A highway culvert is a drainage facility that allows water to flow under the road without causing any traffic disruption. Corrugated and spiral steel pipe are popular for culverts because they can be installed quickly, have long life, are low in cost, and require little maintenance. With corrugated steel pipe, the seam strength must be adequate to withstand the ring-compression thrust from the total load supported by the pipe. This thrust C, lb/ft (N/m), of structure is
C=(LL+DL)S/2
where
LL= live-load pressure, lb/ft2 (N/m2)
DL= dead-load pressure, lb/ft2 (N/m2)
S= span (or diameter), ft (m)
The pipe should have sufficient handling and installation strength so as to withstand stresses due to shipping and placing of the pipe in the desired position. The handling strength is measured by a flexibility factor which is:
FF=D2/EI
where
D =pipe diameter or maximum span, in (mm)
E= modulus of elasticity of the pipe material, lb/in2
(MPa)
I =moment of inertia per unit length of cross section of the pipe wall, in4/in (mm4/mm)

its very useful
It is a very wonderful resource
Very nice and helpful.
can i ask what are the components of roads and highway??
Is the culverts are directly connected with the pavement?
or there is a gap b/w the r.c.c culverts and pavement.
Yes gap is required for Expansion & contraction due to variation in
atmosheric temperature. ggenerially 19mm to 25 mm gap is kept and
filled with bituminious pad expansion joint. If these are not
Provided the crack will appear due to temp stress.

I want to the various types of road construction reports with their definitions and time of required in the construction process
i want to know about optical fiber used in rigid pavement?????
I want 2 know how a curve can be determined in road during surveying.
hi, im a civil engineering student. i want to learn more about on how to control flooding. bec. philippines are always suffering from flooding and were not well educated about this matter. give me an idea on how will i start it. thanks.
this s my favorite field…so can i get sum information to study dis branch..?
me doing civil engineering in 3rd year…so pls give me sum information regarding dis field pls as soon as possible..
