Crushed stone: If you hear the generic “crushed stone” term, it usually refers to stone that has a mixture of stone dust in it. This type of stone is best used for a base when heavy compaction is needed. As a result, it is typically used for the base of concrete and paving projects, foundations of structures, and driveway bases.

Crushed stone is a commonly used aggregate for backfill material in engineering, and its compaction behavior under load needs to be well understood. In this work, a series of compaction tests were carried out on the same batch of crushed stone samples with the same gradation.

Crushed salt will be used for backfilling of cavities and sealing measures in drifts and shafts due to its favourable properties and its easy availability (mined-off material). The creep of the rock salt leads to crushed salt compaction with time. Thereby, the crushed salts’ porosity is reduced from the initial porosity of 30%–40%

Whenever compaction of pavement structure is presented, it is always a good idea to identify CLEARLY (a) the type of material (i.e., crushed stone aggregate, river gravel, etc) (b) the compaction method used (i.e., standard or modified Proctor (light or heavy tamping for our British friends). This establishes facts that anyone making a reply will want to know
Around trees compaction is not so good, but not putting a trail next to trees is nearly impossible in most of the country, and provides a nice user experience. One solution is to add soil over roots where trees are crossed by trails in their drip line. Another option is to not deduff in this area and/or add more mulch to protect roots, although mulch is typically not an ideal trail tread

Crusher run also referred to as quarry process stone, is a type of gravel that consists of coarse aggregate (crushed gravel) and fine aggregate (limestone dust). The crushed stone particles are typically ¾-inches in diameter, while stone dust particles are usually 1/8-inches wide or smaller. Crusher run is commonly used in driveways as a base material, but can also be laid on the top layer of

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.
