Sustainability of construction works - Environmental product declarations - Core rules for road materials - Part 1: Bituminous mixtures
This document provides core product category rules for type III environmental declaration of bituminous materials for building and civil engineering according to EN 13108-1, EN 13108-2, EN 13108-3, EN 13108-4, EN 13108-5, EN 13108-6, EN 13108-7, EN 13108-9, and prEN 13108-31. The approach taken for these PCR may be considered applicable and adaptable for other bitumen based products.
This document defines the parameters to be reported, what EPD types (and life cycle stages) to be covered, what rules to be followed in order to generate Life Cycle Inventories (LCI) and conduct Life Cycle Impact Assessment (LCIA) and the data quality to be used in the development of EPDs.
In addition to the common parts of EN 15804, this document for bituminous materials:
- defines the system boundaries;
- defines the modelling and assessment of material-specific characteristics;
- defines allocation procedures for multi-output processes along the production chain;
- includes the rules for calculating the LCI and the LCIA underlying the EPD;
- provides guidance for the determination of the reference service life (RSL);
- gives guidance on the establishment of default scenarios.
Principles used:
- PCR covering bituminous materials;
- from cradle to beyond the building life cycle based on EN 15804;
- polluter pays: processes of waste processing shall be assigned to the product system that generates the waste until the end-of-waste state is reached;
- EPD will be based on declared units (e.g. tonnes of material) and not functional units (e.g. km of road);
- abiotic depletion potential of aggregate should be declared when relevant;
- all use of inert material in the quarry: reclamation, sound and dust protection have to be included in stages A1 to A3 of the EPD;
- data quality will be described (e.g. Average yearly value, average 10 years value, or maximum value ever encountered).
NOTE The Use stage, Informative Module B, depends on the use scenario and this depends on the type of road it is used for, the width of the road, the width of the lane, the total pavement structure and substrate for which the pavement layer it is used, the climate conditions, the maximum and minimum pavement temperatures, the traffic intensity and the number of weights of the axle loadings, etc. The use scenario details are determined by the buyer / user of the bituminous mixture. Therefore, only examples on typical maintenance scenarios are given.
This guideline provides PCRs that can be applied for a particular asphalt mixture, from a specific asphalt plant with a specific production temperature. Hence, the design of the asphalt mixture is necessary to produce the specific EPD.
Nachhaltigkeit von Bauwerken - Umweltproduktdeklarationen - Festlegungen für Straßenbaustoffe - Teil 1: Asphaltmischgut
Dieses Dokument liefert grundlegende Produktkategorieregeln für Typ III Umweltdeklarationen für bitumenhaltige Materialien im Bauwesen nach EN 13108 1, EN 13108 2, EN 13108 3, EN 13108 4, EN 13108 5, EN 13108 6, EN 13108 7, EN 13108 9 und EN 13108 31. Der für diese PCR gewählte Ansatz kann als anwendbar und anpassbar für andere auf Bitumen basierende Produkte betrachtet werden.
Dieses Dokument definiert die anzugebenden Parameter, die abzudeckenden EPD Typen (und Lebens-zyklusphasen), die Regeln, die eingehalten werden müssen, um Sachbilanzen (LCI, en: life cycle inventory) zu erstellen und Wirkungsabschätzungen (LCIA, en: life cycle impact assessment) durchzuführen, und die zu verwendende Datenqualität bei der Entwicklung von EPD.
Zusätzlich zu den gemeinsamen Teilen der EN 15804 liefert dieses Dokument für bitumenhaltige Materialien Folgendes:
— die Definition der Systemgrenzen;
— die Definition von Modellierung und Bewertung materialspezifischer Merkmale;
— die Definition von Allokationsverfahren für Multi-Output-Prozesse entlang der Produktionskette;
— Berechnungsregeln für die der EPD zugrunde liegenden LCI und LCIA;
— eine Anleitung zur Bestimmung der Referenz-Nutzungsdauer (RSL, en: reference service life);
— eine Anleitung zur Festlegung von Standardszenarien.
Angewandte Prinzipien:
— PCR deckt bitumenhaltige Materialien ab;
— von „der Wiege“ über den Lebenszyklus des Gebäudes hinaus, auf der Grundlage von EN 15804;
— Verursacher zahlt: Prozesse zur Abfallbehandlung müssen dem Produktsystem zugeordnet werden, welches den Abfall erzeugt, bis der Status „Abfallende“ (en: end of waste) erreicht ist;
— EPD basieren auf deklarierten Einheiten (z. B. Material in Tonnen) und nicht auf funktionellen Einheiten (z. B Straßenlänge in km);
— abiotisches Abbaupotential von Gesteinskörnung sollte gegebenenfalls deklariert werden;
— gesamte Nutzung von inertem Material im Steinbruch: Rückgewinnung, Schall- und Staubschutz müssen in die EPD Phasen A1 bis A3 aufgenommen werden;
— Beschreibung der Datenqualität (z. B.: durchschnittlicher Jahreswert, durchschnittlicher Wert über einen Zeitraum von 10 Jahren oder der jemals vorgefundene Höchstwert).
ANMERKUNG Die Nutzungsphase, Informationsmodul B, hängt vom Nutzungsszenario ab, welches wiederum ab-hängig ist vom Straßentyp, für das es verwendet wird, von der Straßenbreite, der Fahrspurbreite, der gesamten Struktur und Oberfläche der für den Fahrbahnbelag verwendeten Beschichtung, den Klimabedingungen, den Höchst- und Tiefsttemperaturen des Belags, der Verkehrsdichte, der Anzahl der Gewichte der Achslasten usw. Die Details des Nutzungsszenarios werden vom Käufer/Anwender des Asphaltmischguts bestimmt. Aus diesem Grund werden nur Bei¬spiele für typische Instandhaltungsszenarien gegeben.
Dieser Leitfaden liefert PCR, die auf ein bestimmtes Asphaltmischgut eines spezifischen Asphaltwerks mit einer bestimmten Produktionstemperatur angewandt werden können. Deshalb ist die Auslegung des Asphaltmischguts zur Erstellung der spezifischen EPD notwendig.

