- Abstract
The pavement subbase is an important part of the pavement structure, and it is also the structural layer which is prone to appear quality problems in the pavement. As the main bearing layer, the pavement subbase plays a connecting role between the subgrade and the pavement. The practical engineering experience shows that strictly control of compaction degree can make the pavement structure to reach stable strength and guarantee the project quality. In this paper, the cement and soil curing agent are used to stabilize the natural gravel soil without sand and gravel area, and the Cement stabilized gravel soil is obtained by the design ratio. The cement stabilized gravel soil specimens are compacted with the vibratory compaction method in different compactness ,which is more suitable with the actual construction compaction mechanism. Then the 7d unconfined compressive strength of under the hierarchical compaction standard is measured, and the change relationships between the degree of compaction and the strength of the subbase is observed by the analysis of data . Finally, it is concluded that the strength of the subbase increases with the increase of the compaction degree in a certain compaction range, and the strength of the subbase can be improved by increasing the compaction degree.
