For reasonably selecting graded crushed stone materials, material selection standard is proposed for each traffic level of municipal roads according to the local common material properties in.
The strength ratio is to some extent dependent on the material type. however, at a low strength level appropriate to cement-treated materials, the direct tensile strength is typically about one-tenth of the ucs. similar results were also reported for cement treated crushed stone by balbo and it may be expressed as 4 f dt 0.10 f.
Some of the important properties of the steel slag and crushed limestone aggregates are summarized in table 1. the physical properties of steel slag aggregates are superior to those of crushed limestone aggregates. the major difference between the steel slag and crushed limestone aggregate is the bulk specific.

For use as base or cushion material for a paved road. there are two major differences between surface gravel and base cushion material. good gravel for section iii surface gravel section iii surface gravel 39 base courses will generally have larger top-sized stone and a very small per-centage of clay or fine.
Deviation. by examining the influence of mechanical rock properties on particle size of crushed material it was found that the increase in compressive strength increased the proportion of larger particles while other properties showed no effect. keywords mining, crushing, physical and mechanical properties of rocks, energy, crushed stone,.
A stone surround at a fireplace or cooktop, between the heat source and a flammable outer material, is an example where the conductivity of the stone should be carefully determined before selection. another common application is a heated pavement system, where the thermal conductivity of the stone becomes a factor in determining the system.
