    Abstract

    Components of variance were analyzed for 720 measures of concrete pavement texture depth obtained by the sand-patch method. The measurements were made in connection with a complete factorial field experiment involving four texturing methods used on two sections each of five different paving jobs. Each pavement section was tested at three different sites by three different operators performing two tests each. The analysis permitted estimates of the repeatability and reproducibility of the sand-patch test, as well as errors that can be expected in measuring the mean texture depths of a section of textured pavement.
