摘要
针对胶粉改性沥青性能及其影响因素,通过室内试验研究了不同目数的胶粉对橡胶沥青性能的影响,并对各指标数据回归分析。试验结果表明,胶粉改性沥青高温性能、粘韧性和韧性分别在目数为40时出现峰值,低温性能在目数为40时出现谷值,而弹性恢复性能随着胶粉目数的增加提高。
According to the rubber modified asphalt performance and influential factors,the paper researches in the influence of the various rubber powder with different mesh numbers on the rubber asphalt by indoor tests,undertakes the regression analysis of all sorts of indexes and data,and proves by the test result that the peak value of the rubber powder modified asphalt＇s high-temperature performance and its sticky toughness and toughness appear when the rubber mesh number is 40,while the valley value of the low-temperature performance occurs when the rubber mesh number is 40,and the elastic resuming performance is improved with the increase of the rubber mesh number.
