Optimized design of an asphalt mixture railway track for ...

This paper describes the design process of a new asphalt slab track able to reduce vibrations induced by railway vehicles. In a first stage, the optimal dosage of the asphalt mixture including plastic waste is determined and the cross section designed. Then, a real stretch of asphalt slab track is built in an operating tram line in which real acceleration data sets are collected.
