3 Terms and definitions

For the purposes of this document, the following terms and definitions apply

composition of a single mixture expressed as a target composition

Note 1 to entry: A target composition can be expressed in two ways; see 3.3 and 3.4

3.3

input target composition

expression of a mix formulation in terms of the constituent materials, the target grading curve and the percentage of binder added to the mixture

Note 1 to entry: This will usually be the result of a laboratory mix design and validation

Note 2 to entry: The target binder content is defined in the relevant product standards

3.4

output target composition

expression of a mix formulation in terms of the constituent materials and the target mid point grading and soluble binder content to be found on analysis

Note 1 to entry: This will usually be the result of a production validation

Note 2 to entry: The target binder content is defined in the relevant product standards

Type Testing is the terminology adopted in this Standard for the Determination of Product Type

For each mix formulation the Type Testing procedure shall be carried out to provide proof that the formulation meets relevant requirements in the product standard

NOTE 1 The European Standards for bituminous mixtures each contain a number of requirements for composition, physical and mechanical properties Some of these are expressed as direct measurements of mechanical properties such as stiffness or deformation resistance, while others, such as binder content or air voids content, are proxy measurements for other properties

Determination of Product Type shall be performed to show conformity with the product standard on first use for bituminous mixtures being put onto the market

The results of the Type Testing shall be presented in a Type Test report containing all of the information required by this European Standard and the relevant Product Standard

Where the family approach is adopted, its use shall be restricted to correlation between mix formulations with similar volumetrics and identical composition other than for binder grade

For example, Asphalt Concrete with a 70/100 bitumen might fulfil specific requirements for resistance

to deformation Changing only the binder to a harder grade, such as 40/60, will not adversely affect this property Additional testing for that property in that case is not necessary to claim the same performance category, but if an improved category is declared, additional testing is required

NOTE 2 It can also be assumed that a change only in binder grade will not affect the permeability of Porous Asphalt

4.2 Validity

4.2.1 Period of validity

A Type Test Report is valid for a single mix formulation until there are changes in constituent materials,

as described in 4.2.2 to 4.2.5 or in their properties which influence the mix formulation, characteristics and/or performance (when the subsequent performance is reduced in comparison to that originally declared) In those circumstances, it will be necessary to generate a new or revised Type Test Report as appropriate to the revised target composition and/or performance

NOTE Changes in constituent materials might also result in enhanced mixture performance to that originally declared Producers can determine if and when they declare such enhancements, or retain the original declaration

of performance e.g when using the family approach These changes can be defined in documents related to the application of the product

Mix formulations without changes to declared performance, as above, shall be re-validated at least every 5 years

4.2.2 Changes in aggregate

A new Type Test shall be required under the following circumstances:

a) if there is a change in the coarse aggregate or all-in aggregate constituting:

1) change in the category of coarse aggregate or all-in aggregate, as defined in EN 13043, for one

of the following properties: shape, percentage of crushed and broken surfaces, resistance to fragmentation, resistance to wear, resistance to abrasion by studded tyres (where appropriate); or

2) change in rock type as defined by EN 932-3; or

3) change in particle density (weighted mean of a combination of coarse aggregates) greater than 0,05 Mg/m3; (more than ± 0,05 Mg/m3)

b) if there is a change in the origin, or, where appropriate, the angularity category of fine aggregate;

NOTE Origin might be defined in documents related to the application of the product

c) if there is a change in the origin of added filler

4.2.3 Change in bitumen

A change in bitumen grade or type (e.g from paving grade to polymer modified bitumen) shall result in

a new Type Test for relevant Characteristics, except where a family approach is being used (see 4.1, last paragraph and NOTE 2)

4.2.4 Change in Reclaimed Asphalt

A new Type Test Report shall be required if changes in the properties of the reclaimed asphalt (as described in the relevant parts of EN 13108-8:2016, Clauses 4 and 5) result in a change to the performance levels or classes of the mix formulation as declared in the Type Test Report and as required in 4.2.1

This may be the result of variations in reclaimed asphalt feedstocks to those initially considered

4.2.5 Change in additive

A new Type Test shall be required if the type or properties of the additive change to an extent that the performance levels or classes of the mix formulation will change from those declared in the Type Test Report

Samples of constituent materials used in Type Testing shall be, or have been, assessed for conformity as defined in Table A.1

For properties of constituents, tests carried out as part of their AVCP procedures used to demonstrate conformity of the aggregates, bitumens, etc with the appropriate European Standard shall be acceptable

6 Bituminous Mixtures

6.1 General

Type Testing includes all tests on the bituminous mixture to determine the performance levels or classes required by the appropriate product standard, for which a declaration of performance is being made The requirements are detailed in Clauses B.1 to B.8

NOTE 1 The approach in this Type Testing European Standard is based on the ”menu” principle and allows bituminous mixes to be validated in a number of different ways Choices need to be made concerning specimen preparation and test conditions These will be appropriate to the requirements selected for the intended purpose, where known or defined in documents related to the application of the product

NOTE 2 Where the relevant EN 12697 test method requires the testing of multiple test specimens to produce a single result the tables in Annex B refer to this whole procedure as a single test

6.2 Application

The Type Testing of bituminous mixture properties shall comply with one of the three models a), b) or c) below:

a) all properties demonstrated by laboratory validation;

b) all properties demonstrated by production validation;

c) some properties demonstrated by laboratory validation, some properties demonstrated by production validation

NOTE Tests for the same property made on laboratory prepared and compacted specimens will often give results which are different from those on plant mixed and site compacted specimens

6.3 Sampling and testing

All testing shall be carried out in accordance with the appropriate European test method, as stated in Annex C and Annex D, on samples taken in accordance with the appropriate EN sampling method to be representative of the normal constituents and mixed materials

Some test methods have limitations on the aggregate size of material which can be tested This can affect both testing and specimen preparation Such limitations should be appreciated by those considering their use

For mixtures with reduced mixing- and laying-temperatures different temperatures for specimen preparation than those specified in EN 12697-35 may be defined in documents related to the application of the product

6.5.3 Production validation

When executing production validation, the bituminous mixture shall be produced in a full-scale asphalt plant under standard operating conditions set to produce the declared mix formulation Test specimens

of the bituminous mixture shall be prepared using one of the following procedures:

a) Representative sample of the bituminous mixture shall be taken and test specimens shall be compacted in the laboratory in accordance with one of the methods and compaction levels specified from Annex C as detailed in the product standard

b) Mixed material shall be laid in a full-scale trial pavement using full scale paving equipment and procedures (see Table C.1, C.1.21 and C.1.26 for compaction) Representative test specimens shall then be cut from the pavement by sawing or coring

When using production validation, the Type Testing procedure shall include tests on the specimens used in validation of mix properties to confirm that the soluble binder content and grading are within

the close tolerance limits for the output composition, given in EN 13108-21:2016, Annex A, Table A.2 (mean of four samples)

7 Type Test Report

7.1 General

The Type Test report shall include the information required by the Product Standard and as listed in 7.1

to 7.5 and shall be accompanied by all appropriate technical documentation and shall be kept for at least 10 years after the product has been first placed on the market
