N2  - The objectives of this research were to develop laboratory tests for pre-evaluating aggregates and paving mixtures to predict skid resistance properties in the field and to evaluate field installations for correlation of field and laboratory polishing exposures. A usable correlation was found between British portable tester measurements and field skid-trailer measurements at test speeds of 20, 30, 40, and 50 mph (32.19, 48.28, 64.37, and 80.47 km/h). Different correlations were obtained for open-graded mixes and for dense-surface mixes. Field wear versus laboratory wear correlation was attempted by coring pavements after field testing and then polishing cores to terminal polish in the circular-track machine. The full "as new" polish curve was obtained by remixing and molding unworn portions of the field cores into laboratory specimens for polish in the circular-track machine. New and worn polish curves when compared gave the extent of cricular-track wear experienced in the field. Comparisons were valid for that mix only and could not be combined from different mixes to give a traffic exposure versus circular-track equivalency. It was possible, however, to establish an upper limit for field wear equivalent to 3 hours or less of machine wear. The establishment of an upper limit allows prediction from laboratory tests of maximum field polish that may be anticipated for a given pavement mixture design. Examples are given in the report.<p /> <p>Language: en</p>
