Field Durability survey and Evaluation of Drilled Shafts and ACP Piles

The primary objective of the study is to determine if there are significant safety and durability issues for structural concrete structures that may have demonstrated thermal cracking and/or mattressing defects. Understanding if and/or when undesirable consequences occur will lead to the ability to recommend changes in construction practices or material composition (i.e. concrete mix designs) to increase reliability and longevity of future Florida Department of Transportation (FDOT) concrete structures.
