Abstract
The reasonable water consumption of foamed asphalt mixture is influenced by the content of foamed asphalt and mineral aggregate gradation. This paper studied the indirect tensile strength and dry density of foamed asphalt mixture model using three types of mineral aggregate gradation, four different asphalt contents and five kinds of optimum compaction water content. The results show that the foamed asphalt mixture has different indirect tensile strengths and dry densities with various mineral aggregate gradations, foamed asphalt contents and water consumptions. The optimum content of foamed asphalt is determined by 3% according to different gradations and water consumptions of asphalt mixture. The tests indicate that appropriate water consumption ranges are 65% -80%OMC, 70% -85%OMC and 70% -85%OMC for asphalt mixture OA,, OA2 and OA3, respectively. The conclusions are verified by a lot of test results.关键词
