2 How Louisiana Obtained Highway Bridge Program Funding for Bridge Preventive Maintenance Projects

3 PUBLIC LAW AUG. 10, 2005 SAFETEA-LU clarified federal funding for systematic preventive maintenance This is important because.

4 FEDERAL FUND ASSISTANCE SAFETEA-LU SEC HIGHWAY BRIDGE PROGRAM (A) Painting. (B) Seismic retrofit. (C) Systematic preventive maintenance (D) Installation of scour countermeasures. (E) Application of calcium magnesium acetate, sodium acetate/formate, or other environmentally acceptable, minimally corrosive anti-icing and de-icing compositions.

5 SPECIAL RULE FOR PREVENTIVE MAINTENANCE A state may carry out a project for a highway bridge without regard to whether the bridge is eligible for replacement or rehabilitation. The benefit of this is..

6 You get to do preventive maintenance work on a bridge in good condition before the bridge becomes deficient. Otherwise, the bridge condition has to deteriorate to a certain level before federal funds are allowed to be spent.

7 Two Significant Eligibility Criteria for Highway Bridge Replacement & Rehabilitation Program Funds: 1. Sufficiency Rating of 80 or less for rehabilitation or less than 50 for replacement Year Rule - Bridge cannot have been rehabbed/reconstructed or new/replaced within the past 10 years, regardless of the source of funding.

8 FHWA s APPROVAL OF LOUISIANA S SYSTEMATIC PROCESS 1. Consulted with FHWA division office 2. Researched other states processes 3. Developed systematic process (criteria based on inspection data, etc.) (grid deck and relief joint replacements were not approved) 4. LA process approved July 2007

9 Does a state have to use PONTIS to begin using federal funding for bridge preventive maintenance work?

10 Louisiana s Bridge Preventive Maintenance section is utilizing federal funds on projects selected using a systematic process based on our NBI inspection data.

13 Deficient Item Joints Substructure Bridge Preventive Maintenance Activity Selection Criteria Bridges with DSS* condition ratings 5 and with adjective joint ratings 7 (all joint types) Bridges with DSS* condition ratings 5 and with adjective substructure element ratings 2 and concrete spall/scale ratings 7 Objective Repair/replace deficient joints to prevent water and chlorides from falling onto substructure elements. Repair/replace substructure deficiencies such as: concrete spall repair on pedestals, bents, caps, piling, piers and columns *DSS = Deck (58) and Superstructure (59) and Substructure (60) items

14 Localized deck repairs, deck sealing, spot painting, bearing repair/replacement, grid deck repairs and localized section replacement. Deficient Item Deck & Superstructure Bridge Preventive Maintenance Activity Selection Criteria Bridges in generally good condition with DSS* condition ratings 5 and with adjective deck or superstructure element ratings 7 Objective Repair the deficient deck or superstructure elements and extend the non-deficient life of the bridge. Bridge Deck Drainage Bridges in generally good condition with DSS ratings 5 and with adjective drainage ratings of 5, 6, or 7 Clean the bridge deck drains to prevent ponding and excessive runoff to bridge joints. *DSS = Deck (58) and Superstructure (59) and Substructure (60) items

15 PREVENTIVE MAINTENANCE VS. REHABILITATION Is the bridge SR < 50? Satisfying this criteria qualifies a bridge for replacement. Do the proposed PM activities on one bridge total more than 30% of the estimated replacement cost? Combinations of PM activities can be programmed using HBP funds. Process under rehab / replacement program.

16 CONDITION RATINGS 6 SATISFACTORY CONDITION structural elements show some minor deterioration 5 FAIR CONDITION all primary structural elements are sound but may have minor section loss, cracking, spalling, or scour 4 POOR CONDITION advanced section loss, deterioration, spalling, or scour

17 ADJECTIVE RATINGS 8 The item is in good condition with no maintenance necessary 7 The item is in fair condition, but requires maintenance 6 The item is performing the function for which it is intended, but requires maintenance 5 The item is still performing the function for which it was intended at a minimum level, but requires maintenance

18 ADJECTIVE RATINGS 4 The item is still performing the function for which it was intended at a minimum level, but requires major rehabilitation 3 The item is still performing the function for which it was intended at a minimum level, but requires replacement 2 The item is not performing the function for which it was intended, requires maintenance 1 The item is not performing the function for which it was intended, and requires major rehabilitation
