| 摘 要： | 简介并分析了ASTM现行的测定与回收乳化沥青残余物方法。根据设备投资费用、试验时间与温度以及试样量对诸方法进行了对比和尝试性地评价。ASTMD7404试样用量少，比其它方法快捷，可用作快速、定量测定乳化沥青残余物的方法。如果不需要进一步试验，ASTMD6934为一种简单的测定乳化沥青残余物方法。为获取进一步试验用所需残余物，宜考虑选择蒸馏法ASTMD6997和ASTMD7403，若乳化沥青中含有聚合物，即改性乳化沥青，则以采用ASTMD7403为宜；ASTMD7497实验条件接近路用条件，因而适合于为研究珐余物性席而蓑墩张会物．

| Abstract: | The current ASTM standard test methods and practices for recovery and determination of residue of emulsified asphalts were briefly introduced and compared.The methods and practices were evaluated based on equipment cost,procedure time,test temperature and sample volume.ASTM D7404 has a shorter test cycle time and less material required compared to the others.The methods could be used as a rapid and quantitative determination of the residue in emulsified asphalts.ASTM D6934 could be used as a simple method f... |
