Bridge Element Deterioration for Mid-West StatesTPF-5(432)

Collaboration of AASHTO TSP-2 Members

Chief of Structures Development

Current Need

• It is necessary for DOTs to have insight to rates of deterioration to be able to anticipate future condition and work actions to manage their bridge assets.

• Deterioration rates and forecasting future condition provides the ability to identify, prioritize, plan, budget, and implement work in a systematic manner.

Element Deterioration for Mid-West States 2

Objective of the Study

• 12 mid-west DOTs pool resources and historic mid-west DOT bridge datarelated to:

Historic design/construction details.

Operation practices

Maintenance activities

Element, Defect, NBI, and related Inspection data

Element Deterioration for Mid-West States 3

Objective of the Study

• Develop deterioration curves that are specific and focused to address key transition points in a life of bridge structures so that accurate determination of timing of work actions is possible

• This effort will pool data and create results that will improve accuracy of various bridge management and asset management applications that the member DOTs use (AASHTO BrM, Agile Assets, and homegrown).

Element Deterioration for Mid-West States 4

Deliverables

• Analyze DOT Element, and Defect, and NBI information to develop deterioration curves.

• Produce first generation of select deterioration curves with documented methodology to update these curves and add additional element curves.

• Correlate available NDE to historic element information (past NDT results) with actual field work actions.

Task 7 – Develop Tier 2 Deterioration Curves

• 1 – Element-Level Deterioration Curves for Wearing Surfaces• 2 – Element-Level Deterioration Curves for Deck Joints• 3 – Deterioration Curves for Defect Development and Progression• 4 – Deterioration Curves for Paint System Effectiveness• 5 – Defect Deterioration Curves for Steel Girder Corrosion• 6 – Element-Level Deterioration Curves for Substructure Elements in

Harsh Environments

Presentation Title 9

Task 8 – Develop Tier 3 Inputs

• 1 – Identify Agency-Defined Elements Identify any agency-defined elements (ADE) that would be of use for other

Midwest DOTs to consider adopting.

• 2 – Determine NDE Translation Nondestructive Evaluation (NDE) Midwest DOTs have and how it is used that

translates into information on element-level defects

• 3 – Provide Summary of Policy, Guidance, and Practices practices that Midwest DOTs employ to relate NDE results to defect reporting

(to describe delamination and deterioration)
