Substation Grounding: Role of Crushed Rock – Voltage ...

Since the crushed stone has higher resistivity than surface soil, most of the ground current remains confined in the surface soil below the crushed stone. Since there is very little current in the layer with crushed rock, the surface voltage (step, touch potential) will be negligible. This is the basic idea behind using crushed rock in electric ...

Crushed Stone - an overview | ScienceDirect Topics

Tests have also shown that steel slag is an equally good substitute for gravel or crushed stone aggregate in both stabilised cement and unbound base layers. Properties of a cement-stabilised mixture of slag, natural crushed stone, and 0.7% and 2% of cement (Class 42.5 N) meet the compressive strength criteria set by Croatian standards [27].

and testing because the cost is too high.This claim can be countered with the argument that if several thousand tons of aggregate are going to be purchased or crushed, is it not wise to invest a few hundred dollars in testing the material to insure that the right aggregate is used? It is a good practice to test the aggregate before placing it

The crushed stone industry is important in the economy of Arkansas. In spite of a comparatively low population, Arkansas ranked 19th in the nation in production of crushed stone in 1996 (U.S. Geological Survey, 1997a). In the same year, crushed stone accounted for nearly 40% of Arkansas' non-fuel mineral production value, with a total raw ...

Proctor testing of 3/4" clean stone - Soil testing ...

I have not seen a procter for crushed stone. Typically the stone is placed in 12-18" lifts and tamped once or twice. The stone is so much stronger than the soil and is unaffected by moisture content that lab or insitu density testing is not done. We use it in freezing weather to backfill when soil would be impossible.
