Ancona, Italy
Good morning to everyone, my name is Helena Lacalle and I am the early stage researcher number 1 from the super itn. I am working on a project entitled Pavement design for cold recycled materials and the institutions involved are AECOM where I am based, and the university of nottingham where I will get my PhD.

2. PAVEMENT DESIGN FOR COLD RECYCLED MATERIALS
Background of the problem
Sustainability approach
Avoid waste generation
Reduce raw materials consumption
Save energy
Recycling
Tar
So, why this project? Well, there are three main reasons: the first one is that pavements need rehabilitation after being in service, and the problem is that some old layers contain tar.
Sustainability: avoid waste generation and raw material consumption.
Cold technologies

6. Obtain inputs for design software
Future work
Permanent deformation
Fatigue
Long term performance
Obtain inputs for design software
Analyse pavement structure with cold mix characteristics
Develop design guide
Performance tests
Calibrate it
