This paper presents the results of a preliminary study that seeks to show how asphalt grading and air voids are related to the texture depth of asphalt. The fiftieth percentile particle size (D(50)) is shown to be a good predictor of texture depth measurements from a collected database of field and laboratory studies. The D(50) is used to normalise collected texture data and this 'relative texture' is shown to correlate with air voids. Regression analyses confirm that air voids should be included along with a measure of gradation in the interpretation of asphalt surface texture. The derived formulae are used to develop correlation charts.
