RECYCLING RECLAIMED ASPHALT PAVEMENT. RESEARCH REPORT

After completing a study of milling and planning flexible pavement, the next logical step was to find a use for the surplus reclaimed asphalt pavement (RAP). Recycling RAP is a concept that has garnered significant interest periodically since about 1915, whenever petroleum shortages threatened. In the mid-1970s it again became timely. From 1976 through 1983, three recycling experiments were performed on rural state highways. They were 1) a 100-percent recycled, synthetically rejuvenated top course, 2) a top course recycled untreated as a shoulder base course, and 3) an asphalt-cement rejuvenated top-course material recycled as a 35/65 base course (35-percent recycled, 65-percent virgin material), a 35/65 top course, and a 50/50 top course. In the first two experiments on-site top courses were milled, stockpiled (short-term) and later recycled, and the third material from existing stockpiles was recycled after long-term shortage.
