5 Project Title: Optimum Air Content Range (Plastic and Hardened) for TDOT Class D PCC Activation Amount: $4, Agency: Tennessee Department of Transportation Co-PI - Benjamin Mohr, Civil and Environmental Engineering PI - L. K. Crouch, Civil and Environmental Engineering Senior Personnel - Daniel Badoe, Civil and Environmental Engineering Senior Personnel - Jane Liu, Civil and Environmental Engineering Support Personnel - Anthony Greenway, Energy Center Support Personnel - Jeffrey Holmes, Civil and Environmental Engineering Some federal sources have suggested that a higher air content than currently specified in TDOT bridge deck concrete would improve the durability of bridge decks. However, some Tennessee concrete producers have expressed concern about the effects of the higher air content on obtaining the specified compressive strength of 4000-psi at 28 days. Further, it has been suggested that the measured plastic and hardened air contents may differ significantly. A study is needed to determine the possible advantages and disadvantages of various air contents in TDOT bridge deck concrete as wells as the agreement between plastic and hardened air content determinations. The study needs to be conducted using typical Tennessee materials and a typical TDOT bridge deck mixture design over a wide range of air contents to be relevant. The primary benefit to TDOT is increased service life and improved performance of bridge decks. The increased service life and improved performance decrease maintenance and replacement costs. Further, longer service life and improved performance reduce maintenance incursions into traffic thus reducing congestion and delays. Finally, and perhaps the most importantly, improved performance (less reinforcement corrosion) increases the safety of traveling public. Second, less frequent maintenance and replacement of bridge decks lowers TDOT carbon footprint by using less Portland cement. Third, a less evident benefit is team building and increased cooperation. By investigating federal and industry points of view, TDOT is increasing team building and fostering a beneficial cooperative working atmosphere. Tuesday, December 20, 2011 Page 5 of 11

9 Project Title: Social Norms Media Campaign Related to Alcohol and Other Drugs Prevention Activation Amount: $2, Agency: Tennessee Independent Colleges and Universities Association PI - Patricia Smith, Counseling Center Social Norms Media Campaign related to alcohol and other drug prevention funds will be used to purchase media materials for alcohol and drug prevention. These materials will include such items as posters and incentive items. The posters will be displayed throughout campus where students congregate. The incentive items will be given away at health fairs, career fairs, and other campus activities. The materials must contain a statement regarding a message about alcohol and drug prevention.

10 Project Title: Developing Rating Aids for the Evaluation of Existing Concrete Box Culverts in Tennessee Activation Amount: $14, Agency: Tennessee Department of Transportation PI - Sharon Huo, Civil and Environmental Engineering Support Personnel - Anthony Greenway, Energy Center The objective of this research is to develop appropriate rating aids for the evaluation of existing concrete box culverts in Tennessee. These rating aids will allow bridge evaluators to efficiently rate existing culverts and make the culvert rating an efficient and sustainable practice, consequently helping TDOT comply with the NBIS FHWA load rating requirements for existing culverts. It is expected that this project will improve the culvert management in the state, preserve the state's investment in the transportation infrastructure, and provide a safer roadway for the traveling public.

11 Project Title: Developing a TDOT Class S-LH (Lower Heat) PCC Mixture Specification Activation Amount: $13, Agency: Tennessee Department of Transportation PI - L. K. Crouch, Civil and Environmental Engineering Senior Personnel - Benjamin Mohr, Civil and Environmental Engineering Senior Personnel - Daniel Badoe, Civil and Environmental Engineering Support Personnel - Anthony Greenway, Energy Center American Concrete Institute Report indicates that mass concrete creates potential for significant temperature differentials between the interior and outside surfaces of the structure. Volume changes and restraint result in tensile strains and stresses that may cause cracking detrimental to the structure. A 2002 Concrete International article indicated that "mass concrete" only required a least dimension greater than 3-feet using a mix that contained more than 564-lbs/CY of cementing materials. TDOT commonly uses many such structural elements but has no low heat of hydration mixture specifications. The proposed study builds on the findings of an unfunded 2004 TTU study requested by TDOT Materials & Tests Division and Region 4 on heat of hydration. Benefits to TDOT include: 1) extended service life of structural elements with less thermal cracking (better durability and structural integrity); 2) fewer traffic delays for maintenance/reconstruction/replacement of structural elements; 3) lower cost of structural elements (both initial and life cycle); 4) greater use of supplementary cementing materials improves TDOT's environmental stewardship; and 5) lessons learned in the proposed study would be applicable to TDOT Class A PCC and other large placements TDOT Standard Specifications Section (Class S) requires a minimum cementing materials content of 682-lbs/CY and only allows 25% fly ash substitution for Portland cement. A concrete mixture meeting this specification has the potential to generate a lot of heat and induce thermal cracking in structural elements. The purpose of this study is to reduce the heat generation of TDOT Class S PCC while maintaining adequate values of other engineering properties. In general, the research team will develop and evaluate five lower heat PCC mixtures. The "best" lower heat PCC mixture will be compared to a typical TDOT Class S PCC mixture in a large instrumental field placement. Further, the lower heat modifications will be tried on TDOT Class A PCC. Tuesday, December 20, 2011 Page 11 of 11
