近年来纳米技术正逐渐渗透到交通材料领域,纳米改性沥青即为其一种。碳纳米管有大量共轭键和环形结构,和SBS以及沥青的相容性比其他无机纳米材料更好。本文通过在基质沥青中添加碳纳米管和SBS改性剂对沥青改性,同时进行一系列的室内试验研究,结果表明：碳纳米管添加量在0.02%0.08%范围内,沥青的高、低温性能均能得到改善,碳纳米管对沥青的作用,必须是需要与SBS协同作用才能达到。
近年來納米技術正逐漸滲透到交通材料領域,納米改性瀝青即為其一種。碳納米管有大量共軛鍵和環形結構,和SBS以及瀝青的相容性比其他無機納米材料更好。本文通過在基質瀝青中添加碳納米管和SBS改性劑對瀝青改性,同時進行一繫列的室內試驗研究,結果錶明：碳納米管添加量在0.02%0.08%範圍內,瀝青的高、低溫性能均能得到改善,碳納米管對瀝青的作用,必鬚是需要與SBS協同作用纔能達到。

In recent years,materials with Nano-technique have been gradually used in the area of transportation.Nano-modified asphalt is a kind of them.Carbon nanotubes contains large amount of conjugated bond and circle structure,which has better compatibility with SBS and asphalt than other inorganic nano-materials.Carbon nanotubes and SBS modifier were added into asphalt to modify the performance of asphalt,and a series of experiments in laboratory were carried out.Results show that when the amount of carbon nanotubes is among 0.02%~ 0.08%,the performance of asphalt in both high and low temperature can be improved.Only by combining with SBS,the role of carbon nanotubes for asphalt can come into effect.
