The compaction quality of highway subgrade is a key link in ensuring road service life and driving safety. Aiming at the problems existing in current construction, such as uneven compaction degree, single detection method, and significant influence of environmental factors, this study conducts a systematic analysis focusing on compaction quality control technology. By sorting out the compaction mechanism, summarizing common detection methods, exploring the application paths of new monitoring and control technologies, and putting forward optimization suggestions combined with typical engineering cases, the research results show that scientific construction technology, advanced detection technology, and whole-process quality management are the core elements to improve the compaction quality of subgrade, which is of great significance for promoting the standardization and refinement of highway construction quality.
