SULPHUR-ASPHALT PAVEMENTS PERFORMANCE AND RECYCLING (WITH DISCUSSION)

Ontario constructed its first sulfur-asphalt test road in 1975, and since then has laid 3 more test pavements. In 1979, a paper was presented to the Association of Asphalt Paving Technologists by Fromm and Kennepohl which described the first 3 of these test roads and their properties. This investigation reports on the continued testing of the first 3 test roads, describes the construction and testing of a fourth test road, and details the lab testing and field trials for recycling a sulfur-asphalt pavement. A discussion section is also included.
