Provide safe access to the material for sampling from haul units or stockpiles. Do not use spent metal casting foundry sand, unless the contract expressly allows for its use.

1.1 This test method covers the determination of bulk density (“unit weight”) of aggregate in a compacted or loose condition, and calculated voids between particles in fine, coarse, or mixed aggregates based on the same determination. This test method is applicable to aggregates not exceeding 125 mm [5 in.] in nominal maximum size.

Compaction of Subgrades and Aggregate Base Courses. Construction compaction is the process by which the weight-per-unit volume of soils and aggregates is increased by the use of applied force. This weight-per-unit volume, or density, is measured and compared to a laboratory-determined maximum density of the same material.

Payment by Weight. When payment is by weight, refer to weighing material and mixtures in subsection 109.01 and Section 302 of the Standard Specifications for Construction. Aggregate will be weighed to the nearest 100 pounds (50 kg). Pay weights will be the scale weight of the aggregate unless the moisture content is more than 6 percent.

Oct 10, 2015· Rodded Unit Weight of Coarse Aggregate Purpose Determination of the unit weight of coarse aggregates in a compacted condition. This test method is applicable to aggregates not exceeding 15 cm (6 inches) in nominal size. The unit weight so determined is necessary for the design of a concrete mixture by the absolute value method. Equipment

aggregate surface course applications, compact each layer of aggregate to at least 95 percent of the maximum unit weight, at a moisture content no greater than optimum. Shape the finished surface and layers to within ±½ inch of the crown and grade shown on the plans. If placing aggregate base in a layer no greater than 3 inches, compact using

Asphalt concrete base (ACB), also called asphalt treated base (ATB), is a dense-graded HMA with a larger nominal maximum aggregate size (1 inch) intended for use as a base course or binder course (see Figure 1). In addition to site paving benefits, ACB can be advantageous because it can provide: A waterproof barrier to prevent fines infiltration into the subgrade and pavement structure.

The compacted unit weight of RAP will decrease with increasing unit weight, with maximum dry density values reported to range from 1600 kg/m 3 (100 lb/ft 3) to 2000 kg/m 3 (125 lb/ft 3). (8) California Bearing Ratio (CBR) values for RAP material containing trap rock aggregate have been reported in
