Sep 20, 2007 . These imported fills may include granular materials such as sand, gravel, or crushed stone. These high-strength and permeable materials offer low compressibility, which is ideal for a slab-support system. “Six inches of well-graded gravel or crushed stone material properly compacted will give good results,”.

Building Crusher Fines Trails, Finely crushed compacted rock is a .

Finally, the trail surface is re-compacted with rollers or vibratory compactors. During the compaction process, the crusher fines should have some moisture to help "cement" the material when it dries. To ensure adequate moisture, fines may be sprayed with water during the crushing process to give them 4 to 5% water.

'Self-Compacting' Soils - Underground Construction

Recent large scale compression tests on crushed rock and gravel have demonstrated that the stiffness (e.g. modulus of deformation, constrained modulus) can easily double when the density increases from 85 to 95 percent compaction (Gemperline and Gemperline 2011). This increased soil stiffness reduces the settlement.
