20191111 Crushed stone often has an angular and jagged edge because of the crushing process. Gravel, on the other hand, typically has a very smooth texture and surface because of the natural weathering and wear of being exposed to running water. Unlike crushed stone, gravel is usually sold and used in its natural state.
2019819 For two-product crushed base course structures, the lower layer is usually more free-draining and coarser (with a max nominal size of 50mm or 75mm). 3.4.2 Select Granular Sub-Base (SGSB) Select Granular Sub-Base (SGSB) material typically consists of a 75mm-minus sand and/or gravel mixture that is either processed (screened and/or

Asphalt grindings contain approximately five to seven percent asphalt, which is used as a binder for the quarry materials (stone, rock, sand, silt) that make up the load-bearing portion of a bituminous concrete surface. The asphalt
6.2.3 Sulphate Soundness. As subbase, capping or fill material, the material is exposed to natural outdoor conditions, potentially including sulphates that may be present in the surrounding soils. It is standard practice to evaluate the resistance of the aggregate to weathering, in the form of sulphate soundness tests.
2022715 For use in trail surfacing, the material should be composed of irregular angular particles that interlock and bind into a firm matrix. The rock particles should range in size from dust to 3/8 inch. Gravel and crusher fines differ from one another in that gravel is screened to remove the fines which contain the natural binders/cements.
2007102 The angle of internal friction of a crushed stone will be directly influenced by type of rock and grain size. Forty-one (41) seems to me possible, but dangerous. I would use a safe 36 degrees unless a direct shear test is performed on a sample. There's at-rest earth pressure and active earth pressure.
201851 This article provides a comprehensive review on the angle of repose of granular materials, which is a key parameter in many engineering and geotechnical applications. It covers the definition, measurement methods, influencing factors, theoretical models, and practical implications of the angle of repose. It also compares the angle of

As an example, let's say your DIY project is a patio, and it calls for the use of crushed stone as a base. If your patio is 20 feet long and 10 feet wide, and you need 6 inches
