Project Spens – Sustainable Pavement for European New Member States

Abstract

This paper represents the main results of work package 5 of the SPENS project (Sustainable Pavements for European New Member States) that was focused on assessment of the impact of roads on the environment and where the Faculty of Civil Engineering of University of Zilina was the most active and closely cooperated with CDV.
Collaborative international project was focused on particulate matter (PM) production due to mechanical abrasion of road pavements. PM (and noise emission) was captured next to roads with different pavement types (stone mastic asphalt and asphalt concrete) by middle volume samplers with consequent gravimetric analysis of each exposed filter. The content of organic and inorganic pollutants fixed to PM was determined to characterise the PM composition. Dust fall measurements including mass and chemical composition determination in road tunnels with different pavements (cement concrete and asphalt concrete) were done to determine the pavement abrasion contribution to overall PM emissions in tunnels.
