Gradation Techniques Tarantula Curve
The more popular methods for proportioning aggregate in slip formed pavements was used. These methods include the Shilstone Coarseness Chart, Individual Percent Retained Chart, Power 45 Chart, and 60% coarse aggregate and 40% fine aggregate. Below is a brief overview of each method.

Thus, the maximum density line appears as a straight line from zero to the maximum aggregate size for the mixture being considered (solid line in Figure 1).

Sieve analysis Wikipedia
2019101&ensp·&enspA sieve analysis (or gradation test) is a practice or procedure used (commonly used in civil engineering) to assess the particle size distribution (also called gradation) of a granular material by allowing the material to pass through a series of sieves of progressively smaller mesh size and weighing the amount of material that is stopped by each sieve as a fraction of the whole mass.
201925&ensp·&enspAs the fineness modulus factor increases, the aggregate gradation becomes coarser. Fineness modulus is calculated by dividing by 100 the sum of the cumulative percents retained on specified sieves.

201858&ensp·&enspCoarse gradation: A gradation that, when plotted on the 0.45 power gradation graph, falls mostly below the 0.45 power maximum density line. The term generally applies to dense graded aggregate. Mineral filler: Defined by the Asphalt Institute as a finely divided mineral product at least 65 percent of which will pass through 75um sieve.
