Superpave defines nominal maximum aggregate size as “one sieve size larger than the first sieve to retain more than 10 percent of the material” (Roberts et al, 1996 [1]) Thus, it is important to specify whether “maximum size” or “nominal maximum size” is being referenced

The nominal maximum aggregate size is defined as one sieve size larger than the first sieve to retain more than 10 percent aggregate as shown in the design range specified in Section 21103, Table II-13 of the Road and Bridge Specifications

the aggregate and the alkaline hydroxides derived from the alkalis (Na , it is recommended to control the limit of alkalis in the cement Total 54 26 456 Soundness of Aggregate This is the name given to the ability of aggregate to resist excessive changes in volume as a result of , Nominal Size of Material (mm) Minimum weight ,

Nominal maximum size of aggregate = mm Enter unit weight of coarse aggregate (if unknown, use 1500 to 1900 kg/m 3 for normal weight aggregate) = kg/m 3 Enter fineness modulus of fine aggregate = Enter (from Table above) volume of coarse aggregate per unit volume of concrete = Enter specific gravity (Saturated Surface Dry, SSD) of coarse aggregate ,

Estimate the amount of entrapped air for maximum nominal size of the aggregate from the table 4 Select the water content, for the required workability and maximum size of aggregates (for aggregates in saturated surface dry condition) from table 5

As maximum size of coarse aggregate reduces, surface area of coarse aggregate increas Higher the surface area, greater is the water demand to coat the particles and generate workability Smaller maximum size of coarse aggregate will require greater fine aggregate content to coat particles and maintain cohesiveness of concrete mix

Step 2, Choice of maximum aggregate size: If the maximum aggregate size is not specified, determine the maximum aggregate size for the mix Take into consideration

The effect of maximum aggregate size on size effect in compressive strength is negligible for mass concrete with large aggregate size Acknowledgments The writers are grateful for the generous support provided by Sharif University of Technology

The nominal maximum size of the aggregate is defined as the smallest sieve opening through which the entire sample of the aggregate will pass According to the Coarse Aggregate Gradation Chart in Item 421 of TxDOT’s 2004 Standard Specifications for Construction and

Nominal Maximum Aggregate Size for WisDOT Specification R esearch in the area of Superpave mix design has resulted in expansion of the nominal maximum aggregate size (NMAS) mix designs available and has

In manufacturing, a nominal size or trade size is a size "in name only" used for identification The nominal size may not match any dimension of the product, but within the domain of that product the nominal size may correspond to a large number of highly standardized dimensions and toleranc

The effects of aggregate type, size, and content on the behavior of normal and high-strength concrete, and the relationships between compressive strength, flexural strength, and fracture energy are discussed

Minimum lift thickness should be at least 3 times the nominal maximum aggregate size to ensure aggregate can align themselves during compaction to achieve required density and also to ensure mix is impermeable Therefore, the desired lift thickness can direct the decision on nominal aggregate size to use

The grading of coarse aggregate may be varied through wider limits than that of fine aggregates, since it does not affect the workability, uniformity and finishing qualities of concrete mix As per IS-383 the grading limit of coarse aggregate, both for single size as well as graded should be as per the table given below

The aggregate gradation used in Superpave hot mix asphalt (HMA) mix design is required to be within control points at 0075 mm (No 200), 236 mm (No 8), and nominal maximum aggregate size
