Economical and crack-free high-performance concrete (Eco-HPC) is a new class of environmentally friendly and cost-effective high-performance concrete (HPC) that is made of low binder content, high volume of supplementary cementitious materials (SCMs), and shrinkage mitigating materials. The initial phase of research that involved an extensive laboratory investigation indicated that the designed Eco-HPC can secure high resistance to shrinkage cracking, and high strength and durability. The aim of this project was to validate findings of the previous research via field implementation and develop guidelines for the use of Eco-HPC for sustainable transportation infrastructure construction. Two classes of Eco-HPCs were developed for field demonstrations: Eco-Pave-Crete made for pavement construction and Eco-Bridge-Crete for bridge construction. Compared to the MoDOT reference mixture, the optimized Eco-HPC mixtures developed for pavement and bridge applications exhibited approximately 40% lower embodied energy and 55% lower global warming potentials. The use of the proposed Eco-HPC mixtures could lead to reductions of about 4.7% of agency costs and 17.3% of the total life-cycle cost for bridge deck construction and 3.2% of agency cost and 6.2% of the total life-cycle cost for pavement construction in high traffic conditions.
