Method for Assessing the Amount of Rolling Required to Achieve Optimal Compaction of Pre-Rolled Asphalt Pavement

摘要

A ground penetrating radar device and/or other sensor such as LIDAR, pressure, or temperature sensors is mounted on a mobile device, and is adapted, during motion of the mobile device, to sense characteristics of asphalt pavement on which the mobile device is moving, prior to compaction of the asphalt pavement by rollers. A processor, functionally associated with at least one sensor, receives from the sensor signals relating to characteristics of the asphalt pavement on which the mobile device is moving, and computes, based on the received signals, at least one compaction characteristic of the asphalt pavement. The processor provides a mapping of computed desired change in compaction characteristics to regions of the asphalt pavement during the rolling process. During rolling, at least one sensor measures the change in compaction and assesses when the change in compaction matches the desired optimal compaction based on the pre-generated map.
