Abstract:
Based on engineering practice of Jingbian—Yanan freeway and a large amounts of field experimental datum. The paper discussed the construction craft, quality control, the field test means of low liquid limit clay, studied the machines choice for the compaction of the clay, the reasonable laminated thickness of roadbed filling, the compaction effect control and the measuring technique. The results of show that the reasonable laminated thickness of roadbed filling is 30cm,the water content of roadbed filling is more +1% than the optimal water. The number of rolling by sheepfoot roller is about six or seven times, the number of rolling by 20 t vibrating roller is about four or five times, the static surface compactness; This notes that the low liquid limited clay is the appropriate filler of embankment construction, and should be fully utilized in its plentiful area. 4 tabs, 10 figs, 8 refs.
