Research Solutions: Evaluating the Use of Very Early Strength Latex-Modified Concrete as a Bridge Overlay, TR-771, 2025
Get PDFConventional bridge deck overlays made with high-performance concrete (HPC) and low-slump dense portland cement concrete (PCC) generally require a 72-hour wet curing time before they can be opened to traffic. Shorter opening times are desired to reduce the high cost of traffic control for heavily traveled urban highways. To meet this need, high early strength latex-modified concrete (LMC-VE) overlays are designed to open to traffic within 3 to 6 hours of placement. Research indicates that LMC-VE overlays are less prone to shrinkage-related problems and more resistant to chloride penetration than other early strength overlays. The high initial cost can be offset by the reduced need for traffic control and the extension in bridge deck service life by an additional 30 years, reaching a total service life of over 75 years. In September 2019, the Iowa Department of Transportation placed Iowa’s first LMC-VE bridge deck overlay on the IA 15 bridge over Black Cat Creek in Emmet County. In this research, the overlay construction activities were thoroughly documented, and LMC-VE specimens were cast in the field to investigate a range of mechanical and durability properties in the laboratory. Additionally, the field overlay’s performance was monitored for 50 months through frequent field visits and testing. Lastly, a life-cycle cost analysis (LCCA) was performed to assess the economic value of the LMC-VE overlay relative to other overlay types. The laboratory tests indicated that the LMC-VE mix reached 2,827 psi at 3 hours, which is sufficient for quickly opening a pavement to vehicular traffic, and exhibited sufficient long-term compressive and flexural strength, good chloride penetration resistance and high surface resistivity, comparable shrinkage and initial sorptivity to PCC, and mixed results for freeze-thaw durability. During field monitoring, the overlay exhibited some thin cracks, slight palling/abrasion in a few localized areas, a slight decrease in friction over time, comparable initial and secondary sorptivity to HPC, and a good substrate-overlay bond. The LCCA results suggest that the high life-cycle cost of the LMC-VE overlay outweighs the lower user costs. However, when annual average daily traffic (AADT) values are above 3,300, the LMC-VE overlay could be a better alternative. The results of this research are expected to serve as a benchmark and assist in decision-making related to the selection of overlay alternatives for future bridge deck applications in Iowa

IHRB At-a-Glance 2024
No full textThe IHRB is an advisory board responsible for assisting the Iowa Counties, Iowa Cities and Iowa DOT in the development and continuation of an effective program of research and development in highway transportation. Board membership includes representatives of Iowa's city and county government highway agencies, the Iowa DOT, and Iowa's public universities. IHRB was established in 1949 to provide guidance and oversight for the use of the primary, secondary, and municipal road research funds. Years later, the IHRB is still fulfilling that role, overseeing about 20 new projects each year involving transportation issues in Iowa. The value earned from this research is continually returned to Iowa taxpayers multifold through cost savings of innovations, improved safety, and the implementation of proactive technologies. This is a summary of IHRB research activity in 2024
