Oregon has been using open-graded hot mix on its roadway system since the late 1970s. Because of the performance of these early jobs (and the continued good performance of these mixes), open-graded hot mix has been the preferred choice for a surface course on Oregon highways. The following are described with respect to the use of these mixes in Oregon: historical perspective; design, including mix and structural design; construction, including quality control/quality assurance considerations; and maintenance and rehabilitation practices with porous pavements. The continued success of the use of these materials from both a performance and a public acceptance standpoint indicates they will be the pavement of choice in Oregon for the foreseeable future.
