Abstract
Self-healing technology is a new field in material technology. It is causing a transformation in materials engineering and revolutionizing the behavior of various materials which can make a new generation of asphaltic materials artificially healed while in-service which can extend the service life of asphalt pavement. This article provides an overview of investigations concerning the self-healing characterization and enhancement in the modified control mix (MCM) and modified RAP mix (MRM) by applying a microwave heating field at the surface of the mixtures while working by embedding steel wool fibers in the asphaltic mixtures. Marshall mix design was used for the design of HMA and SH-HMA mixtures for testing of Physical properties and compared with the control mixes. For MCM, the used percentage was 5% of S.W.F. which got healing percentages (93.2%, 77%, 63.9%) respectively, while the control mixtures healing percentages were ( 51.5%, 41.8%, 31.8% ) respectively. For MRM, the used percentage was 3% which got healing percentages (83.6%, 73.4%, 62. 5%) respectively, while the control mixtures healing percentages were (44.7%, 33%, 24.2%) respectively. The results of the experiment showed that the addition of steel wool can improve the self-healing behavior of HMA and the overall performance.
