Abstract
For the purpose of utilization of paper sludge generated from pulp/paper manufacturing company as base material for greening slope, this study investigated base physical properties and rainfall erosion resistance of a base material for greening slope manipulating mix ratio of paper sludge, and conducted a growth test of plant under the condition using the base material. Additionally, this study examined the workability and long-term growth test of plant on a test field. As a result, we found that the increase in the number of pore related to an air permeability and permeability, and the favorable growth condition of plant when a base material for greening slope was mixed a paper sludge. Moreover, we showed improvement of the rainfall erosion resistance when a base material for greening slope was mixed with paper sludge of 6～10%. As a results of the test field, we found no construction failure, and showed excellent growth of plant after six years from the execution. These results showed a high possibility that paper sludge is utilized as material for the base material for greening slope.
