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

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Construction Product Regulations• On the 1st July 2013 the CPD was repealed and replaced by the CPR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

➢ EN 13108

• 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

➢ Bmin

➢ Mixture Identification
