Typical Backfill Structure
Alternate Backfill Methods – Shaped Trench Bottoms
• Shaped trench bottoms may be used in lieu of the standard trench detail shown in Figure 1, provided a free
flowing pea gravel or small rock chips are used to fill in the resultant void areas. Pea gravel or small chips
shall be clean material passing a 3/8 inch (9.5mm) sieve meeting the class I, II, or III requirements of ASTM
D 2321. This applies only
to those insitu soil conditions where the native soil can be cut to a stable shaped
trench. Line and grade may be affected due to the use of a modified trench bottom which may affect the pipe
hydraulics.
