Background/Research Needs
NCDOT uses its PMS to
conduct funding and performance analyses
Key components of PMS:
Deterioration models Cost-Benefit Analysis (CBA) Decision trees
Research needs:
Accuracy and suitability of
deterioration models
Appropriate weight
factors/values for CBA
Appropriate trigger points on
decision trees

SLIDE 4
Research Objectives
Check and validate accuracy and suitability of existing
deterioration models, and to develop and validate new models if necessary
Select appropriate types of weight factors and their
values for cost-benefit analysis
Review trigger points on treatment selection decision
trees
Develop a clear and concise method to evaluate and
update deterioration models and weight factors
SLIDE 5
Research Methodology – Deterioration Models
SLIDE 6
Research Methodology – Deterioration Models
Field data collection
SLIDE 7
Research Methodology – Cost Benefit Analysis
Important to assure appropriate weight factors be
chosen to meet departmental condition goals & priorities
Obtain expert opinions & executive level input Select prominent types of weight factors & weight
values
SLIDE 8
Research Methodology – Decision Trees
Important to consider any new decision variables
when selecting models and grouping pavements
Obtain input from NCDOT Review trigger points to assure appropriate
treatment selection
