Induced heating-healing characterization of activated carbon modified asphalt concrete under microwave radiation

摘要: Abstract This research investigates the crack healing ability of activated carbon (AC) modified asphalt concrete through microwave radiation. As a binder-based conductive additive, AC is expected to increase electro-magnetic radiation absorption binder. To verify this issue, neat and binders with different contents were exposed It was found that temperature binder increased considerably after heating compared observation can be regarded as driving force use in for purposes. Moreover, statistical analysis testing results showed modification did not have any detrimental effect on performance. For further evaluation asphalt, cycles breaking applied number semicircular bending (SCB) indirect tensile (IDT) samples. Notch length, damage level (number breaking-healing cycle), aggregate source significant effects induced efficiency. The obtained confirmed potentially viable robust component concrete.
