As water and wastewater are composed of mixtures of mineral and organic constituents under dissolved, colloidal, or suspended solid forms, the measurement of aggregate parameters is often more adapted than specific analysis for water quality characterisation or monitoring.
Soil structure describes the arrangement of the solid parts of the soil and of the pore space located between them. It is determined by how individual soil granules clump, bind together, and aggregate, resulting in the arrangement of soil pores between them. Soil structure has a major influence on water and air movement, biological activity, root growth and seedling emergence.
TOTAL MOISTURE CONTENT OF AGGREGATE BY DRYING AASHTO T 255 SCOPE The moisture content in aggregate is used to determine the binder content for HMA during production of the mixture in a plant.
