Federal Highway AdministrationUS Transportation CollectionThe objective of this research is to characterize the heat generation in mass concrete placements typically encountered by GDOT in its construction projects, to create an analytical method for determining the cooling requirements for mass concrete, and to develop a comprehensive guideline for transportation infrastructure applications. This guideline was derived from an extensive review of technical literature and various state DOT\u2019s specifications, analytical modeling of heat generation in transportation structures, and laboratory and field research of mass concrete cooling. The guideline can allow GDOT to more efficiently evaluate contractor\u2019s proposed mass concrete cooling methods, which would result in improved quality of concrete transportation infrastructures in Georgia.78
