Latest Patents

Jonas Grigas holds a patent for a "Real time asphalt pavement quality sensor using a differential approach." This invention is designed to measure asphalt density in real time by employing a differential method. The system consists of two sensors, one positioned in front of a roller and another behind it, which measure reflected signals from the asphalt. The difference in these reflected signals indicates the optimal compaction and density of the asphalt pavement. By analyzing the change in variance over successive passes, the invention determines when the optimal level of compaction has been achieved. This innovative technology is crucial for ensuring high-quality asphalt pavement.