Le présent document fournit des règles de définition des catégories de produits destinées aux déclarations environnementales de type III de matériaux bitumineux pour la construction et le génie civil conformément à l’EN 13108 1, l’EN 13108 2, l’EN 13108 3, l’EN 13108 4, l’EN 13108 5, l’EN 13108 6, l’EN 13108 7, l’EN 13108 9, et l’EN 13108 31. La démarche adoptée pour ces RDCP peut être considérée comme applicable et adaptable à d’autres produits à base de bitume.
Le présent document définit les paramètres à consigner, les types de DEP (et phases du cycle de vie) à couvrir, les règles à suivre afin de créer des inventaires du cycle de vie (ICV) et de réaliser des évaluations de l’impact du cycle de vie (EICV) ainsi que la qualité des données à respecter dans le cadre du développement des DEP.
Outre les parties communes de l’EN 15804, le présent document consacré aux matériaux bitumineux :
- définit les frontières du système ;
- définit la modélisation et l’évaluation des caractéristiques spécifiques au matériau ;
- définit les modes opératoires d’allocation pour les processus à multiples extrants le long de la chaîne de production ;
- intègre les règles de calcul de l’ICV et de l’EICV sous-jacents aux DEP ;
- fournit des indications pour la détermination de la durée de vie documentée (DVD) ;
- fournit des indications sur l’établissement de scénarios par défaut.
Principes exploités :
- RDCP couvrant les matériaux bitumineux ;
- du berceau au-delà du cycle de vie de construction sur la base de l’EN 15804 ;
- principe pollueur-payeur : les processus de traitement des déchets doivent être affectés au système de produit générant le déchet jusqu’à ce que l’état de fin du déchet soit atteint ;
- la DEP sera basée sur les unités déclarées (par ex. tonnes de matériau) et non les unités fonctionnelles (par ex. km de route) ;
- il convient que le potentiel d’appauvrissement abiotique des granulats soit déclaré le cas échéant ;
- tout usage de matériaux inertes en carrière : la réhabilitation et la protection contre le bruit et la poussière doivent être incluses dans les phases A1 à A3 de la DEP ;
- la qualité des données sera décrite (par ex. valeur moyenne annuelle, valeur moyenne à 10 ans, ou valeur maximale historique).
NOTE La phase d’utilisation, module informatif B, dépend du scénario d’utilisation et ce dernier dépend du type de route pour lequel il est utilisé, de la largeur de la route, de la largeur de la voie, de la structure totale de la chaussée et du substrat destiné à la couche de chaussée pour laquelle il est utilisé, des conditions climatiques, des températures minimale et maximale de la chaussée, de l’intensité de trafic et du nombre de poids de charge à l’essieu, etc. Les informations sur le scénario d’utilisation sont déterminées par l’acheteur/l’utilisateur du mélange bitumineux. Par conséquent, seuls des exemples de scénarios de maintenance typiques sont donnés ;
Le présent guide fournit des RDCP pouvant être appliquées pour un mélange d’asphalte particulier, issu d’une centrale d’enrobage particulière employant une température de production spécifique. La conception du mélange d’asphalte est ainsi nécessaire pour produire la DEP spécifique.

