Grading of Coarse Aggregate. The grading of aggregate is its classification according to the average size of the particles. It is important that the grading is kept constant for concrete batches. The aggregate particles need to be of a consistent size for an even grading. Similar shaped coarse aggregates make the concrete more cohesive and uniform. Uniformly blend the aggregate during crushing operations or mix in a plant. The plant shall blend and mix the materials to meet the specifications and to secure the proper moisture content for compaction. 2083.4 PLACING. Place aggregate base material on the prepared underlying course and compact in layers of the thickness shown on the Plans.

AASHTO 1 Stone Size. Aashto 1 has a top rock size of 2 to 4-inches. While it is too bulky to be effectively used for surfacing, this grade of crushed stone is an excellent material for subgrade stabilization. AASHTO 1 is the largest crushed stone variety offered by Union Quarries. maximum size of 19-38 mm (0.75-1.5 in). The compacted mix has a void rate of about 30 percent. MIX CHARACTERISTICS Aggregates The aggregates used were crushed stone from local quarries, mostly granitic, and some basaltic rock. Four grading specifications were used and tested for the binder course 1.

Road Aggregate 101 Nominal maximum and/or minimum sized stone in mix The nominal size distribution of an aggregate specification is defined as the range of sieve openings through which 100% of the aggregate can pass. Road Aggregate 101 Gradation or distribution of different sized stones Open graded aggregate vs. well graded aggregate. Grade 8 Gravel . AASHTO 8 is a large grade of crushed stone. Like AASHTO 1, 3, and 57, it is a clean material that will not compact. However, the top size of AASHTO 8 aggregate is significantly smaller, making it ideal for different applications within the construction industry.

Maximum size.The smallest sieve through which 100 percent of the aggregate sample particles pass. Superpave defines the maximum aggregate size as one sieve larger than the nominal maximum size (Roberts et al., 1996 1). Nominal maximum size.The largest sieve that retains some of the aggregate particles but generally not more than 10 percent by weight. The grading and grading limits are usually expressed as the percentage of material passing each sieve. Fig. 5-6 shows these limits for fine aggregate and for one size of coarse aggregate. There are several reasons for specifying grading limits and nominal maximum aggregate size they affect relative. 82. Design and Control of Concrete Mixtures ...
