Title: Innovations by Joseph Drbohlav, III
Introduction
Joseph Drbohlav, III is an accomplished inventor based in Wichita, Kansas. He holds three patents that focus on advancements in asphalt technology and road repair systems. His innovative approaches aim to enhance the durability and longevity of road surfaces.
Latest Patents
One of his latest patents is a method for selecting an asphalt mixture for making an interlayer. This system is designed for repairing roads and includes a highly strain tolerant, substantially impermeable, reflective crack relief interlayer. The interlayer consists of a polymer modified asphalt binder mixed with a dense fine aggregate mixture. The design ensures that about 100% of the aggregate can pass through a 9.5 mm sieve. The interlayer mix is formulated using volumetrics and verified through a Flexural Beam Fatigue test and a Hveem Stability test. This innovative system can delay the first appearance of cracks and reduce their severity for several years compared to traditional hot mix overlays, ultimately extending the service life of pavements.
Another significant patent by Drbohlav is a method of selecting a high modulus layer binder. This method involves measuring the complex shear modulus of various binders at temperatures not exceeding 30°C and assessing the creep stiffness at temperatures near the lowest in-service temperature. The selection process for the asphalt binder is based on these measurements, ensuring optimal performance for high modulus layers in bituminous pavement. Additionally, the formulation method includes mixing stiff and soft asphalt binders to achieve desirable properties for the high modulus layer.
