testing purposes. Soil types are commonly classified by grain size, determined by passing the soil through a series of sieves to screen or separate the different grain sizes. [See Figure 3] Soil classification is categorized into 15 groups, a system set up by AASHTO (American Association of State Highway and Transportation Officials).

For density - be aware of the bulking factor for the stockpiled material. Example - Stockpiled Anthracite Coal. Anthracite coal with density 65 lb/ft 3 is stockpiled in a conical pile with diameter 30 ft and height 8 ft. According the diagram above the volume of the pile is approximately 2000 ft 3. The total mass of the pile can be calculated as

Bulking of Sand, Test to Calculate Bulking in Sand ...

Bulking of sand depends on the moisture in the sand. But when the moisture is increased by adding more water, the particles of sand gets packed near each other as the film around the sand particles breaks and the bulking of sand is reduced. Dry sand and the send completely filled with water will have the exact volume.

What is bulking of sand?

Graphical representation of bulking of sand is shown below. When the moisture content of sand is increased by adding more water, the sand particles pack near each other and the amount of bulking of sand is decreased. Thus it helps in determining the actual volume of sand, the dry sand and the sand completely filled with water will have the exact volume.

Filamentous bulking and foaming problems require the identification of the causative filament(s). This information leads to specific remedies, appropriate for the filament(s) involved. Short term control methods are often used to quickly stop a bulking problem. However, the best approach is to investigate the long term control methods suitable ...

adjustable in relation to the upper tumbler. Depending on the type of soil, extra measures may be necessary to promote the emptying of the buckets. From the discharge chute the material slides directly into the barge that is moored alongside the dredger or it is transported to it via conveyor belts. To obtain the most even possible filling of the

Physical Properties of Soils (With Diagram)

This process of soil increasing in volume from its state to a loose state is called swell. Shrinkage, on the other hand, occurs when that same soil is placed back in the one cubic yard hole and is properly compacted. Depending on the soil type, the final volume could be 0.9 cubic yards or 1.1 cubic yards.


In aerated static pile composting, organic waste mixed in a large pile. To aerate the pile, layers of loosely piled bulking agents (e.g., wood chips, shredded newspaper) are added so that air can pass from the bottom to the top of the pile. The piles also can be placed over a network of pipes that deliver air into or draw air out of the pile.

The "physics" of soil physics traditionally assumes that soils have rigid behavior; that means relatively stable relations between their solid and pore volume. In the well-known schematic diagram of the three phase system, the solid phase remains stable while the volumes of water and air vary conversely within pore space (Figure 1). Figure 1.

Stockpile Volumes

Proper soil support of the pipe is critical to the performance of both types of pipe, and proper inspection of pipe installation is essential in obtaining the required support. Inspection for proper soil support involves checking the: 1. Adequacy of soil in trench walls and foundation 2. Type of soil used for bedding, embedment, and backfill 3.

Bulking of Sand – Cause, Tests and Importance

Sand is a granular material composed of finely divided rock and mineral particles. It is defined by size, being finer than gravel and coarser than silt.Sand can also refer to a textural class of soil or soil type; i.e., a soil containing more than 85 percent sand-sized particles by mass.. The composition of sand varies, depending on the local rock sources and conditions, but the most common ...

earthwork calculations (different DOTs use different factors depending on soil type). 3. The shrinkage and swelling factors have a wide range for soils which are typical in the southeastern United States. From the values in this research, typical ranges for general soil types in the this southeastern region of the United States were found to vary.
