Aggregate Sizes Quality in California

May 04, 2011 · Aggregate Sizes Today I thought I''d talk about the different size classifiions of aggregates. There are infinite size distributions of aggregates. These sizes can either be referred to in metric or English units. At one time Caltrans tried to switch over to metric units but have since switched back to English units.

Effects of Aggregate Size, Shape, and Surface Texture on

face area of the aggregate are important factors in fixing the asphalt requirement. Surface area is a function of aggregate size and size range. The larger the aggregate size, the smaller is the surface area for a given weight or volume of aggregate. In densegraded aggregates, the major portion of the surface area occurs in the fine ag

The effect of maximum size of aggregate on concrete strength

Similarly, higher flexural strength is obtained at a given w/cm with smaller nominal maximum size aggregate. Data from compression tests of concrete containing very large aggregates, 100 mm (4 in.) and over, are conflicting because of limitations in the size of the test specimens and testing machines.

Permeability vs. Aggregate Size and Lift Thickness

Nominal maximum aggregate size (NMAS). Mixes with larger nominal maximum aggregate sizes tend to have larger sized voids, which are more likely to be interconnected. Therefore, at the same air void level, mixes having larger nominal maximum aggregate sizes have more potential for high permeability than mixes of smaller nominal maximum aggregate
