Introduction
This Technical Specification is a complementary document to EN 15804 “Sustainability of construction
works – Environmental product declarations – Core rules for the product category of construction
products”.
This document does not replace any of the standard’s requirements and it is not intended to be used as a
stand-alone document.
It is intended to assist the understanding and use of EN 15804 by giving guidance and further explanation
in the preparation of Environmental Product Declarations (EPD) for bituminous mixtures covered by
product standards in EN 13108-series in a common way.
NOTE 1 The title of the clauses in this document follow the EN 15804 to enhance readability.
NOTE 2 The composition of the bituminous mixture is necessary to produce the specific EPD.

1 Scope
This document provides a common European basis with Complementary Product Category Rules (c-PCR)
to EN 15804 for the preparation of Environmental Product Declarations for bituminous mixtures used
on roads, airfields and other trafficked areas covered by relevant product standards in the EN 13108-
series.
Complementary to EN 15804, this document:
— specifies the declared unit;
— defines the system boundaries for bituminous mixtures;
— specifies and describes the default scenarios and rules for defining scenarios for certain life cycle
information modules.
This document applies to the preparation of EPD for the following module configurations:
— cradle to gate with modules C1-C4 and module D. This includes the declaration of the minimum
modules: A1-A3 (product stage), C1-C4 (end-of-life stage) and D (supplementary information beyond
the pavement life cycle);
— cradle to gate with options, modules C1-C4 and module D, only when the added optional modules are
A4 and/or A5. This includes the declaration of the minimum modules (as above), plus A4 (transport)
and/or A5 (construction – installation process).
This document does not cover modules B1-B7.

2) processing of materials from other systems (e.g. crumb rubber, steel and blast furnace slags,
recycled fibres, etc.) for use in bituminous mixtures shall be included in A1 only if they are
allocated as co-products in the previous system. If these are supplied directly into the binder, the
