Review of the Application of Microwave Heating Technology in Asphalt Pavement Self-Healing and De-icing

Abstract

In the past decades, a large amount of research was conducted to investigate the application prospect of microwave heating technology in improving the efficiency of asphalt pavement self-healing and de-icing. This paper reviewed the achievements in this area. Firstly, the properties of asphalt concrete after microwave heating were summarized, including microwave sensitivity and heating uniformity. Then, the evaluation indicators and influence factors of the self-healing properties of the asphalt mixtures heated by microwave were reviewed. Finally, the application of microwave heating in asphalt pavement de-icing was explored. In addition, asphalt pavement aging due to microwave heating was also reviewed. It was found that microwave heating technology has good prospects in promoting asphalt pavement self-healing and de-icing. There are also some problems that should be studied in depth, such as the cost-effectiveness of microwave-sensitive additives (MSAs), the performance of the pavement with MSAs, mechanism-based self-healing performance indicators, and the aging of asphalt pavements under cycling microwave heating.

Defect Detection in CFRP Concrete Reinforcement Using the Microwave Infrared Thermography (MIRT) Method—A Numerical Modeling and Experimental Approach

“…The present study suggests the utilization of microwave irradiation as a heating method. Microwave heating has been widely employed in the literature for various purposes related to concrete structures, including expediting the curing process, decontaminating cement, and facilitating the drilling or melting of concrete [24][25][26][27]. In this proposal, microwaves are suggested as a potential energy source for infrared thermography [28][29][30][31][32][33][34].…”

Quantitative Analysis of Genomic DNA Degradation of E. coli Using Automated Gel Electrophoresis under Various Levels of Microwave Exposure

“…In terms of microwaves, there are numerous applications, for example, microwave radiation is useful in analytical and environmental chemistry, pretreatment, sample processing in research, food sterilization, drug discovery, large-scale drying, mineral processing, and chemical synthesis [55][56][57][58][59][60]. Recently, the application of microwave technology has been evaluated in manufacturing technology; road construction and de-icing; catalyst production; application as an absorbent in oil shale; solidification of copper; and polymer production [61][62][63][64][65][66]. The nature of this study, however, was limited to improving our existing understanding of microwave radiation's impacts on environmental bacteria and evaluating the impacts of microwave levels on DNA integrity.…”

Smoothing and Cicatrization of Isotactic Polypropylene/Fe3O4 Nanocomposites via Magnetic Hyperthermia

“…An interesting example is that of Bouteiller et al, who tentatively addressed these limitations by chemically modifying a commercial (relatively strong and tough) thermoplastic polyurethane (TPU) in order to enable its self-healing without major loss of mechanical properties. 11 Apart from increasing the complexity of chemical architectures, materials healing can be envisaged through the application of various physical stimuli including, but not limited to, convective heat, microwaves, 12,13 laser radiations, 14,15 and magnetic oscillatory fields. 16−20 In the latter case, stimulus healing is achieved by irradiating micro-or nanoparticles (NPs) embedded into a thermoplastic polymer matrix with an oscillatory magnetic field (OMF) of several hundreds of kilohertz and 5−50 mT, generating heat through magnetic hysteresis loss.…”
