Development and Validation of Pavement Deterioration Models and Analysis Weight Factors for the NCDOT Pavement Management System Project Kickoff Meeting May 13, 2011 UNC-Charlotte Research Team: Don Chen, Ph.D. Tara Cavalline, P.E. Vincent Ogunro, Ph.D. Darren Thompson

Agenda  Background/Research Needs  Research Objectives  Methodology  Proposed Work Schedule  Resources from NCDOT

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 http://www.ncdot.org/doh/pmu/organization/PMS.html decision trees

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

Research Methodology – Deterioration Models

Research Methodology – Deterioration Models  Field data collection

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

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

Proposed Work Schedule

Resources from NCDOT  Access to pavement distress data  Assistance with roadway identification/selection  Information about Cost-Benefit Analysis and Decision Trees  Pavement condition survey training  Access to selected roadway sections and traffic control
