sand compaction grinding
MnDOT GRADING & BASE MANUAL
Soil selection is one of the most important functions of the grading inspector. The grade is the foundation for the roadway. The materials selected as a foundation should be the best available. For most grading projects, a soil survey has been made prior to design to determine what kinds of soil will be uncovered at or near grade line.

Soil compaction | UMN Extension
What is compaction? Soil compaction occurs when soil particles are pressed together, reducing pore space between them (Figure 1). Heavily compacted soils contain few large pores, less total pore volume and, consequently, a greater density. A compacted soil has a reduced rate of both water infiltration and drainage. This happens because large pores more effectively move water downward through ...

Compaction of soil in construction
Compaction is a process that involves an increase in soil density or unit weight, accompanied by a decrease in air volume. There is usually no change in water content. The degree of compaction is measured by the dry unit weight and depends on the water content and compactive effort (hammer weight, impact number, roller weight, number of steps).

Swell Factors for Various Soils - ProjectEngineer
Swell Factors for Various Soils. A cubic yard of earth measured in its natural position swells to more than a cubic yard after it is excavated. This occurs because of an increase in voids. Swell is expressed as a percentage of natural volume, for example, if 10 yd 3 in the ground becomes 13 yd 3 after excavation, the swell factor is 30%.

The Causes and Effects of Soil Compaction - SoilErosion
Soil compaction is most often seen on farmland and areas where land is cultivated as heavy machinery passing over land presses soil into itself. When people use heavy machinery, 70 to 80% of soil compaction takes place on the first pass. Yet the compression of soil has its benefits when used to the right advantage.

Having a good mix of large and fine particles is recommended for successful compaction. Place the sub base in 4" to 8" lifts if possible, but be aware the compaction force of the machine may require you to adjust this. As a good rule of thumb, adjust your lift height in the ratio of 1" of material for every 1000lbs of compaction force.
