In December 2015, the EU Commission adopted a Circular Economy Action Plan with the aim to set the European Union “on the course of the transition towards a more sustainable model for economic development”. The action plan looks at the whole lifecycle of products and adopts a systemic approach that promotes partnerships along the entire value chain and across five priority sectors, among which is the “Construction and Demolition” sector.
In March 2019 the Commission published a Staff Working Document on the implementation of the Circular Economy Action Plan with 54 actions, with several actions affecting the way we will build and maintain the roads in the coming years. Among others, it can be highlighted the proposal for “New/revised EU green public procurement criteria integrating new circular economy requirements for road design, construction and maintenance”.
In this context, Asphalt is one of the best tools for our Administrations to meet such requirements, as at the end of its service life, it can be re-used 100% to build a new road. At the same time, current technologies allow the construction of new roads with a content of Reclaimed Asphalt up to 90% in hot and warm mixes and 100% in cold recycling.
One of the greatest technological milestones to achieve this was the use of rejuvenators, which, by restoring the flexibility, cracking resistance and rheological properties of the mix, without reducing other important properties, allow the addition of high quantities of reclaimed asphalt in new pavements.
There is nowadays an increasing demand to classify various products on the market as “rejuvenators” and a great deal of research projects on this topic. However, there is not any harmonised method for the assessment and classification of these products. In 2018, EAPA, the European Asphalt Pavement Association, published a Guidance Document where the best knowledge of each country was included, covering different levels, from plant to unit control.
Due to the great feedback received from the industrial community and with the aim of maximising the dissemination and outreach of EAPA’s work, the Association is organising the 1st EAPA Workshop on the use of rejuvenators in asphalt mixtures.
