Abstract EN
It is consensual that the self-healing property of asphalt concrete can repair the damage inside it during high temperature and rest period.
In order to not affect the traffic, the rest period of asphalt pavement is very short and uncontrollable; so, it is necessary to obtain enough high temperature in a limited time to achieve higher healing efficiency of asphalt concrete.
The purpose of this paper is to study the induction heating efficiency and healing behaviors of asphalt concretes doped with different conductive additives.
Steel fiber, steel grit, and steel slag were added to asphalt mixtures as conductive additives to prepare induction healing asphalt concretes.
The steel grit and steel slag were added to replace the aggregates of corresponding particle size by equal volume to ensure the consistency of asphalt concrete volume, which can avoid degrading the performance of asphalt concrete due to the change of porosity.
The induction heating efficiency and healing rate of asphalt concrete were quantified by infrared camera and three-point bending-healing experiment, respectively.
The results showed that the thermal properties of asphalt concrete changed with the addition of different conductive additives.
The asphalt concrete with steel fiber had the best induction heating property.
While steel slag had extremely weak induction heating speed, the better thermal insulation property of the asphalt concrete with steel slag resulted in a higher induction healing rate.
It was suggested to add steel slag to induction healing asphalt concrete to improve the healing rate.
