The project will explore how today's use of maintenance activities to minimize the appearance of dust in streets and roads can be optimized by experiments in tunnels. Different application (only roadside versus roadway versus wall-to-wall) and improved dust control agents is meant to be evaluated, as well as the comparison between normal use of a cleaning machine in the tunnel and dry vacuuming. Effects on both the storage pond at the road surface, and the levels of PM10, PM2.5 and NOx in the tunnel air will be studied. |
