Title: Innovations by John Wiley in Asphalt Technology
Introduction
John Wiley is an accomplished inventor based in Leander, Texas, with a notable portfolio of five patents. His work primarily focuses on advancements in asphalt technology, particularly in the treatment and recycling of asphaltic materials.
Latest Patents
Wiley's latest patents include a "Recycled asphalt drum dryer having a low NO.sub.x burner" and a "Method of producing hot mix asphalt." The first patent describes an apparatus designed for the treatment of 100% reclaimed asphaltic pavement (RAP). This innovative system utilizes low temperatures and avoids direct radiation from a burner flame to the RAP. The RAP is heated in a counter flow drum, which is supplied with hot combusting gases generated by a remote low NOx burner. The input gases are ideally around 1100 degrees Fahrenheit, while the output temperature may be 100 degrees Fahrenheit or less than the input temperature of the RAP. Additionally, the RAP can be heated using a microwave oven to achieve a final temperature, although this step is not mandatory in the counterflow design.
The second patent outlines a process for producing hot mix asphalt (HMA) by treating virgin material or incorporating up to 100% RAP. The HMA is heated in either a parallel or counter flow rotating drum, supplied with hot combustion gases from a remote low NO.sub.x burner. The temperature of the gases entering the drum ranges from about 400 to 2,000 degrees Fahrenheit, while the exiting gases range from about 130 to 220 degrees Fahrenheit. The process also includes options for subjecting the material to microwave radiation to raise its temperature or to reorient dipolar molecules without significant heating. The exhaust gases are treated to ensure environmental safety, passing through a knockout box and a baghouse before being processed through an oxidizer.
