One method of controlling embankment densification refers to the maximum density observed in a local control strip. The local maximum is the standard against which all mainline densities are compared, yet research to date has not addressed the precision of what is truly an estimated maximum density. The precision of the maximum-density estimate is quantified by simulating typical rolling procedures and density-growth curves with pertinent parameters, such as the decision rule and sample size, controlled in a factorial design. Analysis of the simulation results leads to the following general findings: (a) The sampling plan with the same locations and correlated comparisons is the most efficient of the four plans investigated, and (b) by employing this plan, the true relative density will be greater than 90 percent about 95 percent of the time.
