There is however some basic information concerning the structural design and support etc. of uninsulated ductile iron pipe on supports and bridge crossings available from DIPRA at dipra.org (and also some in AWWA Manual M41 (Manual of Water Supply Practices Ductile Iron Pipe and Fittings).

The normal insulation for an application like you describe is a fiberglass insulation 2" thick. The fiberglass insulation is protected with jacketing. The jacketing is either plastic, aluminum, or stainless steel. Stainless straps are used to hold the jacketing on.
What you have to consider is the design temperature, and possible exposure to road salt (damage to jacketing).
