Abstract

The Arizona Department of Transportation evaluates portland cement concrete pavements by testing with mechanical as well as electronic profilographs. The precision of the two types of profilograph was evaluated. More than 100 profilograph runs were conducted on a selected pavement section. The range of replicate readings of pavement profile index could be as much as 2.0 in./mi for a rough pavement. Electronic profilographs adjusted to operate at low filter settings gave lower profile index values than those obtained with the same profilographs at higher filter settings.
