Difference Between Fine and Coarse Aggregate Civil

2021-4-23  The surface area of coarse aggregate is less than fine aggregates. 6: Function in Concrete: The voids between the coarse aggregate are filled up by fine aggregate. Coarse aggregate acts as inert filler material for concrete. 7: Uses: Fine aggregates are used in mortar, plaster, concrete, filling of road pavement layers, etc.

Subgrade Preparation for New Pavements Pavement

Generally, adequate density is specified as a relative density for the top 150 mm (6 inches) of subgrade of not less than 95 percent of maximum density determined in the laboratory. In fill areas, subgrade below the top 150 mm (6 inches) is often considered adequate if it is compacted to 90 percent relative density.
