Abstract:

An experimental study is performed to improve the high liquid limit soil to fill the roadbed of Yongan-Ninghua expressway. Firstly, some important factors influencing the experiment results are found out; and the corresponding countermeasures are established. Then a number of laboratorial experiments are carried out to obtain the optimal proportion of gravel for different high liquid limit soils. The study contributes to the rational use of high liquid limit soil and provides reference to the design and construction of similar engineering.

Key words: high liquid limit soil, improvement, optimal proportion of gravel, experiment
