| Abstract: | In Test Methods Tex-113-E and Tex-114-E, the Texas Department of Transportation (TxDOT) employs an impact hammer method of sample compaction for laboratory preparation of road base and subgrade materials for testing. In this third and final report documenting efforts to improve the relationship between laboratory material compaction and field construction, Texas Transportation Institute (TTI) researchers present results from efforts to identify whether TxDOT should require Modified Proctor compaction for bases, and whether TxDOT should modify its existing laboratory compaction methods to improve the state-of-the-art. Efforts to evaluate whether a shift to Modified Proctor was warranted proved unfruitful due primarily to a lack of interest and lack of participation from field offices. |
