C (procedure specified in EN 12596 or EN 13302) or kinematic viscosity at 60 C (procedure specified in EN 12595). 5.4.
