Features: The decline in the quality of highway pavement usage, including subsidence, compression, shoving deformation, improper road crown, reduced smoothness, and various cracks, is attributed not only to the reasons of the pavement structure layers themselves but more to the subgrade and foundation. Solving the problems in the subgrade and foundation is a crucial aspect of improving the quality of pavement usage. The authors of this book have all worked in Shanghai, experiencing that maintaining the quality of highway pavement usage in Shanghai hinges on subgrade compaction and treatment of soft soil foundations. The book consists of 17 articles, reflecting the authors' many years of experience in design, construction, and research related to subgrade compaction and soft soil foundation treatment. The content covers five aspects: ① Discussion on the decline in pavement usage quality; ② Subgrade fill compaction and foundation treatment; ③ Total settlement calculation and design research experience for soft soil foundations; ④ Engineering applications of dynamic compaction and vacuum dewatering methods for soft soil foundations; ⑤ Optimization design examples for soft soil foundation reinforcement treatment.
