Backfilling Pipe Trenches Backfilling Pipe Trenches

Backfilling Pipe Trenches

The ideal material for pipe trench backfill under pavements is crushed limestone with rock ranging from fines all the way up to 21/2″. Properly graded crushed limestone has just the right balance of aggregate sizes and square shaped aggregate to ensure interlocking of the particles which will ultimately maximize density, strength, and resist future settlement.

Permeability of Granular Subbase Materials

 · 1. The crushed concrete that is used as a subbase material has a relatively low permeability compared to many other materials used by other states. 2. Further research and tests are needed to find the necessary parameters for crushed concrete to make sure it is providing its optimum drainage and preventing premature damage of the pavement. 3.
