Wear particles from road pavement with rubber mixed bitumen : comparison with reference pavement (English)
Studded tyre wear of road pavements cause emissions of inhalable particles (PM10). Allowed concentration of PM10 is regulated by an EU directive which is implemented in an environmental quality standard in Sweden. One way of reducing pavement wear particles is to adjust the properties of the road pavement. In the present project the effect on particle emission from mixing milled tyre rubber into the pavement bitumen has been investigated. Tests were made using the VTI road simulator with one pavement containing rubber and one reference pavement. The concentrations and size distributions of the emitted particles were measured and their chemical and morphological properties examined. Altogether, the results show that mixing rubber into the pavement bitumen results in lower emissions of both PM10 and ultrafine particles, while there were no significant differences between their chemical compositions.
