... 60 A P P E N D I X B Responses from the State DOT Survey 1. Does your agency have a straightedge or a rolling straightedge-based criterion for checking the surface finish of a newly placed concrete bridge deck after the concrete has hardened?
From page 61...
... Responses from the State DOT Survey 61   3. What is the length of straightedge or wheel spacing of the rolling straightedge that is used?
From page 62...
... 62 Practices for Ensuring the Smoothness of Concrete Bridge Decks 5. Does your agency have a specification for new concrete bridge surfaces that is based either on Profile Index or International Roughness Index (IRI)
From page 63...
... Responses from the State DOT Survey 63   • Ohio DOT: A bridge encounter is defined as 25 ft. of pavement on either side of the structure and everything in between (i.e., deck and approach slabs)
From page 64...
... 64 Practices for Ensuring the Smoothness of Concrete Bridge Decks 9. Does the concrete bridge deck need to meet a minimum length in order for the smoothness specification to be applied?
From page 65...
... Responses from the State DOT Survey 65   Comment: • Mississippi DOT and Florida DOT: DOT personnel monitor the data collected by the contractor.
From page 66...
... 66 Practices for Ensuring the Smoothness of Concrete Bridge Decks 13. Are negative or positive pay adjustments applied based on the obtained smoothness?
From page 67...

From page 68...
... 68 Practices for Ensuring the Smoothness of Concrete Bridge Decks 18. What is the threshold for Profile Index (PI)
From page 69...
... Responses from the State DOT Survey 69   20. If the index used to evaluate smoothness is IRI/HRI, what is the mean IRI/HRI of the evaluated section (e.g., 0.1-mile length, entire bridge etc.
From page 70...
... 70 Practices for Ensuring the Smoothness of Concrete Bridge Decks 22. Is the DOT's smoothness specification available on the web?
From page 71...
... Responses from the State DOT Survey 71   23. This question pertains to the DOT's Pavement Management System/Bridge Management System.
From page 72...
... 72 Practices for Ensuring the Smoothness of Concrete Bridge Decks 25. Does the DOT use the roughness data of bridges stored in the Pavement Management System/Bridge Management System to evaluate roughness progression of bridge decks?
From page 73...
... Responses from the State DOT Survey 73   28. What type of maintenance activities or rehabilitation activities are typically performed on bridges to maintain smoothness?
From page 74...
... 74 Practices for Ensuring the Smoothness of Concrete Bridge Decks • New York: Partial depth repairs are performed as maintenance. • Ohio DOT: Ohio DOT has been doing in-house and contractor work to repair the ride due to settled approach slabs and approach pavements.
From page 75...
... Responses from the State DOT Survey 75   used in Connecticut and therefore cannot be considered standard practice. Connecticut DOT does do smoothness testing for asphalt concrete on roadways and imposes incentives/disincentives to contractors through construction contracts that does not include bridges.
