    Abstract: 純瀝青材料的性質如:黏度、延
    性與黏結力易受環境溫度影響。使用
    瀝青鋪設之路面常出現疲勞龜裂、低
    溫龜裂、老化、車轍和剝離等現象。
    輪胎經熱裂解後產生之炭質物因具
    與碳黑相似的結構,因此本研究探討
    廢輪胎熱裂解碳黑對瀝青機械性質
    的影響。利用不同粒徑之裂解碳黑與
    添加量對瀝青針入度、黏度、硬度等
    性質之影響。
    The surface acidic functional groups of chars by
    pyrolysis of used tires, at atmospheric and under
    reduced pressure, and of commercial blacks were
    investigated. Char obtained under reduced pressure
    has the highest amount of acidic groups, while char
    obtained at atmospheric pressure has similar surface
    and carboxyl content after extraction with toluene for
    eight hours. The particle size and content of char
    obtained at atmospheric pressure used in this study
    (100、300、500 mesh each with3、6、9%)
    shows little or no effect on softening point and
    viscosity. This suggested that char could be used as
    filler in asphalt with at least 9% char blends.
