Asphalt pavement construction technology is an industry branch that undergoes constant development. Analyzing the directions of the development, one can divide it into two mainstreams: the development of roadworks equipment and the development of roadworks technology. Microwave heating technique has been mentioned in the road industry from the early ‘70s, but research records from practical full-scale use are very rare. This article presents the evaluation of the possible use of microwave heating technique during a particular aspect of the construction process, namely, the formation of longitudinal joints and the potential repair process of the cracked asphalt pavement. Research results showed that joints constructed using microwave-assisted heating performed the same or even better with regards to tensile characteristics comparing to other techniques. Also, the highest level of compaction was reached among the other tested techniques applied to the wearing course level. The second part of the research experiment showed the large potential of the microwave crack healing technique. The asphalt pavement was healed on its full depth of 10 cm with the single healing operation applied. Although some limitations may occur in the practical use of microwave heating, the test results suggest that it is a very promising technique and should be further developed (for, e.g., shielding concerns, electricity supply). The microwave heating technique is powered with electricity, which is important when there is a constant need for further reductions of CO2 emissions. It can be reached in parallel with clean energy or clean electricity sources.

“…In addition, rapid inspection can be achieved, as a large area can be inspected within a short time. Compared with the available thermal excitation methods, such as thermal lamps, laser, ultrasonic and pulsed eddy current (PEC), microwaves can provide more uniform, volumetric and selective heating [48][49][50]. If the penetration depth of the microwave signal is much smaller than the sample thickness, only the material within the penetration depth is heated and the rest of the material is heated by thermal conduction.…”

Carbon fibre-reinforced polymer (CFRP) composites have been increasingly used by aerospace and other industries for their high specific stiffness and strength properties. When in service, nondestructive testing (NDT) methods are required to monitor and evaluate the structural integrity. Microwave-based detection techniques offer the advantages of non-contact, no need for a coupling medium or sensors bonded to the object surface and relatively easy setup. This paper is intended to provide a comprehensive overview of the currently available microwave techniques appropriate for carbon fibre/polymer composites. The electromagnetic properties of carbon fibre composites associated with microwave testing are discussed first. Then, the microwave methods are categorised into self-sensing methods, near-field induction methods, near-field resonance methods, far-field sensing methods and the methods with combination of other NDT (e.g., microwave-based thermography). Principles and applications of each kind are demonstrated in detail. Discussions of the advantages and limitations in addition to research trends of microwave testing methods are presented.
