Development of Low Emission Asphalt Mixtures for Urban and Peri-urban Roads
Summary
Researchers developed low-emission asphalt mixtures through the EU Horizon 2020 NEMO project designed to reduce both road traffic noise and NOx concentrations in urban and peri-urban driving environments, evaluating their noise mitigation and air quality performance.
The application of low noise road surfaces has proven an effective mitigation measure and has the potential to lower the level of road traffic noise significantly.In the EU Horizon 2020 research and innovation project NEMO new asphalt mixtures have been developed to mitigate the road/vehicle related emissions, for both urban and periurban driving circumstances.Apart from the ability to reduce traffic noise, the asphalt also exhibits capabilities for suppressing the concentration of NOx from the vehicle exhaust.The paper presents the process of drafting a functional description, designing the low noise asphalt mixtures and performing laboratory tests, to finally result in two low emission asphalt types, for urban and peri-urban roads.The greatest challenge is to answer the targets for noise reduction and suppression of exhaust NOx without jeopardizing the durability of the road surface.The behavior of the asphalt under real traffic conditions is simulated with an accelerated pavement test device.This test makes it possible to evaluate the long-term (up to 20 years of heavy traffic or 10 6 loads) durability in a few months.he abstract should be placed below the title, list of Authors and affiliations.It should contain a maximum of 200 words.

Exploring the effect on the environment of encapsulated micro- and nano-plastics into asphalt mastics for road pavement.
This study tested whether encapsulating waste plastic material into asphalt for road pavement reduces environmental release of micro- and nanoplastics compared to conventional asphalt. The results suggest that this approach can reduce plastic fragment release into the environment while providing a practical use for plastic waste in road infrastructure.