Introduction
European standard EN 15804 provides Product Category Rules (PCR) for Type III environmental
declarations for any construction product and services.
It provides a structure to ensure that all Environmental Product Declarations (EPD) of construction
products, construction services and construction processes are derived, verified and presented in a
harmonized way.
This document provides additional rules for Environmental Product Declarations (EPD) specifically for
bituminous mixtures. It complements the core product category rules for all construction products and
services as established in EN 15804.
An EPD communicates verifiable, accurate, non-misleading environmental information for products and
their applications, thereby supporting scientifically based, fair choices and stimulating the potential for
market-driven continuous environmental improvement.
The standardization process has taken place in accordance with ISO 14025. All common issues are
covered horizontally for all product types in order to minimize vertical (branch specific) deviations.
All common issues are covered horizontally for all bituminous mixtures in order to minimize intra-
sectoral deviations.
EPD information is expressed in information modules as defined in EN 15804, which allow easy
organization and expression of data packages throughout the life cycle of bituminous mixtures. The
approach requires that the underlying data should be consistent, reproducible and comparable.
In line with EN 15804, the EPD is expressed in a form that allows aggregation (addition) to provide
complete information for construction works. This document does not deal with aggregation at the
construction level nor does this document describe the rules for applying EPD in a construction
assessment.
The document deals with a limited number of quantifiable parameters as predefined in EN 15804.
Future revisions of EN 15804 may lead to the incorporation in this document of additional
predetermined parameters.
NOTE Producers and users of EPDs need to be aware that as each product sector develops its own EPDs,
under their own PCR, then it is generally not possible to compare the outputs of different products or product
types e.g. EPDs for asphalt concrete and surface dressing cannot be directly compared. Comparison between EPDs
can only be realized between mixes that are used in the same application and provide the same performance.

1 Scope
This document provides core product category rules for type III environmental declaration of
bituminous materials for building and civil engineering according to EN 13108-1, EN 13108-2,
EN 13108-3, EN 13108-4, EN 13108-5, EN 13108-6, EN 13108-7, EN 13108-9, and EN 13108-31. The
approach taken for these PCR may be considered applicable and adaptable for other bitumen based
products.
This document defines the parameters to be reported, what EPD types (and life cycle stages) to be
covered, what rules to be followed in order to generate Life Cycle Inventories (LCI) and conduct Life
Cycle Impact Assessment (LCIA) and the data quality to be used in the development of EPDs.
In addition to the common parts of EN 15804, this document for bituminous materials:
— defines the system boundaries;
— defines the modelling and assessment of material-specific characteristics;
— defines allocation procedures for multi-output processes along the production chain;
— includes the rules for calculating the LCI and the LCIA underlying the EPD;
— provides guidance for the determination of the reference service life (RSL);
— gives guidance on the establishment of default scenarios.
Principles used:
— PCR covering bituminous materials;
— from cradle to beyond the building life cycle based on EN 15804;
— polluter pays: processes of waste processing shall be assigned to the product system that generates
the waste until the end-of-waste state is reached;
— EPD will be based on declared units (e.g. tonnes of material) and not functional units (e.g. km of
road);
— abiotic depletion potential of aggregate should be declared when relevant;
— all use of inert material in the quarry: reclamation, sound and dust protection shall be included in
stages A1 to A3 of the EPD;
— data quality will be described (e.g. Average yearly value, average 10 years value, or maximum value
ever encountered).
NOTE The Use stage, Informative Module B, depends on the use scenario and this depends on the type of road
it is used for, the width of the road, the width of the lane, the total pavement structure and substrate for which
pavement layer it is used, the climate conditions, the maximum and minimum pavement temperatures, the traffic
intensity and the number of weights of the axle loadings, etc. The use scenario details are determined by the buyer
/ user of the bituminous mixture. Therefore, only examples on typical maintenance scenarios are given.
This guideline provides PCRs that can be applied for a particular asphalt mixture, from a specific asphalt
plant with a specific production temperature. Hence, the design of the asphalt mixture is necessary to
produce the specific EPD.

5.2 Types of EPD with respect to life cycle stages covered
Figure 1 — Types of EPD with respect to life cycle stages covered and life cycle stages and
modules for the building assessment
5.3 Comparability of EPD of construction products
In addition to the text in EN 15804:
In principle the comparison of products on the basis of their EPD is defined by the contribution they
make to the environmental performance of the construction works. Consequently comparison of the
environmental performance of construction products using the EPD information shall be based on the
product’s use in and its impacts on the construction, and shall consider the complete life cycle (all
information modules).
NOTE 1 EPDs in a construction works context are not tools to compare construction products and construction
services.
NOTE 2 For the sustainability assessment of construction works comparisons of the environmental aspects and
impacts need to be undertaken in conjunction with the social and economic aspects and impacts related to the
construction works.
NOTE 3 For the interpretation of a comparison, benchmarks or reference values are needed. This document
does not set benchmarks or reference values.

