Research on Gradation Design of Asphalt Mixtur in Tropical Climate Region Hu Mingwu 1,a , Zhou Yitang 2,b , Li Luoke3 and Wang Yina 2 1 Highway Science and Technology Research Institute of Yunnan Province, Kunming 650051, China; 2 Kunming University of Science and Technology, Kunming 650224, China; 3 Harbin Institute of Technology, Harbin150090, China; a llk217@126.com, b ytzhou@yahoo.cn Key words: Asphalt mixtur; Gradation design; Bailey method; Coarse aggregat ratio; Road performance Abstract.
This Paper use the skeleton density and particle interfering theory to asphalt gradation design which draw on the three parameters basis of Bailey method, and introduce a new factor“q”,which represent the materials of filler in the coarse aggregate[1].Through a series of experiment, it found that the new indictor has notable effect on the dense skeleton structure formation ,which structure could decrease the rutting damage of high temperture and water damage of asphalt mixture in hot-humid region[2].
Materials and gradation design Test materials.Shell A-70 # asphalt, limestone aggregate,grounded furnace limestone slag were used as raw materials in this research .Table 1 shows the main technical characteristics of asphalt.
