Stability Of Fine Sand And Grass-roots Structure Of Cement Dust Applied Technology Research

This paper researches the base made of the cement stability fine sand in materials composition designing, construction and pavement characteristic. Firstly, pointing to the characteristic of cement, lime treated soil, and stability fine sand with theory of ionic exchange, the research is made about how physical mechanics of mixture and construction method, and so on, influence its strength. On this ground, This paper also provides methods and procedures of materials composition designing in cement, lime treated soil, and stability fine sand, and base on pavement construction technology. We design three procedures in three different ways of construction method separately. At last, by using many examples of repairing the pavement base construction of cement, lime treated soil, and stability fine sand, we provide that it has good pavement mechanics property and analysis its economic efficiency. The research will provide good reference value in design and construction of the base structure.
