| 摘 要： | 先对掺入相同百分比但不同组合方式的SBS及PE改性剂的改性沥青进行技术分析,然后对SMA采用普通沥青和不同组合的改性沥青之间的成本进行估算,最后在几种组合当中得出使用PE SBS的混合改性剂优于同剂量的PE、次于SBS,但就技术性和经济性而言,综合指标好。

| Abstract: | It analyses the technological performance of the modified asphalt with SBS and PE at the same percentage,but in different mode at first, then estimates the charge of SMA which adulterates normal asphalt and different kinds of modified asphalts. This paper takes SBS and PE for example. Finally among these different kinds of combinations, the mixed modified materials not only in technology but in economy present obvious advantages, which though the result is less good than the same amount of SBS. |
