“…This means they have the capacity to facilitate the movement of water, which is a valuable property in many engineering applications, particularly in drainage and geotechnical engineering. The existence of a significant disparity in hydraulic conductivities for materials collected from different stockpiles, even when the materials are of the same type, can be attributed to several factors such as material variability (particle size distribution, mineralogical composition), gradation and particle packing (particle size distribution and packing arrangement of materials) and contaminants and impurities [43][44][45].…”

In this study, the variation of shear strength behavior and particle breakage (after shearing), as a function of moisture state and compaction level, is investigated for recycled concrete aggregate blended with recycled clay masonry. Recycled masonry was blended with concrete aggregate in percentages ranging from 0% to 30% by total weight. Tests include; basic engineering characteristics (particle size, modified compaction, hydraulic conductivity, and California Bearing Ratio, CBR) as well as unconsolidated undrained static triaxial testing. In triaxial tests, moisture levels ranged from 60% to 100% of optimum moisture content, but compaction levels ranged from 90% to 98% of maximum dry density. The hydraulic conductivity for blends is approximately 2x10-6 cm/s, which indicates a relatively low hydraulic conductivity. Results show a proportional linear relationship between the shear strength of blends and the level of compaction. Despite this, both apparent cohesion and shear strength exhibited reverse linear trends. As expected, more compaction effort resulted in more particle breakage. Strict control should be performed over the compaction process to achieve the required compaction level which resulting in pavement materials being stiffer.
