· Crushed Stone Sand Fine aggregate produced by crushing hard stone Crushed Grace1 Sand line aggregate produced by crushing natural gravel Coarse Aggregate Aggregate most of which is retained on 4 75 mm IS Sieve and containing only so much finer material as is permitted for
Gradation or particle size distribution is the dispersal of individual particle sizes across the entire sample Aggregate gradation is typically reported in graphical form by plotting each of the particle sizes on a semi logarithmic chart and drawing a best fit curve between the points The full procedure is outlined in ASTM C136 AASHTO T 27
·mixes when determined by the Region Materials Engineer may not require fine aggregate angularity of percent Aggregate samples representing each aggregate stockpile shall be non plastic if the percent of aggregate passing the mm No 8 sieve is greater than or equal to 10 percent by weight of the individual aggregate sample
·The gradation was found to affect the behaviour of the aggregate in that coarser gradations gave better strength and resilience values under conditions most similar to those found in the field From research and experience during the laboratory testing it was concluded that the coarsest blends became too difficult to realistically work with
soils and soil aggregate materials The type of test used by the Virginia Department of Highways for years has been the AASHO Standard T 99 test performed on the minus No 4 fraction only Granular base and subbase materials however commonly include from 35 to 70 percent plus No 4 aggregate which necessitates making a correction to
