NOTE The expression appropriale to the intended use” means that the selection of the requwements and the perbcular category depends on a number of conditions These conditions *1 mctude traffic density, dimatic conditions, the construction or the course in which the mixture Will be used, and economic considerations
The upper sieve sIze 1) of the agegate in the reclaimed asphalt shall not exceed the upper sieve size 1) of the mixture. The aggregate properties of the reclaimed asphalt shall fulfil the requirements specified for the aggregate for the mixture.
4.5 Additives
The nature and properties of all additives shall be declared and they shall conform to the specifications
requWed in 4.1.
5 Requirements for the mixture
5.1 General
The mix formulation shall be declared and documented.
At the target composition the mixture shall conform to the specified requirements.
When using reclaimed asphalt from mixtures in which a modified bitumen andlor a modifier additive has been used, and/or the mixture itself contains a modified bitumen or a modifier, the amount of reclaimed aspl’iall shall not, unless otherwise agreed between client and manufacturer, for surface courses exceed 10% by mass of the total mixture and for regulating courses, binder courses and base courses exceed 20 % by mass of the total mixture. Any agreement made between client and manufacturer must not be in conflict with national regulatory requirements.
5.2 Composition, grading, binder content and additives
5.2.1 CompositIon
At the target composition the grading and the binder content shall conform to 5.2.2.
At the target composition the additive content shall conform to 5.2.3.
The grading shall be expressed in percentages by mass of total aggregate, using the sieves belonging either to the basic set plus set 1 or the basic set plus set 2 of EN 13043, The binder and additive content shall be expressed in percentages by mass of total mixture. The percentages passing the sieves, with exception of the sieve 0.063 mm shall be expressed to I %, the binder content, the percentage passing sieve 0.063 mm and any additive content shall be expressed to 0.1 %.
5.2.2 GradIng and binder content
The requirements for the grading shall be expressed in terms of maximum and nnimum values for the percentages passing the sieves 1,4 1). 1), 2 mm and 0.063 mm. A combination of sieve sizes from set 1 and set 2 is nol permissible.
In addition the requirements for the grading envelope may include the percentages passing one optional sieve between 0 and 2 mm and one optional fine sieve between 2 mm and 0,063 mm. The target composition of the mixture shall be Within this wading envelope.
0 and the sieves between 0 and 2 mm shall be selected (ron, the following sieves:
— basic sieve set plus set 1:4mm: 5.6 mm; 8 mm: 11.2 mm: 16 mm: 22.4 mm, 31,5 mm, 45mm:
NOTE A reasonable working life within the context of this European Standad is the period of lime dtwing which the performance of the works will be mawilained ala level compatible with the declared performance of the characteristics.
6 Evaluation of conformity
The conformity of Soft Asphalt to the requirements of this European Standard and with the stated values (includlig classes) shall be demonstrated by
— Initial Type Testing in accordance with EN 13108-20;
The method of sample preparation shall be selected from EN 13106-20:2005, 6.5.2. 6.5.3a or 6.5,3b.
— Factory Production Control by manufacturer including product assessment in accordance with EN 13108- 21.
7 Identification
The delivery ticket shall contain at least the following information relating to identification:
— manufacturer and mixing plant:
— mix identification code:
— designation of the mixture.
