【摘要】：為了研究HDPE改性瀝青制備工藝,以AH-90#瀝青為基質瀝青,通過正交試驗和方差極差顯著性分析,得到HDPE摻量、剪切速率、剪切時間和加熱溫度4個因素對HDPE改性瀝青指標的影響規(guī)律。通過分析,確定制備HDPE改性瀝青最佳工藝參數(shù)為:剪切速率為4 500r/min,剪切時間為25min,加熱溫度為170℃,改性劑HDPE摻量為5%。研究結果可為HDPE改性瀝青的制備和應用提供依據(jù)。
[Abstract]:In order to study the preparation process of HDPE modified asphalt, the content and shear rate of HDPE were obtained by orthogonal test and variance significance analysis with AH-90# asphalt as base asphalt. The influence of four factors, shear time and heating temperature, on the index of HDPE modified asphalt. Through analysis, the optimum technological parameters of preparing HDPE modified asphalt are determined as follows: shear rate is 4 500 r / min, shear time is 25 min, heating temperature is 170 鈩，
