    摘要:

    不黏轮乳化沥青是一种解决沥青路面施工中 “黏轮问题 ”的关键材料,其中不黏轮效果是其核心指标。不黏轮效果准确评价对不黏轮乳化沥青推广应用至关重要。该文 基于国内外研究成果创新提出两种不黏轮效果试验方法 (配重法、压头法 ),并对多种乳化沥青进行不黏轮效果评价。试验结果表明:两种试验方法 (配重法、压头法 )能够较好地评价乳化沥青的不黏轮性能且试验结果具有很好的一致性。其中配重法适合于工程现场快速评价,压头法适合于科学研究、试验检测分析。两种试验方法设备简单、操作方便,适用于工程现场、室内研究等多种场景的不黏轮乳化沥青不黏轮效果评价。

    Abstract:

    The wheel sticking-free emulsified asphalt is a key material to solve the wheel sticking problem in the process of asphalt pavement construction,with the wheel sticking-free effect as the core index.The accurate evaluation of the wheel sticking-free effect is important for the popularization and application of wheel sticking-free emulsified asphalt.Based on the research results in China and abroad,two test methods for wheel sticking-free effects (counterweight method and indenter method ) were innovatively proposed,and the wheel sticking-free effects of various emulsified asphalt were evaluated.The test results show that the two test methods can accurately evaluate the wheel sticking-free performance of emulsified asphalt,and the test results are in good agreement.Specifically,the counterweight method is suitable for rapid evaluation on construction sites,and the indenter method is suitable for scientific research,testing,and analysis.The two test methods require simple equipment and convenient operations,and they are suitable for the evaluation of wheel sticking-free effects of wheel sticking-free emulsified asphalt in various scenes such as construction sites and indoor research.
