Abstract:

This research project focused on evaluating the performance of internally cured concrete mixtures for bridge deck and pavement with the aim of reducing volumetric changes, i.e., cracking and warping. The specific tasks conducted in this project include a literature review of internal curing technology and experiences in the US, a survey of existing bridge decks using internal curing in the state of Illinois, an evaluation of different materials as internal curing agents, and the effect of the use of internal curing in two different concrete mixtures for concrete bridge decks and pavement, respectively. During the material evaluation stage, fourteen different materials were evaluated for absorption and desorption characteristics. These materials can be categorized in three different groups: lightweight aggregate fines (LWA), superabsorbent polymers (SAP), and fibers. Based on the results of their captivity characteristics, one LWA and one SAP were selected for use and implementation in concrete mixtures. During the evaluation of performance of internally-cured concrete (ICC), determination of fresh and hardened concrete properties was conducted for one control and two ICC (one with LWA and one with SAP) at two different water-to-cementitious materials ratio (w/cm). Results showed evidence of improving the volumetric stability and durability of ICC when the w/cm ratio was 0.36. Negligible improvements were observed at a w/cm ratio of 0.45. Additionally, service life modeling for a bridge deck scenario and a life cycle cost analysis (LCCA) for a pavement project were conducted. It was concluded that the service life of bridge decks can be extended by using ICC, and that the LCCA of a ICC pavement can be reduced compared to a control scenario. Finally, recommendations for implementation into the Wisconsin Department of Transportation Specifications are provided.
