HMA aggregate size and gradation design Constructed ...
Mar 02, 2009· Generally, HMA is characterized as either "Open graded" or "dense graded". Open graded mixes are generally used for friction courses and have larger top size aggregate, much higher voids, and essentially "gap" grading. Dense graded mixes have a more uniform gradation and may contain larger top size (3/4") or smaller top size aggregates (1/2" or ...

gradation of coarse aggregate is code
Gradation #1 (mortar gradation) or #2 (coarse aggregate gradation). According to ACI 506R05,1 the coarse aggregate size should be larger than 1/4 in. ( mm). As a guideline, it is believed the best results are obtained with Gradation #2, with a maximum aggregate size of 3/8 in. (10 mm), because this is what will promote an inplace
