 To obtain satisfactory results with precast slope blocks, a uniform and properly compacted sand grade is necessary.  The front slopes are most easily compacted when this fill is placed before erection of the structural steel or prestressed beams.  If the compaction operations are left until after the beams are in place, special efforts and equipment are often necessary to obtain proper density.  Backfill placed in the header trenches will require compaction and density tests before placing blocks.

 Toe headers should be analyzed to ensure that the area will be properly drained.  When toe headers at grade separation are not placed on the front of the columns, there is a possibility of trapping surface water between columns and keeping the entire shoulder saturated for long periods.  A positive system to maintain correct grades should be used on header forms.  This may be accomplished by use of a cant strip or other suitable means, but final grades should not be left to the ability of the finisher to hand float.

 Material considered should be pounded with a hammer to check its soundness.  If it does not ring under a hammer blow and breaks up easily, it is probably unsatisfactory.  Minimum dimensions are taken from [http://mdotcf.state.mi.us/public/specbook/files/2012/916%20Erosion%20Control%20Matls.pdf Section 916] of the Standard Specifications for Construction.
