Construction Products Directive• European Commission White Paper under the Single European
Act 1986 as one of 279 legislative measures needed to complete the Internal Market.
• The principle aim of the Directive was to remove technical barriers to trade on construction products
• European Standardisation Bodies such as CEN and CENELEC were mandated by the Commission to produce the essential requirements in the form of Harmonised Standards.
• Commission Level to Industry level by the use of Technical Committees and Working Groups.
NSAI Standards Development Division

➢ Once an EN is published, Ireland (NSAI) are obliged to adopt the EN as a National Standard
➢ NSAI is a Member of CEN – European Committee for Standardisation
➢ CEN Technical Committee 227 develop European Standards (EN’s) on Road Materials
➢ Irelands participation in CEN work is vital to ensure Irish requirements are included in the EN’s.
➢ Government Agency – promoting the development, use and compliance with National, European and International Standards and European Directives

and replacing BS 4987 and BS 594
Construction Products Directive
• The directive also set out systems for the
Attestation of Conformity, and
• Conformity with the directive was to be
evidenced by affixing the CE Mark and
therefore their access to the market shall not be
hindered.
• EN13108 introduced a menu approach to material Composition,
• a whole new process and language around the production of construction materials such as;
• Initial Type Testing
• Evaluation of Conformity
• Attestation of Conformity
• CE Marking
Hence SR 28 / 2009 was produced
Its purpose to provide guidance on the use of EN13108 in Ireland
• CE Marking was considered to be OPTIONAL
Construction Product Regulations• On the 1st July 2013 the CPD was repealed and replaced by the CPR
• As a European Regulation was automatically transposed into EU and National Law and its implementation is mandatory.
• The general objectives and main instruments of the Construction Products Directive (CPD) did not change in the CPR. i.e.
• To overcome the technical barriers to trade
• The same testing and labelling approaches for the same construction products.
• The CPR is intended to clarify, simplify and improve the credibility of the system.
• The CPR continues to use the instruments developed for the CPD.
• Introduces stricter and more transparent procedures and amends some of the terminology in order to be more precise.
Construction Product Regulations -Benefits
The benefits of CPR for stakeholders are:
• free circulation of construction products in the EU’s Single Market
• products have to be tested only once according to a harmonised
European standard
• national authorities can set performance requirements using the
harmonised European standard
• users of construction products can better define their performance
demands
• market surveillance can rely on one common information structure.

A N other Specification
SR 28 - 2018
IS EN 13108
• TII Specification Series 900
was the only specification
available for Bituminous
Products
• Guidance was required on the
other uses of the various
products in the market place.
• SR 28 provides a methodology
for Specifications for other
uses.

An Introduction To The New SR 28
“Guidance on the use and specification of bituminous materials in Ireland”
• What is SR28 and Why is it needed?
• Our approach
• SR28 – The Detail
• Tables
• Annexes & Advice
➢ Overview
➢ What is SR 28?
‘Recommendation for the use and implementation of the I.S. EN 13108 series bituminous mixtures – material specifications’
➢ What is SR 28?
I.S. EN 13108
Part 1 –Asphalt
Concrete
Part 4 -HRA
Part 5 -SMA
Part 6 -Mastic
Part 7 -Porous
Part 8 -RAP
Part 20 & 21 – Type
Test & FPC
• Start from scratch rather than update existing SR28
• Knowledge gaps
• Over specification -Tii 900 series
• One stop shop!
• Aimed at specifiers Architects, Engineers…
• Transport, Laying, Compaction outside scope to be covered in I.S.844
• SR28 highlights end use applications and material selection
➢ SR28 – Before work Started
• Body of the document
• Introduction
• Requirements
• Constituents
• Binder content Bmin
• Identification
• Type Testing
• Factory Production Control
• The Annexes & Tables
➢ Layout of SR28
• Binder content but not as we’ve known it
• What’s heavier a tonne of polystyrene or a tonne of aggregate?
• Lower density = more binder
• Higher density = less binder
➢ Bmin
The Annexes• Annex A - End use applications for mixture
• Annex B - Mix Design Parameters
• Annex C - Composition , grading, binder content etc.
• Annex D - Over Specification-Conflicting Requirements
• Annex E – Guidance for determining mixtures for particular end uses
• Annex F - Coated chippings for application to hot rolled asphalt surface courses
• Annex G - Protocol for determining the design binder content of designed HRA
surface course mixtures to I.S. EN 13108-4
• Annex H - Protocol for determining the design content of designed Marshall
mixtures
• Annex I - Examples of Declaration of Performance and CE Marking
• Annex J - Test Methods

c The optimum binder content, expressed as B, is required to be established for HRA mixtures through a design procedure in accordance with Annex G.
d The binder content for AC and SMA mixtures, expressed as Bmin, in this table, is corrected for FPC purposes to B, in accordance with Clause 5.3.2
➢ From Annex A we’ve chosen s suitable material
➢ From Annex B We’ve chosen suitable properties
for that material
➢ From Annex C we’ve got a grading envelope to
chose targets
➢Binder content
What we got from Annex C
• Selected a suitable material in Annex A
• Selected suitable properties in Annex B – Voids, water sensitivity, Wheel Tracking
• Selected the composition of the mix in Annex C
• These steps are repeated for binder and surface course
Summarising Those Steps
• Conflicting requirements
• All in the SR is not conflicting and conforms to Annex D
• Ensures users don’t over-specify
