FOP FOR AASHTO T 11 Scope A sieve analysis, or 'gradation,' measures distribution of aggregate particle sizes within a given sample. Accurate determination of the amount of material smaller than 75 µm (No. 200) cannot be made using just AASHTO T 27. If quantifying this material is required, use AASHTO T 11 in conjunction with AASHTO T 27.

3.1 SMA - stone matrix asphalt - SMA is a hot mix asphalt consisting of two parts, a coarse aggregate skeleton and an asphalt binder rich mortar. The mixture must have an aggregate skeleton with coarse aggregate-on-coarse aggregate contact (generally referred to as stone-on-stone contact). The coarse aggregate is generally considered

AASHTO defines overloading large sieves as weight retained in excess of 2.5 times the sieve opening in in. (mm), as expressed in gm/in.2 (kg/m2). For fine aggregate, no weight shall be in excess of 4 gm/in.2 (7 kg/m2). Coarse Aggregates. After the material has been sieved, remove each tray, weigh each size, and record each weight to the nearest ...
