832 SECTION 714 CONCRETE AND PLASTIC PIPE
714.1: Blank
714.2 -REINFORCED CONCRETE CULVERT, STORM DRAIN AND SEWER PIPE : This pipe shall conform to the requirements of AASHTO M 170 or ASTM C76, AASHTO R 73, and MP 714.03.30. Class III, IV, and V reinforced concrete pipe are to be used.
714.2.1 –Special Design: When reinforced concrete pipe pay item includes Special Design designation, the following shall apply per designation in the plans.
714.2.1.1 -Structural: High fill cover heights, minimal cover heights, or excessive loads, which require special reinforcing and design of reinforced concrete pipe.
714.2.1.2 -Cement Content: Corrosive environments, which require special concrete mix to improve the sulfate resistance. Table 714.2.1.2 illustrates the material requirements for a gi ven sulfate concentration.
