ÖNORM EN 17392-1

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). 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.
