Chapter 4. Recommendations For Needed Research
The objective of task E was to develop specific recommendations for needed research where existing research was not sufficient to allow development of proposed revisions to the AASHTO specifications. During the review of the AASHTO specifications, many areas of needed research were identified. For some areas, the amount of needed research was minimal, while major research projects would be needed for others. Many of the areas requiring a small amount of research of a similar nature were combined into a single, more substantial research project. At the same time, it was recognized that the following NCHRP projects were underway or in the process of development and will address some of the research needs identified in this project:
Consequently, none of the research problem statements developed on this project overlap the four NCHRP projects listed above.
The end result of the above-mentioned process was a series of 10 proposed research projects. Six of the projects have a strong emphasis on concrete materials technology, while four relate primarily to structural design.
The following six research projects have a strong emphasis on concrete materials technology:
The following four projects relate to structural design requirements:
For each of these projects, a research problem statement using the NCHRP format is included in appendix F.
