Guidelines for Informing Decisionmaking to Affect Pavement Performance Measures: Final Report

FOREWORD

The 2012 Moving Ahead for Progress in the 21st Century Act (MAP-21) required performance measures to be established for the Interstate Highway System (IHS). The succeeding bill, the Fixing America’s Surface Transportation Act, maintained support of the performance management elements established under MAP-21. Subsequently, the Federal Highway Administration (FHWA) issued a Notice of Proposed Rulemaking (NPRM) to establish performance measures to assess the condition of the pavements on the IHS and the National Highway System (NHS) as follows: percentage of pavements on the IHS in good and poor condition and percentage of pavements on the NHS (excluding the IHS) in good and poor condition.

The research study that led to the guidelines contained in this report was intended to validate the proposed pavement performance measures established by the NPRM and to demonstrate their use within asset management. The findings of the validation suggest that the performance measures established by the NPRM and ultimately required by the issuance of the Final Rule by FHWA are appropriate, as all the metrics have an effect on overall condition and performance measures. As a result, guidelines for informing decisionmaking to affect pavement performance measures were developed, and they are presented in this report. The objective of these guidelines is to provide information and guidance to highway agencies on the following key pavement decisionmaking issues: method to identify which condition metric is driving the performance measure, temporal effects on performance measures, and effects of maintenance and rehabilitation treatments on performance measures.

16. Abstract
The Federal Highway Administration (FHWA) issued a Notice of Proposed Rulemaking to establish performance measures for the Interstate Highway System (IHS) and the National Highway System (NHS) to assess the condition of the pavement on the IHS and NHS. The performance measures, as proposed by FHWA, to assess the condition of the pavement are based on the percentage of pavements on both the IHS and NHS (excluding the IHS) in good and poor condition. The condition of the pavements is to be determined based on the following metrics: International Roughness Index, cracking percent, rutting, and faulting. The overall objective of the research study that led to the guidelines contained in this report was to validate the proposed pavement performance measures and to demonstrate their use within asset management; this validation study is documented in a companion report. Guidelines for informing decisionmaking to affect pavement performance measures were developed based on the findings from the validation study. The goal of the guidelines is to illustrate to agencies potential strategies to move the overall condition from poor to fair to good. In meeting this goal, the guidelines will enable highway agencies to address critical questions such as the following: What are the drivers of the performance measures? What are the effects of maintenance and rehabilitation treatments on condition metrics and overall condition?
