Home/45 power gradation chart for aggregate

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).

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.

The correct percentage of individual sizes of aggregate in Hot Mix Asphalt (HMA) is of prime importance in establishing the parameters necessary for better performance of HMA.

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.

Draw a straight line between the lower left corner of the chart and the percent point for your largest sieve size that retains material.

This paper presents the results of an experimental investigation to determine the validity of 0.45power chart in obtaining the optimized aggregate gradation for improving the strength characteristics of highperformance concrete (HPC). Historically, the 0.45 power chart has been used to develop uniform gradations for asphalt mixture designs.
