PERFORMANCE EVALUATION OF OPEN-GRADED ASPHALT CONCRETE MIXTURES USED IN OREGON

Oregon began using open-graded hot-mix asphalt concrete mixtures on its roadway system about a decade ago. In an attempt to assess the performance of the open-graded mix, a survey was made of some of the older projects. The evaluation shows that all the open-graded projects had excellent performance when compared to dense-graded projects. This included: (1) resistance to cracking is improved, (2) resistance to rutting is slightly increased, and (3) skid resistance is also improved. Measured noise levels did not show much difference, although the method of noise measurement may not have been capable of differentiating between the two types of mix. This evaluation supports the continuing use of open-graded mixture on the Oregon roadway system.
