The results of the research show first that HVFA PCC meets all TDOT 604.
To identify innovative methods to overcome barriers to HVFA use in pavements and transportation structures, the FHWA Exploratory Advanced Research (EAR) Program is sponsoring a study called Greatly Increased Use of Fly Ash in Hydraulic Cement Concrete for Pavement Layers and Transportation Structures.
The report considers all aspects of HVFA concrete production, from the characterization of the starting materials, through mixture proportioning and curing options to achieve desired properties, to the in-place early-age and long-term performance of the concrete in its fresh and hardened states.
