Abstract
Generally, in engineering construction, soil lime stabilization is often used for sub-grade course and for the road bed. More recently, soil lime stabilization has grown more popular as a construction technique. However, the methodology for stabilization of banking slopes is not yet fully developed This paper investigates agricultural considerations as opposed to engineering research.
The authors studied this problem and have attempted to develop a suitable method for soil stabilization considering agricultual problemes.
In the experiment, the authors investigated the case of spriyed sodding on a slope treated with lime, and they conducted pot tests in order to pursue an investigation, for grass. Kanto loam soil was used and stabilized with industrial lime.
The results obtained are as follows:
1) For a 30% addition rate of lime, the pH is higher and grass growth is poor, but does grow.
2) For up to a 10% addition rate of lime, there is very little influence on grass growth.
3) Addition of superphosphates at 30% soils in addition to lime shows a notable effect.
4) When soil hardness is nearly 20 mm, grass growth is good.
