	<span style=\"line-height:1.5;\">为了探讨加载时间和的温度对废轮胎热解炭黑改性沥青混合料动态模量影响规律，本文采用常用级配AC-20，配制了废轮胎热解炭黑改性沥青、SBS改性沥青混以及70号基质沥青等三种沥青混合料，采用沥青混合料单轴压缩动态模量试验方法进行动态模量试验，得出试验温度与加载频率对三种沥青混合料动态模量的影响规律。实测的废轮胎热解炭黑改性沥青动态模量为沥青混合料路面设计提供参考。<br />
In order to study the effect of loading time and temperature on dynamic modulus of pyrolysis carbon black modified asphalt for waste tyres mixture, this paper adopts commonly used AC-20 to prepare three kinds of asphalt mixture such as pyrolysis carbon black modified asphalt for waste tyres, SBS modified asphalt mixture and asphalt 70 matrix. The dynamic modulus test was carried out by using the single axis compression dynamic modulus test method of asphalt mixture, and the effects of test temperature and loading frequency on the dynamic modulus of three kinds of asphalt mixture were obtained. The measured dynamic modulus of pyrolysis carbon black asphalt modified asphalt provides reference for pavement design of asphalt mixture.</span><span style=\"line-height:1.5;\"></span>
