Nonlinearity of cold recycled bituminous mixtures

Nowadays, the topic of environmental sustainability and eco-friendly materials is present in every area of daily life. This research project, in the field of civil engineering, deals with the study of particular materials used for the construction of road pavements that have as their strong point the fact that they are recycled from existing pavements at the end of their service- life (thus reducing or avoiding the extraction of raw material from quarries) and, above all, are laid at ambient temperature, thus considerably reducing CO2 emissions. This project aims to carry out laboratory tests on these materials in order to better understand their mechanical behaviour during their service-life. In scientific literature, it is still unclear how these materials behave when subjected to vehicular traffic load. The expected outcome is to formulate an empirical law that link the mechanical characteristic of the material (expressed by its stiffness) with number of cycling loads used for pavement design methods. This research will help to develop a methodology for flexible pavements design employing cold recycled materials mixtures.
