| 摘要： | In 1978 the Metrology, Standards, and Materials Division of the Research Institute at King Fahd University of Petroleum and Minerals (KFUPM/RI) launched an in-house research study on sulfur-asphalt pavement development because sulfur produced in Saudi Arabia was available in abundance and the international price of paving asphalt was soaring because of the energy crisis. Among the various available techniques of substituting asphalt with sulfur, the sulfur-extended asphalt (SEA) paving technology developed by Gulf Canada was considered to be the closest to practical applications. Three SEA test roads were laid in the Eastern Province in cooperation with Gulf Canada and the Ministry of Communication (MOC), Saudi Arabia, as a part of the ongoing road development program of MOC. A sulfur/asphalt ratio of 30/70 by weight was used in Test Road 1 (Kuwait Diversion) and Test Road 3 (KFUPM), whereas a higher percentage of 45/55 was used in Test Road 2 (Abu Hadriyah Expressway). Performance of the three test roads has been monitored from time to time. For each test road, the control section using the normal asphalt concrete has shown a better performance than the SEA sections. |
