The Portland Cement Association (PCA) reports that state DOTs maximize funds by using life-cycle cost analysis, alternate design/alternate bidding, and mechanistic-empirical pavement design. While each tool addresses inefficiencies by identifying full, long-term costs from a project's beginning, combining them reaps the greatest benefits.
“This white paper illustrates how using them together allows states to do more with the money they have,” says PCA President Brian McCarthy. “To not fully utilize these tools is to misuse millions of taxpayer dollars.”
Indiana, Louisiana, and Missouri are used to demonstrate potential efficiencies. Indiana, for example, saved more than $10 million on 23 projects just by using mechanistic-empirical pavement design.
