“Modelling and design of rubberised asphalt for railways sub-ballast”



About Me!

This is Natalia Colinas.

She was born around 27 years ago in a small village called El Valle located in the north-west of Spain inside the region of El Bierzo.

She studied primary and secondary school in her hometown. During the high school she was so lucky that she found one of this kind of teachers that are able to open a window inside your mind that didn’t seem to exist. Trough this window inspiration, motivation and passion for maths and science started growing exponentially.


As soon as the high school was finished, she knew that she wanted to become a Mechanical Engineer, so she moved to Gijón (Asturias) in order to start the studies of Mechanical engineering at the University of Oviedo.

Before finishing her university studies, by doing he master thesis, she had her first contact with the research world. Her master thesis took place in Ikerlan, a research centre located in Arrasate- Mondragón (Basque Country). There she learnt that she wanted research as way of life.

Once finished University, she started working as Mechanical Engineer in a company called Innovalia Metrology located near Vitoria-Gasteiz (Basque Country), where she lived before leaving Spain.

While she was working, the opportunity of being part of the SUP&R ITN appeared and she couldn’t let it pass by. Now here she is, the ESR9 of the SUP&R ITN project.

ESR9, the project!

“Modelling and design of rubberised asphalt for railways sub-ballast” is the name of the ESR9 project of the SUP&R ITN.

This project is taking place in the Department of Civil, Environment and Material Engineering (DICAM) of the University of Palermo. The supervisors of this project are the Professors Mario Di Paola and Gaetano Di Mino.

This project is focused on the study of the use of rubberised asphalt in the sub-ballast layer of the railway superstructures. There are already a few studies related to these applications, but more research is needed in order to have a proper design procedure, to model the long-term performance and also to understand its sustainability.

This project aims to create a model, based on the fractional calculus, to predict mechanical behaviour and the performance of railway infrastructure with sub-ballast made of rubberised asphalt, taking in account the economic and environmental aspects of this application.
