Abstract

The pavement material always supplied from riverbed or mine which located inside the forest. This lead to the animal and aquatic environments damages and habitat destruction. Finding of efficient and low cost alternative pavement material supplying methods by environmental consideration discussed as an important issue. In this study, the effect of Road Packer Plus to improve physical and mechanical properties of soil, as a as a superseded method to reduce the environmental damage is assessed. Various laboratory tests, including identify, Atterberg limit, compaction and California Bearing Ratio (CBR), were performed on control and treated samples with recommended percentage of producer (0.019%). The results of these Atterberg limit tests indicated that adding this material to soil decreased liquid limit, increased plasticity limit and finally decreased plasticity index. The result of compaction test showed that the adding of RPP mater lead to increased maximum dry density but the optimum water of soil remain constant. The result of CBR test showed that the adding of RPP mater lead to increased bearing capacity. But the amount of improvement was less than the producer company claim and was not significant from technical point of view. Therefore, this matter with proposed dose has no significant effect on improvement of soil properties.
