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.

Overview

The prEN 17392-1 standard, developed by CEN, establishes core product category rules (PCR) for Type III Environmental Product Declarations (EPDs) specifically tailored to bituminous mixtures used in road construction and civil engineering. This standard complements the general framework provided by EN 15804 by focusing on the life cycle assessment (LCA) and environmental impact reporting of bituminous road materials. It aims to ensure consistency, transparency, and comparability in environmental data for asphalt mixtures, facilitating sustainable construction decisions based on scientifically verified information.

Key Topics

• Scope and Applicability:
  prEN 17392-1 covers bituminous mixtures as defined by various EN 13108 standards (Parts 1 through 9 and 31), including asphalt concrete, soft asphalt, mastic asphalt, porous asphalt, reclaimed asphalt, and others. It is designed for use across roads, airfields, and trafficked surfaces, providing PCR adaptable to other bitumen-based products.

• Environmental Product Declarations (EPDs):
  This document defines parameters for EPD preparation, focusing on the key environmental indicators derived from Life Cycle Inventory (LCI) and Life Cycle Impact Assessment (LCIA). EPDs developed following this standard are based on declared units (e.g., tonnes of material), not functional units, enhancing transparency.

• Life Cycle Assessment (LCA) Methodology:
  Core to the document are instructions to:

  • Define system boundaries from cradle to beyond building life cycle (aligned with EN 15804).
  • Model material-specific behaviors and allocate impacts in multi-output processes.
  • Calculate LCI and LCIA data to underpin the environmental declarations.
  • Incorporate waste management impacts with a polluter-pays principle up to end-of-waste state.

• Reference Service Life (RSL) and Scenario Guidance:
  Guidance is provided for determining RSL of bituminous mixtures, supporting realistic assumptions about in-use performance. Default maintenance and use scenarios are described; however, specifics depend on variables such as road type, traffic intensity, climate, and pavement structure.

• Data Quality and Reporting:
  The standard mandates description of data quality, such as average yearly or 10-year values, ensuring reliable LCA results. It also requires inclusion of abiotic depletion potential for aggregates and considers quarry inert material handling.

• Alignment with Existing Standards:
  prEN 17392-1 builds on EN 15804 and ISO 21930 in the environmental sustainability framework, while harmonizing with product specifications from EN 13108 series for bituminous mixtures.

Applications

The prEN 17392-1 standard is critical for manufacturers, suppliers, and specifiers in the road construction sector who wish to quantify and communicate the environmental impacts of their asphalt products. Key applications include:

• Sustainable Road Design:
  Enabling designers and engineers to integrate verified environmental data when selecting bituminous materials for pavements, promoting greener infrastructure with reduced carbon footprints.

• Product Environmental Transparency:
  Assisting asphalt producers to develop transparent EPDs that support market-driven environmental improvements and compliance with environmental procurement policies.

• Life Cycle Performance Analysis:
  Providing a standardized method to assess environmental impacts from raw material extraction, manufacturing, transport, use, maintenance, and end-of-life processes.

• Regulatory and Market Compliance:
  Facilitating adherence to European construction product sustainability regulations and supporting clients’ decisions in public or private roadworks tenders focused on environmental performance.

European foreword
This document (prEN 17392-1:2020) has been prepared by Technical Committee CEN/TC 227 “Road
materials”, the secretariat of which is held by BSI.
This document is currently submitted to the CEN Enquiry.
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 General aspects
5.1 Objective of the PCR
In addition to the text in EN 15804:
The objective of this document is to provide rules for bituminous materials for use on roads, airfields
and other trafficked areas.
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.
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.

Figure 3 — Diagram of the system boundaries, processes, and data types
6.3.5.2 Product stage
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.

Figure 4 — Reclaimed Asphalt processing model with elementary flows
— Processes in phase A2: Transport to Asphalt Mixing Plant
Transportation distances of raw materials to the plant are considered to be primary data.

criteria.
6.3.5.4 Use stage
6.3.5.4.1 General
EN 15804:2012+A2:2019 shall apply.
6.3.5.4.2 B1-B5 Use stage information modules
— B1 Use of the installed product in terms of any emissions to the environment (not covered by B2-
B7)
Release of substances from the asphalt pavement to soil or ground water:
The EPD does not need to give this information because the horizontal standards on measurement of
release of regulated dangerous substances from construction products using harmonized test methods
according to the provisions of the respective technical committees for European product standards are
not available yet.
— B2 Maintenance
The module “Maintenance” covers the combination of all planned technical and associated
administrative actions during the service life to maintain the product installed in construction works or
its parts in a state in which it can perform its required functional and technical performance, as well as
preserve the aesthetic qualities of the product.
These minor maintenance activities will include preventative and regular maintenance activity such as
filling cracks, sealing of cracks, minor (pothole) patching and replacement of damaged or degraded
parts (mill and fill).
Next to these minor maintenance activities there are also “major maintenance techniques”, which apply
to the whole surface of the pavement. The mostly used major maintenance techniques are surface
treatment, non-structural asphalt overlay and structural asphalt overlay.
The boundary of “maintenance” shall include in addition:
— the production and transportation of any component and ancillary products used for maintenance,
including cleaning;
— transportation of any waste from maintenance processes or from maintenance related
transportation;
— the end-of-life processes of any waste from transportation and the maintenance process, including
any part of the component and ancillary materials removed.
— B3 repair
Not to be applied. An asphalt layer can be “repaired” by replacing a damaged part. This is covered under
maintenance.
— B4 Replacement
An asphalt top layer or a part of the upper layers or a whole asphalt pavement can be replaced.
The boundary for “replacement” shall include:
— the production of the bituminous mixture used for replacement;
— replacement process, including related water and energy use and the production aspects and
impacts of any waste of materials used during the replacement process;
— the transportation of the bituminous mixture and equipment used for cleaning and replacement;
— the end-of-life processes of the removed bituminous mixture.

