Evaluation of sweepers’ ability to reduce road dust load in street and tunnel environments in Trondheim
Overview
Objectives:
To avoid exceeding the environmental air quality standards for particulate matter (PM10) Norwegian Public Roads Administration Directorate of Public Roads (Statens vegvesen Vegdirektoratet) in Trondheim has implemented an attempt to clean a road tunnel and a stretch of road with three different cleaning machines to reduce the amount of dust of the road.
A large number of other tests is presented in the main report, while the present report focuses on how large the road dust depot has been before and after cleaning with different machines in the different environments.
Methodology:
In the framework of the project the effect of three different cleaning machines will be studied in two different environments. The two environments have been closed to traffic to allow study, one night per environment. First will be carried out measurements on all routes which should then be cleaned, then all the sections will be cleaned and finally it will be carried out new measurements of the distances that have been cleaned.
