摘要

本研究旨在通过添加废塑料和叶灰混合物来研究三种土壤的岩土力学特性。研究中使用的土壤稳定剂是废弃塑料文件夹中的塑料条和斯里兰卡五种天然火山灰叶子的灰烬混合物。本研究中使用的塑料宽度为5mm，长宽比为1,2,3和4，重量百分比为0.5,1,2,4和8。所使用的叶灰混合物的重量百分比为2,4,6,8和10。研究了土体的最大干密度(MDD)、最佳含水率(OMC)、浸水加州承载比(CBR)、抗剪强度参数、塑性指数(PI)和Atterberg极限等岩土力学特性的改善。结果表明，在土壤中添加2%的塑料和6%的叶灰混合料，可获得浸渍CBR和MDD的最佳改善效果。抗剪强度参数和PI也可以得到改善。

Effectiveness of Pozzolanic Leaf Ashes and Plastics on Geotechnical Characteristics

This study aims to investigate the geotechnical characteristics of three soils by adding waste plastics and a mixture of leaf ashes. The soil stabilizers used in the study are the plastics strips from waste plastic file folders and a mixture of ashes from five naturally occurring pozzolanic leaves in Sri Lanka. The plastics used in this study have a width of 5 mm and aspect ratios of 1, 2, 3, and 4 in the weight percentages 0.5, 1, 2, 4, and 8. The mixture of leaf ashes used is in the weight percentages 2, 4, 6, 8, and 10. The investigated geotechnical characteristics of the soils include the improvement of maximum dry density (MDD), optimum moisture content (OMC), soaked California bearing ratio (CBR), shear strength parameters, plastic index (PI), and Atterberg limits. The results suggest that the optimum improvement in soaked CBR and MDD can be achieved by adding 2% plastics and 6% leaf ash mixture into the soils. Shear strength parameters and PI can also be improved.
