Live compaction data can also help you recognize potential problems before they occur. Edwards offers the example of a roller crew that can reach a compaction level of 8 across most sites but only a 4 in a particular location. This may be an indicator of a failing utility below the road or a problem spot in the gravel base that should be investigated before the job is completed.
当设置在平板电脑上的机器, BOMAP Connect uses the tablet's GPS signal to plot the machine's location. 在机器上加一个GPS天线可以提高精度, 定位精度可达20厘米. This is more than enough accuracy for a roadway or similar project, 爱德华兹说. Millimetre accuracy can be achieved by connecting to base stations on the site.
"Most of our customers have found that the 20 centimetre accuracy works for them. Generally, we are overlapping passes slightly anyways to ensure overall coverage," he notes.
