  • Sand Equivalent - Pavement Interactive

    OverviewBackgroundTest DescriptionThe sand equivalent test (Figure 1) is a rapid field test to show the relative proportions of fine dust or clay-like materials in fine aggregate (or granular soils). The term “sand equivalent” expresses the concept that most fine aggregates are mixtures of desirable coarse particles (e.g., sand) and generally undesirable clay or plastic fines and dust (ASTM, 2003).These materials can coat aggregate particles and prevent proper asphal在pavementinteractive.org上查看更多信息
