- Abstract
- To overcome the deficiencies of recycled crushed glass and biosolids when used alone and to enhance their strength properties, the innovative idea of blending these two traditionally waste materials was studied. The Fine Recycled Glass (FRG) and Biosolids (Bio) mixtures were prepared in various proportions with FRG ratios varying from 20% to 80%. An extensive suite of geotechnical laboratory tests including particle size distribution, Atterberg limits, standard compaction, hydraulic conductivity, CBR and direct shear tests were undertaken on the blends. The test results indicated that the FRG/Bio blend has the advantage of combining the high friction characteristics of recycled glass with the cohesive characteristics of biosolids. Particle size distribution, compaction results, CBR values and shear strength of the optimum blends (40% - 60% FRG) validate their potential to be used as a fill material in road embankment applications. A preliminary finite element model was developed which further indicates that the aforementioned FRG/Bio blends exhibit acceptable response to the road and vehicle loadings and are therefore an attractive alternative to traditional quarried aggregates in road embankment fills.
