How well are we maintaining our infrastructure?

Quantitative evaluation of the condition of assets

Should be analyzed and used to reallocate resources and funding to meet your asset management goals

Asset Inventory

TDOT uses a condition assessment program called the Maintenance Rating Index (MRI)

Random sample of roadway network

Approximately 6% of roadway miles evaluated each year

7,107 1/10th mile segments assessed in FY 2010

Condition Assessment

Asset Inventory

Evaluates all roadway characteristics monthly

Each characteristic has weighting factor used to generate a score

Pass/Fail based on whether it meets the minimum condition standard

Score from 0 to 100Target score is 90

10% of segments evaluated by third party consultant for quality assurance

In-house scores ~ 90QA scores ~ 82Red trend line should

match up to black line if QA & In-house scores were similar

Red line shift indicates higher In-house scores

Concentration of points with In-House score of 100 & QA score considerably lower is a concern In-House vs. QA

requirementQuantitative evaluation

instead of subjective opinion

Provides for opportunity to find deficiencies that windshield inspection may miss

Data indicates that In-House self-evaluation has lead to elevated scores

May need to consider using impartial third party to perform inspections in the future
