Bituminous concrete capable of self-healing fast under microwave action, manufacturing method and repairing method thereof
The invention relates to bituminous concrete capable of self-healing fast under microwave action, a manufacturing method and a repairing method thereof. The microwave self-healing bituminous concrete is prepared from, by mass, 83.8-88.3% of thick and thin aggregates, 2.3-7.9% of limestone mineral powder, 4.4-5.8% of bitumen, 2.1-8.5% of soft magnetic ferrite powder and 0-0.3% of fibers. Through stirring, the soft magnetic ferrite powder is evenly dispersed in bitumen mortar, the loss factor of the bituminous under microwaves is increased to over 0.16, when microwaves act on the damaged road surface made of the microwave self-healing bituminous concrete, soft magnetic ferrite has dielectric loss and magnetic loss effects on the microwaves, the bitumen mortar converts microwave electromagnetic energy into heat energy, the temperature of the bituminous concrete fast and evenly rises to 45 DEG C-85 DEG C after the bituminous concrete is heated for certain time, and fast self-healing of the bituminous concrete can be achieved by means of the heat repair function of the bitumen.
