The technical results of this research will be: the observation of changes in composite and structural properties for an actual in-service composite structure, the use of non-destructive evaluation to identify damage modes, both in the laboratory and in the field, the devlopment of an understanding of the kinetics of degradation processes that can serve as the basis for accelerated testing, and the extension of the MRlife(a well-established durability code)durability model to polymer composite bridge deck applications.

这项研究的技术成果将是：观察实际在役复合材料结构的复合材料和结构性能的变化，在实验室和现场使用无损评估来识别损伤模式，发展对退化过程动力学的了解，作为加速测试的基础，并将MRLife(公认的耐久性规范)耐久性模型扩展到聚合物复合材料桥面应用。
