38、库妆捏烙醛容衙涂酒拯凸住忘邓饼究霸史晓岔请特通过上述定性分析，基于界面理论和溶解度理论来研究其混溶过程，可以认为胶粉与基质沥青在高温条件下充分混合发育，逐步发生熔胀、吸附、脱硫、降解等一系列物理化学反应：首先是胶粉颗粒吸收沥青中的轻质成分而熔胀并粘聚，同时在颗粒表面形成沥青质含量较高的凝胶膜，随着反应时间的增加，胶粉颗粒通过凝胶膜连接，形成一个粘度较大的半固态连续相的混溶体系；伴随着胶粉颗粒与沥青的熔胀过程，部分胶粉颗粒还会发生脱硫和分子降解过程，交联剂硫、抗老化剂等外加剂和炭黑等活性成分会通过界面交换作用进入沥青胶体体系，而未裂解的胶粉颗粒在沥青悬浮液中均匀分布，从而最终使混溶体系达到相对的

48、入到基质沥青以后，吸收轻质组分而膨胀，使沥青质含量相对增加，沥青胶体结构进一步向溶凝胶型及凝胶型结构发育，胶粉颗粒的掺量越多，粒径越细，发育越成熟，沥青的高温性能就越好。但是，需要注意的是：胶粉沥青在发育过程中，溶胀后的胶粉颗粒的体积将达到沥青胶结料体积的30%40%，胶粉沥青中较大胶粉颗粒的存在会使目前针入度试验中常用的标准针产生较大的随机误差，而且在25试验环境下，胶粉颗粒的变形能力比沥青弱，试针若插入到胶粉颗粒体上，会使针入度值偏小；若试针插入到胶粉颗粒体外，测得的针入度值又偏大，从而造成胶粉改性沥青针入度测试试验结果离散性较大。现代路面材料课程论文-废轮胎胶粉改性沥青应用技术综述Rv闰
