Evaluation of WisDOT Quality Management Program (QMP) Activities and Impacts on Pavement Performance

A majority of state highway agencies have been engaged in Quality Management Programs (QMP) for a minimum of 10 years with current mix design methodologies (i.e. Superpave mix designs and use of the gyratory compactor). Most QMP testing protocols and resultant data are being applied primarily towards materials acceptance programs and as a single/independent parameter expected to predict or explain future performance. There are multiple factors contributing to pavement performance and any ensuing distress. The factors can be material related, construction related, traffic related, or even involving interdependency between distresses. Studies have not been conducted to evaluate or confirm the significance of QMP acceptance limits and their possible impact on pavement performance. Current tolerance limits were established based on individual American Association of State Highway and Transportation Officials (AASHTO) test procedures’ related precision and bias statements and local materials round-robin results. In order to prepare for migration to performance based/related specifications, and a new era of ME-Pavement Design, the current state of practice needs to be captured and enhanced. This will allow the department to consider only performance based/related factors in future studies leading to quantifiable and beneficial specification improvements. In addition, the amount of time and effort spent in attaining and storing the QMP data is not proportional to their subsequent use either by the department or the paving industry. There is a need to expand the use of this data and directly relate it to other measurable components contributing to the eventual pavement service life. Subsequently there’s an equal need to track and connect existing pavement conditions with production Quality Control data submitted during construction, and ensuing field in-situ performance data collected by highway agencies over a given service life. Given the complexity of this study, it will focus on a small set of roadways to establish trends and “proof of concept”. Depending on the success of this phase, subsequent phases could be considered during implementation activities. The main objective of this study is to evaluate the current QMP, its current measures, required frequencies and subsequent trends for impacts on ultimate pavement performance. Additionally the study will assess the effectiveness of a recent specification change that was intended to increase the amount of asphaltic binder in the mixture in an effort to enhance the hot mix asphalt (HMA) pavement performance. The research team has identified that the establishment of a systematic process of geographically relating the multiple Wisconsin Department of Transportation (WisDOT) “pavement” databases together is crucial to the development of the study’s analysis database as well as future studies that utilize data from multiple WisDOT “pavement” databases. The research team will fully document the systematic process of geographically relating the multiple WisDOT “pavement” databases that are used.
