Soil improvement using recycled aggregates from demolition waste Available to Purchase

Fine-grained soils with an in situ water content above the optimum compaction water content show poor suitability for installation and compaction. This paper presents the findings of an experimental study on the improvement of such soils by adding recycled aggregates from demolition waste. The study covers nine different base soils with a wide range of plasticity and addition rates of up to 50 mass% of recycled aggregates with a grain size 0/4 mm. A comparative analysis of the results from the laboratory study focused on the following parameters: improvement effect, compaction characteristics, air void content and bearing capacity. Soil-related patterns in the changes of these parameters were identified. For any fine-grained soil under consideration for this method of soil improvement, the findings presented herein can thus be used as a first indicator of the achievable results.
