Sand replacement density (SRD) tests are used to measure the in-situ density of natural or compacted soils using sand pouring cylinders The in-situ density is typically used for highway or pavement design purposes to estimate the relative density of base course or subgrade materials

Albano et al demonstrate that both larger particles and higher replacement percentages cause significant reductions in tensile strength due to an increase in voids present within the concrete This is supported by Frigione where 5% replacement by volume of sand using granulated PET led to only a 2% loss in tensile strength
