Abstract
Real-time evaluation and optimization for compaction quality are necessary to implement automated subgrade construction. The compaction evaluation is followed by the modified compaction plan to ensure quality and enhance efficiency. This study proposes an intelligent hybrid methodology to automatically estimate the compaction quality and back-optimize the compaction procedure. A series of field tests are performed at the subgrade construction sites. Multiple operating conditions are considered, including varying vibration modes and compaction speeds. Referring to these data sets, the compaction quality is evaluated continuously, and the rolling parameters are dynamically optimized using the genetic algorithm. The compactness and homogeneity of the compacted soil are improved with the proposed intelligent methodology, providing an advanced solution to monitor and optimize the subgrade construction based on the currently available evaluation index.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
