为研究因沥青混合料中掺加外掺剂后对沥青胶浆高低温性能的影响,结合《六盘山地区公路修筑技术研究》课题研究工作,通过进行沥青胶浆的高温针入度、软化点、低温蠕变等3项室内试验,对沥青胶浆使用纯矿粉和掺加外掺剂后试验指标的变化来研究其高低温性能的变化,并提出选择使用外掺剂种类的原则,推荐采用的合理粉胶比和外掺剂剂量。
In order to study the influence of adding admixture on the high and low temperature properties of asphalt mortar, the research work on the technical research of highway construction in Liupanshan area was carried out. Through the high temperature penetration of asphalt mortar, softening point , Low temperature creep and other three indoor tests. The changes of the high and low temperature properties of asphalt mortar after using pure mineral powder and admixture with external admixture were studied. The principle of selecting the type of external admixture was proposed. The use of a reasonable ratio of powder and external admixture dose.
