Abstract
This research evaluates the feasibility of using magnetic induction to reduce the curing time and for the self-healing of cold asphalt mixtures. For this purpose, the traditional oven curing method was compared with two novel magnetic induction protocols for fast curing in terms of water evaporated, time and energy used; the resulting mixtures were evaluated mechanically. Then, by means of a rupture-healing-rupture test, the feasibility of healing the cold asphalt mixtures by magnetic induction was determined. In addition, the impact of healing by magnetic induction on the service life of the mixtures in the face of particle loss was evaluated. With the developments of this research, it is possible to conclude that fast curing by magnetic induction is a feasible option, which improves the resistance to particle loss but decreases its stiffness and indirect tensile strength of the samples. In addition, it is possible to heal the mixtures by magnetic induction, having an optimum healing temperature, which allows the increase of durability against particle loss.
