Transite Design Information
(OP)
I would greatly appreciate any engineering information for asbestos-containing TRANSITE pipe. I have a project where we need to cross a buried 24-inch TRANSITE sewer pipe with a heavy traffic load, and I want to compare the pressure against allowable limits.

I am assuming that the utility that owns the pipe has a proper installation. Test boring information in the vicinity of the pipe suggests that the soils are low-blowcount uncontrolled fills to a significant depth.
What I don't have any idea about is the material properties of the Transite material itself, so I don't have a baseline to know when the stresses from the traffic loads (we will be traversing the pipe only twice) are sufficiently reduced, depending on the measures we undertake to spread out the loads.
We will have a 100-ton capacity crane potentially carrying a 80,000 ton load across the alignment of the pipe. Due to the dimensions of the crawler tracks, we already get a pretty good reduction in the ground pressures.
Based on the test boring information that we have, we will likely need to take measures to permit safe transit of the loaded crane on the fill soils anyway. What I would like to determine is how much more to do to protect the pipe from this loading.
Any further information or thoughts are appreciated.

As others have cautioned, this is old, possibly brittle stuff so be very careful.
Did you mean 80,000 tons or 80,000 pounds !?
good luck

Whoops! I did mean 80,000 lb rather than tons. I appreciate the warnings about handling of the asbestos concrete. We will strive mightily to avoid damaging the pipe in the first place!
rwf7437,
I have sent you an email. Many thanks for your generous offer.
BigH,
Bridging the pipe with a purpose-built structure was one of my first thoughts, as well. Naturally, we wnat to keep the cost down, as the need to do this was not entirely forseen.

We ended up excavating trenches parallel to the pipe and pouring plain concrete bents to bridge over using crane mats.
