The potential use of microwave energy to heat asphalt mixtures and pavements has begun attracting attention. Microwave heating is rapid, deep and uniform. With microwaves, heat is generated by the treated material under the excitation of an alternating electromagnetic field caused by the passing microwaves. Some materials such as water heat very well with microwaves, while others such as Teflon do not. Asphalt cement is similar to Teflon, but many aggregates seem to possess favorable microwave heating properties. This thesis focuses on pavement materials and their interaction with microwave energy as a heating method. The interaction between asphalt-pavement materials and the applied microwave energy was evaluated in two phases. First, the effect of microwaves on some properties of virgin and recycled mixtures was investigated. Potential benefits to adhesion and water-stripping resistance of asphalt film to aggregate are promising but need further investigation. Secondly, the effect of several mixture variables on microwave heating efficiency was also studied.
