Fine Grading for Pavement - constructionmentor

Ideally the rough aggregate base will be brought to +/- 1″. The scope of the fine grading work will be to either cut or fill the material to match as close as possible to the finish pavement elevations, less the thickness of the proposed pavements. Finish grading work is most commonly done with a grader and a roller following behind.

GRADATION OF AGGREGATE FOR CONCRETE BLOCK

The aggregate was blended from fine (No. 4 to 0) and coarse (3/8 inch to No. 4) materials in proportions to yield the desired fineness modulus. It should be noted that the strengths given in Fig. 2 are on a gross area basis. The effect of grading of aggregate is shown in the bottom set of curves.

Grading of Fine Aggregate - CivilWeb Spreadsheets

Grading of Fine Aggregates - UK. In the UK the following grading of fine aggregates are often used. A total tolerance of around 5% is often applied to these percentages to account for minor deviations. Also the percentage passing the 0.125mm sieve can be increased to around 15% if manufactured fine aggregates are used.

Sieve analysis - Wikipedia

A sieve analysis (or gradation test) is a practice or procedure used in civil engineering and chemical 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.

Aggregate Gradation: Testing Tips and Tricks - Gilson Co.

ASTM C702 allows fine aggregate to be divided with a mechanical splitter if the material is drier than saturated surface-dry (SSD). For non-specification testing of some free-flowing aggregates with low fines content, you could consider splitting while still wet, but it can get messy. Coarse aggregate samples can be split at any moisture.
