Richard Walter May is an accomplished inventor based in Wichita, KS (US). He holds 2 patents that showcase his expertise in the field of asphalt technology. His innovative approaches have contributed significantly to the development of more efficient and environmentally friendly materials.

Latest Patents

One of Richard May's latest patents is a method of making a sulfur-extended asphalt mixture. This method minimizes hydrogen sulfide gas release into the atmosphere by utilizing sulfur granules with specific physical properties. These granules are created by successively coating a starting sulfur seed particle with liquid sulfur, which solidifies between coatings to achieve a desired particle size. The resulting sulfur granules are then used in the preparation of a sulfur, bitumen, and aggregate mixture, providing a sustainable solution for asphalt production.

Another notable patent is for a reflective crack relief pavement interlayer with improved load-bearing capacity. This interlayer is designed to be highly strain tolerant and substantially moisture impermeable. It includes a polymer-modified asphalt binder mixed with a dense fine aggregate mixture containing a significant amount of manufactured sand. The design of the interlayer mix is based on fatigue and stability tests, ensuring compatibility with local traffic and climate demands. This innovative interlayer can delay the appearance and severity of cracks for several years compared to traditional hot mix overlays, ultimately extending pavement service life.
