Inspection and QA/QC for ABC Projects
| 项目名称： | Inspection and QA/QC for ABC Projects |
| 摘要： | The application of accelerated bridge construction (ABC) techniques has significantly increased in recent history as familiarity and confidence in the construction methods have grown. While the main benefit of ABC projects is a reduction in closure times and associated user costs, an added benefit is the increased quality of prefabricated bridge elements. However, these elements can only perform as expected if the quality and performance of the cast-in-place, field constructed joints/connections are of the same caliber. There is a general lack of existing research and knowledge regarding inspection of joint quality and performance prior to opening to traffic, despite the critical importance of these bridge elements. The proposed project will evaluate the capabilities of existing nondestructive testing technologies that could be used for inspection and quality assurance/quality control (QA/QC) purposes. The applicability of these technologies could then be considered for ABC purposes, such as the determination of bond and joint strength between pre-formed deck panels and the cast-in-place joint strips. The applications to be explored will be based upon the literature review findings and the limitations associated with each method. |
