Investigation of In-Service Pavement Performance
| 项目名称： | Investigation of In-Service Pavement Performance |
| 摘要： | Wisconsin hot mix asphalt (HMA) pavements across the state experience uneven performance. While most of Wisconsin projects met the design expectations, some of the HMA pavements showed unexpected distresses, including rutting, cracking, and stripping. A comprehensive pavement performance assessment and a forensic evaluation of project performance could lead to improved outcomes for pavement structures. Furthermore, the long-term assessment of the in-service pavement performance could lend insight to mechanisms of failure and to asphalt mix properties that will help achieve increased reliability. These lessons should lead to recommendations to help avoid similar problems in the future. In-place pavements should be investigated to evaluate how different factors have led them to perform as expected or what factors have caused them to underperform. Projects for this investigation will include past WHRP and non-WHRP projects. The evaluation should be completed to determine what factors have caused them to perform well and what factors have caused them to underperform. Parameters to be assessed should include: binder type, polymer modified binder type, warm mix, RAP and RAS, aggregate type, loading and environmental conditions. In addition to conventional projects, some pavements that were constructed with non-conforming materials are occasionally allowed to be left in place. An evaluation of those pavements could further assist in determining how well the specifications are capturing long-term performance. Some of the non-conformance areas to focus on should include air voids, binder content and density. Capturing projects that are at different stages in the expected life cycle should also be done. The objective of the study is to evaluate and analyze the constructed asphalt pavement parameter and the long-term performance of pavement projects in Wisconsin. The objective of the study will be addressed by: (1) Assessing in-service pavements from past conforming and non-conforming pavement lots in Wisconsin Department of Transportation (WisDOT) projects; (2) Evaluating what factors affected the performance of past pavements projects; (3) Suggesting adjustments to Mix Design Specification to increase pavement life; (4) Evaluating WisDOT �Spider� Van data; (5) Impacting the implementation of specification changes. |
