Abstract:

The use of Recycled Plastic Pin (RPP) to stabilize shallow slope failure offers a great economic and construction benefit and has marked a notable recognition in the engineering community. RPP driven into the soil slope face may go beyond possible slip surface that provides an additional resistance force along the slip plane and increase the factor of safety. Natural structural element, wood lumber and bamboo are available in abundance in developing countries and can be utilized for slope stabilization. The objective of the current study is to compare the compressive strength of RPP, wood lumber and bamboo under different environmental conditions. Based on the ASTM standards and field conditions, three different strain rates were applied during the study. Moreover, different environmental exposures were considered, 1) Acidic condition 2) Alkaline condition and 3) Neutral condition that represent different clayey soils in Texas. The test results indicated that wood and bamboo possesses higher peak strength at the normal condition compared to RPP. However, the strength of wood and bamboo were decreased by 65% and 71% respectively under different environmental conditions, in contrast strength reduction for RPPs was insignificant. Therefore, for the pinning of the slope in United States, the wood and bamboo could be a better solution compared to the RPP for short term stabilization. However, for long term stabilization, RPP could perform better due to its environmental resistant behavior. Bamboo is available in most of the developing countries and could be utilized for the slope stabilization in both short term and long term conditions.
