Inquiry (采购产品): Culvert Information I am reviewing plans for a river crossing at a project site in Michigan. The contractor is proposing 48" CMP pipe with only 1 foot of crushed stone cover to support a 90 ton truck. Is that enough cover? Is there a resource that you may be able to shoot me towards in order to better determine this? The AASHTO manuals I have do not account for loads this large. Thank you for your time. **** Hidden Message ***** Scott Fonte 13214 Company: BBL Engineers, Inc E-mail: sfonte@bbl-inc.com **** Hidden Message ***** sfonte@bbl-inc.com
