Abstract

Induction heating is a novel maintenance technique which is applied to prolong the service life of the asphalt concrete by increasing locally the temperature and at the same time initiates the healing process of asphalt. To develop conductive asphalt mixes suitable for induction, in most cases many efforts were concentrated on adding fiber-type particles, such as steel fibers or steel wool. However researches on the performance of the induction heated asphalt mixes under aggressive environmental conditions is still missing. In this paper, a chloride conditioning assessment protocol is presented to evaluate the chloride-induced damage of the asphalt mixes by utilizing the Non-Steady-State Chloride (NSSC) migration method to accelerate the migration of chloride ions into the conductive asphalt mixes. The influence of chloride on the mechanical performance and induction heating efficiency of different conductive asphalt mixes at different conditioning levels was investigated.
