Abstract

One of the main challenges in road construction and maintenance is ensuring traceability and transparency in managing large quantities of excavated soil and stone. In Slovenia, around 7 million tons of such materials are produced annually. They are often reused on-site or backfilled, yet still treated as waste, without considering their chemical and geotechnical properties or potential value. The new EU Construction Products Regulation (EC 3110/2024) introduces digital product passports to improve transparency and traceability of material properties. Although excavated soil and stone are not clearly defined as construction products under this regulation, applying its principles is increasingly important due to the large volumes involved. This research addresses digital product passport requirements and presents the development of digital material passport platforms for excavated soil and stone within the LIFE IP RESTART project. It explores pathways based on material status, such as waste, by-product, or construction product, supporting more efficient resource use in line with circular economy principles.
