Field compaction is crucial for stabilizing soils. Factors like water content, compaction amount, and delay after mixing affect compaction. A study using different soils, fly ashes, and lime found that the best moisture for maximum strength varies with soil type. Temperature doesn't significantly impact strength. Minimizing delay between mixing and compaction is vital for soil-lime-fly ash mixtures with clay particles. Using a modified compactive effort can increase strength significantly compared to the standard method.
