ASPHALT HAVING SELF-HEALING FUNCTION USING MAGNETIC FIELD AND METHOD FOR REPAIRING CRACK THEREOF

摘要

PURPOSE: Asphalt having a self-healing function using a magnetic field and a crack repairing method thereof are provided to improve adhesion capability of an asphalt binder by heating a conductive fiber material in a cracked part by mixing conductive fibers heated by magnetic field inside the asphalt. CONSTITUTION: Asphalt having self-healing function contains a plurality of conductive fiber materials(2). Cracks are removed by inducing and heating the conductive fiber material by high frequency magnetic field. An emulsifier(3) is coated on the external surface of the conductive fiber body. A graphite-based reinforcing fiber material is mixed into the conductive fiber material. The magnetic field generator(5) generating high frequency magnetic field approaches the surface of the asphalt mixture and the conductive fiber material in the asphalt mixture is heated.
