Concrete Mixture Proportioning
Concrete pavement owners care most about a pavement’s long-term performance—its durability and strength. Contractors care more about its constructability—its workability, setting, and early strength that constrain when their next phase of work can begin. Both care about their bottom line.
No one-size-fits-all concrete recipe exists. Mixture proportioning is the iterative process of determining how much of which ingredients available in a given locale can most economically produce the best concrete matching pavement requirements.
The following CP-Tech-Center-curated collection of resources is not comprehensive, but it does represent the current state of concrete mixture proportioning research and best practice. See also the CP Tech Center’s collection of resources on Performance-Engineered Mixtures (PEM).
