Herein is a discussion of the development of microwave applications in road maintenance for hot in-place pavement recycling, plant-mixed hot recycling, and the removal of snow and ice. The theory and implementation approach to microwave applications in nondestructive detecting of road disease is also included. Structural parameters design was found to highly influence the heating efficiency and uniformity of the microwave heaters. Microwave radiation shielding and production economics are also discussed. Microwave treatment of asphalt pavement surfaces is a promising candidate for road restoration and damage detection of pitch road surface. The microwave processes are robust, with high heating ratios, accurate non-destructive detecting and environmentally friendly recycling.
