Important Differences
• ENs relate to the product.. “in the back
of the lorry”
• Target & Tolerance concept
• Some description changes

The Institute of Asphalt Technology
Important Differences (cont.)
• Mixture are evaluated for product conformity
against the “selected” properties within the
EN Spec.
• Product conformity (attestation of conformity)
is evidenced by CE marking
![Page 11: The Institute of Asphalt Technology CE Marking of ...ab4.beri.ulster.ac.uk/ceni/e107_files/public/reza_shah...The Institute of Asphalt Technology EN 13108 Standards - Products •EN](https://reader030.vdocuments.mx/reader030/viewer/2022021419/5a9ee15b7f8b9a67178c0234/html5/thumbnails/11.jpg)
The Institute of Asphalt Technology
Important Differences (cont.)
• The specification tolerances for grading and
binder content are NOT included in the
individual product standard- They sit within
EN 13108-21 (PD 6691)
• Binder and filler content are NOT adjusted to
compensate for sampling bias
![Page 12: The Institute of Asphalt Technology CE Marking of ...ab4.beri.ulster.ac.uk/ceni/e107_files/public/reza_shah...The Institute of Asphalt Technology EN 13108 Standards - Products •EN](https://reader030.vdocuments.mx/reader030/viewer/2022021419/5a9ee15b7f8b9a67178c0234/html5/thumbnails/12.jpg)
The Institute of Asphalt Technology
Type Testing (New Terminology)
• EN 13108 Applies two approaches:
• Empirical Approach
• Specifies Material Based on:
• Composition alone or
• Composition & Performance related tests
– (performance related – testes which indirectly
measure performance (i.e. Void content etc.)
![Page 13: The Institute of Asphalt Technology CE Marking of ...ab4.beri.ulster.ac.uk/ceni/e107_files/public/reza_shah...The Institute of Asphalt Technology EN 13108 Standards - Products •EN](https://reader030.vdocuments.mx/reader030/viewer/2022021419/5a9ee15b7f8b9a67178c0234/html5/thumbnails/13.jpg)
The Institute of Asphalt Technology
Type Testing – Cont.
• Fundamental Approach
• Specifies Material Based on:
• Performance Based tests, with limited
requirements for composition
– (performance based – testes which
directly measure performance (i.e.
Stiffness, deformation resistance &
fatigue etc.)

The Institute of Asphalt Technology
CE Marking Approval process
• Select target grading and binder content from the tables in
the Annex in PD 6691
• Carry out Type Testing according to EN 13108-20 to prove
target mix conformity
• Apply Factory Production Control (FPC) tolerances to the
target composition to formulate the compliances
specification.
• Follow the FPC requirement to manufacture the product
• Certify the system (by approved certifying body) to be able
to CE mark the product
![Page 23: The Institute of Asphalt Technology CE Marking of ...ab4.beri.ulster.ac.uk/ceni/e107_files/public/reza_shah...The Institute of Asphalt Technology EN 13108 Standards - Products •EN](https://reader030.vdocuments.mx/reader030/viewer/2022021419/5a9ee15b7f8b9a67178c0234/html5/thumbnails/23.jpg)
The Institute of Asphalt Technology
Example for determination of target
grading and it’s limits
• Determine the average grading for the
mixture over last 6 to 12 months and this
should be within grading envelop given
in PD 6691.

Attestation of Conformity
• To obtain CE mark there is a Procedure of Attestation
of Conformity For asphalt
1. Initial type testing – by the manufacturer.
2. Factory production control - by the manufacturer.
3. Initial inspection plus a continuous surveillance of the FPC
by a notified body (a neutral third party).

CE-marking
• In CPD the use of CE marking is described
• A product for construction works and placed on the
European internal market must have a CE marking.
• CE marking on a product indicates that the product
satisfies all the provisions of the CPD, including the
conformity assessment procedures.
• Asphalt mix produced according to the harmonised
European standards, must carry the so called CE
marking

Aggregate Test - Flakiness (FI35)
Flakiness test has changed you now
use a bar sieve along with the new
sieve sizes.
Results are lower then the old method

Aggregate Test – Los Angeles (LA30)
• Is new to the UK, it measures the
fragmentation / strength
• Replace the old 10% Fines value
• The lower the number the harder the stone
• LA of 30 or less will be within
specification.

MICRO-DEVAL (MDE)
New to the UK and is similar to
the Los Angeles test but measures
the resistance of an aggregate to
wear.
