Asphalt - Chemie im Straßenbau Chemistry in Everyday Life

Roads are one of the defining features of modern civilizations, believe it or not. To me and I think most others, the state of the roads in a country gives an idea of the level of development. It does not surprise then that chemistry features quite heavily in how we make roads.

A request from a listener, I explore in this episode the chemistry of bitumen and the physical properties needed for a good road.

This podcast is still not reactivated, but if you have a topic that you are interested in and do not mind an extended waiting time until I get round to it, drop me a mail under chem.podcast@gmail.com .
