Iron Casting Alternate Designs

November 29, 2007


The following alternate castings are approved for use as alternates to the castings shown on the ODOT standard construction drawings as specifically noted in the table below.

All castings must meet the requirements of ODOT  711.14 and AASHTO M306 and accordingly, each shipment must be accompanied by a foundry certification as described in section 10 of AASHTO M306. In addition, test bars will continue to need to be pre-approved for each casting date. Click HERE to view a list of pre-approved cast iron test bar dates.
