| Through systematic experimental study with the decomposed mountain Rock material along the line of the Xian to Hanzhong expressway, this paper analysed the project geological properties,fundamental and physical characteristic of the decomposed mountain Rock material , and studied compaction properties, intensity properties and water stability properties of the decomposed mountain Rock material in different cases. Meanwhile , combined with the roller compactiong technology and quality control test in the sopt entity project construct , it has proposed the roller compactiong technology and quality control method of the decomposed mountain Rock material subgrade construction. |
