Recovery capacity of electroconductive asphalt mortars under the influence of magnetic fields

Innovations in pavement design and engineering: A 2023 sustainability review

“… Eco-friendly; strain-sensing capabilities; temperature-sensing capabilities; pressure-sensing capabilities; economically feasible; improved response time Requires further development and field-testing; can have high initial costs [ 111 , [112] , [113] , [114] , [115] , [116] ] Self-Healing Asphalt Pavements Smart Pavements Many self-healing asphalt technologies try to restore and utilize asphalt's inherent self-healing behavior. Technologies include additives and nanoparticles, in-situ heating, and rejuvenation using encapsulation, hollow fibers, or vascular fibers Increased pavement lifetime; reduces lifecycle costs; reduces emissions related to maintenance Many of the technologies need further testing before ready for application [ 111 , [117] , [118] , [119] , [120] , [121] , [122] , [123] , [124] , [125] , [126] , [127] , [128] , [129] , [130] ] Self-Healing Concrete Pavements Smart Pavements The leading process of self-healing in concrete pavements is through the introduction of bacteria to create calcium carbonate, which can fill microcracks Increased pavement lifetime; reduces lifecycle costs; reduces emissions related to maintenance; and some have proven to improve concrete strength, durability, and resistance Less explored than self-healing in asphalt pavements; slow overall process; unknown biological health effects [ [131] , [132] , [133] , [134] , [135] ] Information Interaction Pavements Smart Pavements Integrated framework design systems for entire road...…”

“…The fibers are then heated with induction heating, and the diffusion of the asphalt binder is activated [ 117 ]. Due to this activation, the asphalt has the ability to move and can thus seal cracks through capillary flow [ 126 ]. Contrary to induction heating, microwave heating does not require additives, therefore decreasing the cost and effort associated with the technology [ 118 ].…”

“…4 , using the effects of magnetic fields, the temperature of the binder can be manipulated as the magnetically and electrically responsive materials in the asphalt mixture are attracted to the static magnetic fields created by induction and microwave heating [ 127 , 128 ]. This thus induces the flow of the binder which can repair cracks [ 126 , 128 ].

Understanding the influence of filler type and asphalt binder content on the moisture and fatigue resistance of asphalt mortars

“…In order to minimise the air void influence on the study of the aggregate/binder adhesiveness and its evolution subsequent to water action, the compaction process targets a void content close to 0% as pointed out in other studies (27,39). Once compacted, the specimens were cut in order to obtain the prismatic specimens of 8.5 x 8.5 x 50 mm that would subsequently be used in the DMA (Dynamic Mechanical Analyzer) characterisation.…”