Processes in phase C1: Deconstruction of the asphalt pavement layer or asphalt pavement. This
deconstruction can result in asphalt slabs or milled granulated asphalt.
Processes in phase C2: Transportation of the bituminous pavement material as part of the waste
processing, e.g. to a recycling site and transportation of waste e.g. to final disposal;
Processes in phase C3: Reclaimed asphalt processing will take place in phase A1:5 as waste processing
is part of the product system under study. The reclaimed asphalt will be crushed and / or sieved into
size fractions for further reuse or recycling.
6.3.6 Criteria for the exclusion of inputs and outputs
In addition to the text in EN 15804:
a) Upstream impacts of extraction, production, and manufacturing of any material that is not
consumed in the production of the asphalt mixture is considered to be part of the plant
infrastructure and therefore may be excluded from the system boundary.
For example:
1) The asphalt mixture production equipment and machinery and its upkeep and maintenance,
including dust filters, loader tyres, lubricants and any other substance used to facilitate the
smooth functioning of the plant;
2) Machinery for the recycling of site-won asphalt;
3) Solar panels or any other alternative energy apparatus that is used to substitute traditional
energy sources at the plant;
4) General management, office, and headquarter operations;
5) Personnel at the plant or their commuting to and from the plant.
b) In case of insufficient input data or data gaps for a unit process, the cut-off criteria shall be 1 % of
the total (renewable and non-renewable) primary energy usage and 1 % of the total mass input of
that unit process. The total sum of neglected input flows shall not exceed 5 % of energy usage and
mass. This applies particularly to material and energy flows known to have the potential to cause
significant emissions into air and water or soil during the life cycle of the product; it also applies to
processes that are known to be resource intensive.
c) Materials that are less than 1 % of the total mass input but are considered environmentally relevant
include additives and polymers such as those listed below. There are data gaps in their publicly
available life cycle inventories and these materials should be included when publicly available data
exists. This may include, but not limited to, the following:
1) Polymers in binder, broken down into two classes of chemicals: elastomers or rubbers, such as
styrene-butadiene-styrene (SBS), and plastomers.
2) Liquid antistrips, recycling agents, and warm-mix chemical additives.
3) Fibres.
d) Recycled material
All inputs and outputs to a (unit) process shall be included in the calculation, for which data are
available. Data gaps may be filled by conservative assumptions with average or generic data. Any
assumptions for such choices shall be documented. Particular care should be taken to include material
and energy flows known to have the potential to cause significant emissions into air and water or soil
related to the environmental indicators of this standard. Conservative assumptions in combination with
plausibility considerations and expert judgement can be used to demonstrate compliance with these
criteria.
6.3.7 Selection of data
In addition to the text in EN 15804:
An EPD describing an average product shall be calculated using representative average data of the
products declared by the EPD (preferred solution).
An EPD describing a specific product shall be calculated using specific data for at least the processes the
producer of the specific product has influence over. Generic data may be used for the processes the
producer cannot influence e.g. processes dealing with the production of input commodities, e.g. raw
material extraction or electricity generation, often referred to as upstream data (see Table 1)
(alternative solution).
NOTE It is essential to have data which meet EPD objectives, at the stated level (e.g. national, European level)
especially for the following:

When data from EPDs are used for upstream and downstream processes, the use of an
EN 15804 compliant format for an EPD is preferable.
When available, energy mixes used for EPD are those provided by the suppliers. If not available,
reference databases shall be used.
Data assumption for average EPDs can be defined at national level following principles available in
the place of production and use.
6.3.8 Data quality requirements
The quality of the data used to calculate an EPD shall be addressed in the project report (see Clause 8
and EN ISO 14044:2006, 4.2.3.6). In addition the following specific requirements apply:
a) Age — Data considered, collected and used should be no more than 5 years old, unless it is
unchanged and verified by third party.
b) Representativeness — Data should represent the technology in use.
c) Geography — Data should represent the proper geographical region.
d) Local data when available, and then regional or national data should be used.
e) Alternative data sources modified with the local energy mix may be used.
f) Precision — Data shall be reported to no more than two significant figures.
g) Units —metric units have to be used.
h) Completeness — Shall include all data within the defined system boundaries as noted in this
document.
i) Uncertainty — Shall evaluate any assumptions and primary data through sensitivity analysis as
noted in this standard.
Data sources should be publicly available and freely accessible to ensure transparency. Use of
transparent data source will ensure comparability among EPDs developed using this document by
limiting any variability due to differences in the upstream data within the system boundaries.
