Product Testing Standards

EN 12697

• 44 Standards covering the testing of

asphalt mixtures

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

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

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.)

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

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.

The Institute of Asphalt Technology

BS 594987 : 2010

• This is the baseline document for all asphalt works.

• Applies principally to Parts 1, 4 and 5 of BS EN

13108 relating to Asphalt Concrete, Hot Rolled

Asphalt (including application of coated chippings to

provide texture for skid resistance) and Stone Mastic

Asphalt,

• Applies from the point of collection from the

production plant until the materials are in-situ and

ready to receive a further superimposed layer or

traffic.

The Institute of Asphalt Technology

Attestation of Conformity

• Initial Type Testing

• Factory Production Control

• Evaluation of Conformity

• CE-marking

The Institute of Asphalt Technology

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).

The Institute of Asphalt Technology

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

The Institute of Asphalt Technology

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.

The Institute of Asphalt Technology

MICRO-DEVAL (MDE)

New to the UK and is similar to

the Los Angeles test but measures

the resistance of an aggregate to

wear.

The Institute of Asphalt Technology

Polished Stone Value (PSV)

This has stayed the same as before.
