The particle shape of aggregates is determined by the percentages of flaky and elongated particles contained in it For base course and construction of bituminous and cement concrete types the presence of flaky and elongated particles are considered undesirable as these cause inherent weakness with possibilities of breaking down under heavy loads

distribution (gradation) This test method uses a square open-ing sieve criterion in determining the gradation of soil between the 3-in (75-mm) and No 200 (75-m) sieves 1 2 The terms soils and material are used interchangeably throughout the standard 1 3 In cases where the gradation of particles larger than 3 in (75 mm) sieve is required Test Method D 5519 may be used 1 4 In cases

Gradation Test Pavement Interactive Gradation Types see Graph Aggregate gradation can be generally described by a few broadly defined gradation categories each one describing a general type of gradation These categories are Dense or wellgraded Refers to a gradation that is near the FHWAs 045 power curve for maximum density Read More

Broad coarse-aggregate gradation ranges are listed in Table 2 of ASTM C 33 These broad gradation bands are for use all across the country Once a gradation is selected for a project maintaining the gradation within tight ranges will achieve greater batch-to-batch consistency This is typically accomplished by properly stockpiling aggregates and reworking stockpiles to counter excessive

Part II Gradation within the Coarse Aggregate Fraction When designing the shape of a gradation curve in the coarse aggregate fraction (larger than 2 mm) it is worthwhile to pay attention not only to the percentage of grains larger than 2 mm (retained on a 2 mm sieve) but also to the ratios of contents of various coarse aggregate fractions
