Research on Key Electromagnetic Model for Microwave Hot Recycling of Asphalt Mixtures

Abstract:

For uneven temperature distribution of infrared hot recycling of asphalt mixtures, principle and advantage of microwave hot recycling are introduced. Maxwell's equations are applied to build electromagnetic transmission model of recycled asphalt mixtures. Considering asphalt mixtures as dielectric substance, reflection and refraction of electromagnetic field are researched and model of standing wave ratio is built. Equation of magnetic attenuation is applied to contrast attenuation depths of different pavement materials. The results lay a good theoretical foundation to improve heating efficiency and choose pavement materials.
