摘要
A real time differential asphalt pavement quality sensor of the present invention is adapted to measure asphalt density in real time using a differential approach. Two sensors, one in the front of a roller and another behind the roller, measure reflected signals from the asphalt. The difference between the reflected signals provides an indication of the optimal compaction and density of the asphalt pavement. The invention looks at the change in variance over successive passes to determine when the optimal level of compaction has been reached.
