| Abstract: | The Key to form a fine structure of rock ballast subgrade lies in a valid compaction.By examples of reconstrucion and extension engineerings on Shen-Da Freeway,the paper combines the rolling technology with the dynamic monitoring technique in the process of compaction,conducts testing study of the extent of rock ballast subgrade compacting and the dynamic monitoring matters.Based on results of dynamic monitoring,the rolling technology is regulated in time and the treatments for feedback are carried out,ensuring the quality of rock subgrade in the construction. |
