APSE last results were presented at the final project workshop on Circular Economy in the construction sector

by Andrzej Długołęcki in News

The APSE Conference “Promoting Circular Economy for a Greener Road Construction”,   organised by Comunidad of Madrid in cooperation with ACCIONA held on November 22 in Madrid, presented practical examples that contributes to a circular economy model in the road construction sector.

Beside the  main outcomes of the APSE project, the workshop addressed issues such as Spain’s circular economy strategy, incorporating this model into public initiatives at different levels and applying it to the construction sector, especially regarding regulations and successful stories.

Representatives of public administrations, private companies, academia and associations were joined together to share their experience with the audience.

Abstract

Bitumen is a commonly used material for road construction. According to environmental regulations, vegetable-based materials are applied for binder modification. Fluxed road bitumen containing a bio-flux oxidation product increases the consistency over time. The efficiency of crosslinking depends on the number of double bonds and their position in the aliphatic chain of fatty acid. The main goal of this paper was to examine the structural changes taking place during hardening bitumen with bio-flux additives. Two types of road bitumens fluxed with two different oxidized methyl esters of rapeseed oil were used in this study. Various chemical and rheological tests were applied for the fluxed-bitumen at different stages of oxygen exposure. The oxidation of rapeseed oil methyl ester reduced the iodine amount by about 10%–30%. Hardening of the fluxed bitumen generally results in an increase of the resins content and a reduction of the aromatics and asphaltenes. In the temperature range of 0 °C to 40 °C, bio-flux results with a much higher increase in the phase angle than in temperatures above 40 °C in the bitumen binder. The increase in the proportion of the viscous component in the low and medium binder temperature is favorable due to the potential improvement of the fatigue resistance of the asphalt mixture with such binders.
