What is it about?
A distinctive feature of CRM mixtures is their evolutive behavior. In this paper we describe a procedure for characterizing the curing process and compare different CRM mixtures based on their evolutive behavior. The procedure is applied considering two CRM mixtures with similar composition, but produced in different countries (Italy and Canada) and with different materials.

Why is it important?
We highlight that the mechanical properties of different CRM mixtures can be compared only if their evolutive behavior is properly caracterized. We stress the importance of a methology which allows to "measure" curing in a quantitive way. In this paper we use the approach based on the identification of two parameters: the first is related to the CRM properties in the long-term: the second is related to the initial rate of evolution of these properties.
Perspectives
The experimental work summarized in this paper is part of a fruitful collaboration between the École de technologie supérieure (ÉTS) in Montréal, Canada and the Università Politecnica delle Marche (UNIVPM) in Ancona, Italy. Sharing different approaches to cold recycling and different laboratory practice between the two laboratories was a great experience!
