Dear List Members In the context of an interest we have in better understanding the significance of the dust released by road surface wear, I'm trying to track down up to date literature review material in areas of (i) the constituents of the materials used to build road surfaces and (ii) the characterisation of the wear and errosion processes of road surfaces, especially those that result in the liberation of airborne particulate matter. Analogous processes associated with tyre wear are also of interest. I would be happy to consolidate responses received and share with the list, if that would be of interest. With thanks. -- Prof. John Polak Head of Centre for Transport Studies Department of Civil and Environmental Engineering Imperial College London London SW7 2AZ T: +44-(0)20-7594-6089 F: +44-(0)20-7594-6102 http://www.imperial.ac.uk/transport-studies *********************************************************** The ROAD-TRANSPORT-TECHNOLOGY mailing list is published by International Forum for Road Transport Technology www.ifrtt.org ***********************************************************
