| The
strength of concrete pipe is designed by the engineer,
built into the pipe at the plant and delivered on
the truck ready to install.
90%
of the structural strength required for a successful
installation is provided by the concrete pipe.
Only 10% is dependent upon the soil backfill placed
by the contractor.
Concrete
pipe requires compacted bedding material only
to the springline (halfway) of the pipe.
A
wide variety of on-site bedding and backfill material
is permissible for RCP (AASHTO spec #17 &
27). No need to import expensive granular
material.
Concrete
pipe has different pipe strength (classes) for
different diameters and applications.
Concrete
compressive strengths are a minimum 4000 psi to
as high as 6000+. With tensile strength
65,000+ psi.
