高分子改質瀝青於實務使用需探討儲存穩定性及拌和夯實溫度相關議題,本研究以不同儲存溫度和時間,藉由物理性質的變化,提出建議的儲存溫度,以及合適的儲存時間;另外,本研究提出決定改質瀝青之拌和夯實溫度的方法,藉由黏度-剪應變率圖中的趨勢線正推剪應變率134,100(1/s)下之瀝青黏度,再選擇以170 cP及280 cP對應到之溫度為拌和溫度及夯實溫度。最後,為確認建議拌和溫度應用在改質瀝青密級配混凝土之效果,比較改質瀝青混凝土與傳統瀝青混凝土的工程性質。建議改質瀝青最佳儲存溫度不要高於170℃,儲存時間不要大於5天;改質瀝青的拌和夯實溫度在實驗室和現地瀝青拌和廠存在約20-35℃的差異,需以拌和廠實際狀況作為考量;而改質瀝青混凝土在回彈模數、穩定值、間接張力及車轍試驗皆符合規範要求,且優於傳統瀝青混凝土。
Using polymer modified asphalt (PMA) have to discuss some problems such as storage stability and mixing temperature. In this study, we provide a suitable storage temperature and time on the basis of varieties of physical properties in different storage temperature and time. Besides, according to the trendline of viscosity - shear rate charts, mixing and compaction temperature of PMA can be determine by pushing 134,100 (1/s) shear rate and selecting viscosity with 170 and 280 centipoise (cP). In order to confirm the effect of this mixing temperature using in PMA dense graded concrete, this study compares engineering properties of PMA and traditional asphalt concrete. Finally, the recommended storage temperature is not higher than 170 degrees and time is not more than 5 days. The mixing and compaction temperature of PMA has 20-35 degrees differences in the laboratory and hot mix asphalt (HMA) plant, so it need to consider the actual situation. The resilient modulus, stability value, indirect tension, and wheel track test of PMA concrete met the specification, and are better than traditional asphalt concrete.
