| 摘要： | The focus of this report is to provide a state-of-the-art review of the research and developments in the area of field tests (both destructive and non-destructive) that can be used to ensure compliance between the properties of constructed pavements and the material properties assumed in design. This effort constituted a utility assessment of the potential of different testing methodologies for concrete pavement systems capable of being incorporated into future TxDOT testing regimens that are suitable for mechanistic design applications. In light of this emphasis, key parameters that are used or could be used in design which have a relationship to performance were identified. In conjunction with this emphasis, test procedures which involved parameters that tie construction quality to design were of particular interest, especially if they displayed a certain amount of practicality and repeatability. Also, tests that represented a direct measurement rather than an indirect measurement of a parameter were preferred in addition to those that made measurements in-place and could make use of department equipment where possible. In this regard, the recommendations from this project were partially based on the current TxDOT Cy7QA specification developments to ensure continuity since some of the key parameters were previously identified as part of the (JC/QA effort. Although most of the key parameters pertained to the concrete surface layer (including bonded concrete overlays), parameters of each layer in a concrete pavement structure were considered in the report. |
