Abstract
Road bed cement soil treatment is an effective means of highway subgrade treatment,which can significantly improve the mechanical properties of soft soil subgrade.Through taking A highway project as an example,the study introduces the parameter design of cement soil control technology by combining theory and practice,including the selection of cement varieties,determination of cement dosage,construction preparation,and mix ratio design,etc.The study analyzes the construction technology and quality evaluation technology of cement soil treatment,and puts forward the technical optimization measures:to speed up cement consolidation,improve the adaptability of construction machinery,optimize maintenance measures,adopt a variety of methods to comprehensively evaluate the consolidation effect through strict control of mixing,paving,rolling and maintenance,etc.,optimize all details,improve the overall quality and safety of China's highway engineering,so as to provide experience and reference for similar projects.
