　　Asphalt Mixtures-Applications, Theory and Principles
　　1 . Applications
　　Asphalt materials find wide usage in the construction industry. The use of asphalt as a cementing agent in pavements is the most common of its applications, however, and the one that will be considered here.
　　Asphalt products are used to produce flexible pavements for highways and airports. The term “flexible” is used to distinguish these pavements from those made with Portland cement, which are classified as rigid pavements, that is, having beam strength. This distinction is important because it provides they key to the design approach which must be used for successful flexible pavement structures.
　　沥青混合料的应用、理论和原则
　　1、应用
　　沥青材料如今在建筑行业广泛使用。沥青最常见的应用是作为的沥青路面的粘结剂使用。然而，这一点必须在这里予以介绍。
　　沥青产品常用于生产公路和机场柔性路面。所谓“柔性”是用来区分与硅酸盐水泥制成的路面，它被列为刚性路面，也就是这些路面具有刚性强度。这个区别很重要，因为它提出了成功进行柔性路面结构设计的方法的关键。
