The Prospect of Microwave Heating: Towards a Faster and Deeper Crack Healing in Asphalt Pavement

Microwave heating has been shown to be an effective method of heating asphalt concrete and in turn healing the damage. As such, microwave heating holds great potential in rapid (1–3 min) and effective damage healing, resulting in improvement in the service life, safety, and sustainability of asphalt pavement. This study focused on the microwave...

Reverse traveling microwave reactor – Modelling and design considerations

Microwave heating presents a potentially green alternative for energy supply to chemical and catalytic reactors as it can be based on the electricity from renewable sources. The Reverse Traveling Microwave Reactor (RTMR) is a novel heterogeneous catalytic reactor concept, based on the coaxial waveguide structure. The reactor has two microwave...

Accelerated healing in asphalt concrete via laboratory microwave heating

Self-healing of asphalt concrete (AC) is highly dependent on temperature, and its healing capacity increases with elevated temperatures. The main objective of this study is to investigate the effect of microwave heating on promotion of self-healing in AC. With this purpose, two types of AC specimens (neat AC without additives and conductive...
