KPE 2.0
Het KPE 2.0 richtte zich op de achtergrondkennis die nodig is om de RWS-focuspunten Asset Management 2.0 en Duurzame Leefomgeving (KCI) te vervullen. Specifieke gebieden binnen de wegentechniek die moeten worden aangepakt, zijn onder andere het verhoogde gebruik van teruggewonnen asfalt in nieuwe mengsels, het gebruik van alternatieve en bio-based bindmiddelen, levensduurvoorspellingstools voor zowel huidige als toekomstige materialen, verhoogd gebruik van data voor voorspelling, validatie en beoordeling, en tests en modellen om de impact van klimaatverandering op de prestaties van wegverhardingen te beoordelen. Het programma loopt van 2025 tot 2028. De opgedane kennis zal gedurende de looptijd met alle relevante ketenpartners actief gedeeld worden. Hier vind je de presentaties terug van de KPE Dag-2025 en externe workshop.

Multiple Recycling of Porous Asphalt Concrete (PAC) with Hot Mix and Warm Mix Methods
The project investigates the multiple recycling of Porous Asphalt Concrete (PAC) with high percentage Reclaimed Asphalt (RA) using HMA and WMA methods. It aims to develop a comprehensive evaluation framework to support sustainable road construction practices involving multiple recycling. The framework will focus on three key aspects: (1) assessing binder activation and blending effectiveness in RA and their effects on the technical performance of recycled mixtures; (2) evaluating the adequacy of current assessment methods for multiply recycled PAC and RA quality; (3) addressing emissions and their impact on health and safety.
Assessment tool for innovations
To realize the climate ambitions of 2030 and 2050, part of the focus of the pavement engineering community is turning to the wide(r) use of WMA technologies, increase of RA percentages in asphalt mixtures and, mainly, the combination of both, as well as to the use of bio-based materials. Uncertainties arise about the initial quality of this new generation of asphalt mixtures, their behavior/performance, both in the short- and long-term, their ageing susceptibility, durability and expected lifetime, compared to the Hot Mix Asphalt (HMA) materials that are currently used in practice. To address these uncertainties research is initiated under this project.
Data management system
The goal of the topic “KPE data management system” is the development of a well-organized data management system (DAMA) that supports sharing FAIR data mainly within KPE projects. This system provides development, management and an efficient storage strategy that supports the interoperability of data between KPE partners in a common data environment, flexible enough to be called future-proof.