---------------------- Page: 11 ----------------------
oSIST prEN 17392-1:2020
prEN 17392-1:2020 (E)
Comparisons are possible at the sub-element level, e.g. for assembled systems, components, products
for one or more life cycle stages. In such cases the principle that the basis for comparison of the
assessment is the entire construction works, shall be maintained by ensuring that:
— the same functional requirements as defined by legislation or in the client’s brief are met;
— the environmental performance and technical performance of any assembled systems, components,
or products excluded are the same;
— the amounts of any material excluded are the same;
— excluded processes or life cycle stages are the same;
— the influence of the product systems on the operational aspects and impacts of the construction
works are taken into account.
The information provided for such comparison shall be transparent to allow the purchaser or user to
understand the limitations of comparability. A justification shall be given for any excluded aspects.
NOTE 4 The difference between two products may be insignificant in the construction works context.
Where an EPD does not cover all life cycle stages relevant for the comparison, e.g. B1 to B7, or if the
assumptions underlying the scenario of a declared information module are not applicable in the
construction works context, then investigations will be required to determine the environmental
aspects and impacts of specific scenarios for the calculation of modules beyond the cradle to gate
modules. These calculations shall be based on scenarios and conditions that are appropriate for the
construction works as the object of assessment.
5.4 Additional environmental information
EN 15804:2012+A2:2019 shall apply.
5.5 Ownership, responsibility and liability for the EPD
EN 15804:2012+A2:2019 shall apply.
5.6 Communication formats
EN 15804:2012+A2:2019 shall apply.

including provision and transport of all materials, products and related energy and water use, as well as
waste processing up to the end-of-waste state or disposal of final residues during this part of the use
stage. These information modules also include all impacts and aspects related to the losses during this
part of the use stage (i.e. production, transport, and waste processing and disposal of the lost products
and materials). Information on typical maintenance scenarios and RSL shall be given.
6.2.5 B6 B7
Not to be applied (not relevant for bituminous products).
6.2.6 C1-C4 end-of-life stage information modules
Information on typical end of life scenarios shall be given.
NOTE Today new pavements are designed to be 100 % recycled / reused in the future. Therefore 100 % of
bituminous products will be recycled in new pavements at the end of their life.
6.2.7 D benefits and loads beyond the product system boundary (module D)
Information on benefits and load scenarios shall be given.
6.3 Calculation rules for the LCA
6.3.1 Functional or declared unit
Refer to EN 15804:2012+A2:2019.
6.3.2 Functional unit
The functional unit can be defined if module B is used. The functional unit shall be able to be calculated
from the declared unit (see EN 15804:2012+A2:2019, 6.3.2.1).
6.3.3 Declared unit
One metric tonne of bituminous mixture.
6.3.4 Reference service life (RSL)
In addition to the text in EN 15804:
Information on RSL shall be given.
The reference service life of the bituminous product shall be consistent with the period of evaluation of
the Civil Engineering Works.
The technical service life of bituminous mixtures is often determined by the practical service life
because of changing the layout of the road infrastructure. The technical service life of bituminous
pavement layers depends on the bearing capacity of the substrate, the conditions of the lower
bituminous layers, the traffic loadings, etc.

In addition to the text in EN 15804:
— Processes in phase A1: Raw Material Supply
Data for all these processes will be based on secondary data, supplier data sources and/or existing
national LCI data. Transportation distances that are part of upstream processes, involving transport of a
raw material through the supply chain before it arrives to the plant, are considered part of the
secondary data. The following impacts are included:
a) Impacts of all co-products of crude oil refining including extraction, transport, refining, and storage.
The co-products of interest to this PCR guidance include gasoline, diesel, residual fuel oil, polymers,
bitumen additives and bituminous binder. The Eurobitume LCI Methodology is used to allocate the
relative impacts of the crude oil refining process across the different co-products.
b) Impacts associated with the extraction and production of burner fuels.
c) Impacts associated with the mining, extraction and production of aggregate.

d) Impacts associated with the use of asphalt additives (including water for foaming).
e) Impacts associated with the processing of site won asphalt to become RA.
f) Transportation of site-won asphalt to the processing plant, is considered to be zero because it is
part of the previous system supplying recycled aggregate into the current system. The system
boundary is considered to be crossed at the site once the reclaimed asphalt enters the processing
plant and impacts after this point (e.g. crushing and sieving) are considered in this system (see
Figure 4).
g) Impacts associated with the production of electricity and transmission to asphalt plant.

— Processes in phase A2: Transport to Asphalt Mixing Plant
Transportation distances of raw materials to the plant are considered to be primary data.
a) Transportation of bituminous binders to the asphalt mixing plant.
b) Transportation of aggregate to the asphalt mixing plant.
c) Transportation of asphalt additives to the asphalt plant.
d) Transportation of the burner fuels to the asphalt mixing plant.
e) Transportation of RA from processing unit to asphalt plant.
