Gradation Test - Pavement Interactive

Basic Asphalt Materials Mixture Design and Testing

Coarse 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.

Reviewing asphalt test results | Asphalt magazine

GRADATION. The purpose of requiring a gradation on field samples is to help ensure that the asphalt plant used the same aggregates as reported on the asphalt mix design, in the same proportions. The gradation of all of the aggregates mixed together, plus the design binder content is …

Asphalt Aggregate Gradation and Size Testing with ...

Asphalt Aggregate Gradation and Size Testing with Industrial Scales In theory, there exists a particular gradation that, for a given maximum aggregate size, will produce a maximum density gradation and minimize the void space between particles.

CONSTRUCTION SPECIFICATION FOR HOT MIX ASPHALT

gradation testing according to Table 1. Draindown means that portion of stone mastic asphalt or stone matrix asphalt (SMA) mix, fines, and asphalt cement that separates and flows downwards through the mix. Fat Spot means an area of pavement substantially blacker than the surrounding pavement.

ASTM D6307 - 19 Standard Test Method for Asphalt Content ...

4.1 This test method can be used for quantitative determination of asphalt content in asphalt mixture and pavement samples for quality control, specification acceptance, and mixture evaluation studies. This test method does not require the use of solvents. Aggregate obtained by this test method may be used for gradation analysis according to Test Method D5444.

Sieve analysis - Wikipedia

A 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.
