摘要
橡胶沥青的特殊改性机理,使得其胶结料和混合料体现了极限强度和使用状态力学指标截然不同的变化。展示了这个显著的差异。分别利用力学模型和细观力学分析手法,解释了在宏观力学指标(极限和正常使用力学状态)差异产生的原因。在此基础上,参考国际上成熟应用橡胶沥青的国家和地区的相关规范,以及我国现行沥青路面技术规范,推荐了橡胶沥青及其混合料的技术指标框架体系。
Due to the special reaction between rubber powder and asphalt, rubber powder modified asphalt performs inconsistent changes between breaking strength and that of service modes; First, the inconsistent was presented. Then, the cause was explained by mechanical model and mechanical analyze. Base on the application and research experience, the technical criteria frame of asphalt rubber and hot mix had been recommended by reference to the countries that already have one.
