Performance Contrast of Asphalt Macadam Based on Different Gradation
In order to study the influence of different gradation on asphalt macadam performance, three mixture gradations were utilized, and the low temperature anti-cracking performance, high temperature stability and water stability of the asphalt macadam mixture were studied. Through bending beam test, freeze-thaw split test and wheel track rutting test, the indexes of the mixtures were contrasted. The test result reveals that gradation has a rather remarkable influence on asphalt macadam performance, and when the 4＃ and 6# gradation are utilized, with rational coarse aggregate content and fine aggregate content, a favorable framework structure of the asphalt macadam mixture can be formed at the optimal asphalt content, which will result in excellent mixture performances.
