A Study of Asphalt Recycling Process of Microwave Pre-Heating
Normally roads are mostly constructed of asphalt concrete. Roads, when used for a long time, usually become damaged. In the future, the road surfaces will be demolished and rebuilt to improve the quality from the old materials, in other words, recycling. In order to maintain the properties of asphalt, it must be preprocessed to allow it to retain its elastic deformation properties. In the past, asphalt was recycled by direct convection heating with fuels such as gas, oil, coal, etc., however, this method caused the asphalt to heat unevenly from the outside in, resulting in poor performance. Much more fuel is also required to heat the asphalt evenly, which leads to undesirable physical changes. This research is to study the use of microwave energy to allow for more evenly distributed heating of the asphalt. With it, the heating happens from the inside out, and decreases the unwanted physical property changes, which produces a higher quality end result, depending on the energy and time used to get these results. Initial revelation and results of the proposed process can be applied to the design and creation of an effective drying device for asphalt road surface, as well as reducing energy consumption.
