Abstract:
For the purpose of ascertaining the temperature distribution in recycling asphalt mixtures, the nonlinear processes of microwave heating was studied taking dielectric permittivity and specific heat of asphalt mixtures as temperature-dependent parameters, which resulted in a nonlinear variation of electromagnetism field distribution and microwave power absorption. A nonlinear two-dimensional thermo-electromagnetic coupling model for the electromagnetic and the heat transfer processes equations is proposed, and a solution approach based on an alternate iteration with a time-step of microwave cycle is suggested. By continuous or interanittent radiation heating experiment with a microwave power system in 2.45 GHz, it is shown that instantaneous volume heating can be achieved by microwave heating through radiation heat transfer. The microwave heating is characterized by its rate, uniformity and non-pollution in hot in-place recycling.
