近年来,随着交通运输业的发展,公路工程随之不断增多,沥青混凝土以其自身诸多的优点被广泛应用于公路路面施工当中。然而,沥青混凝土的离析问题却一直困扰着施工人员。一旦沥青混凝土发生离析,则会造成路面早期损坏,进而影响公路的使用寿命。为此,必须采取相应的控制措施和方法降低沥青混凝土离析的发生,而对离析的评价能够帮助施工人员找出问题出现的根源。基于此点,本文首先介绍了沥青混凝土离析产生的原因及其危害,并在此基础上提出沥青混凝土离析的主要评价方法。
In recent years, with the development of the transportation industry, highway engineering has been increasing. Asphalt concrete has been widely used in the construction of highway pavement due to its many advantages. However, the segregation of asphalt concrete has been plagued by construction workers. Once the asphalt concrete segregation, it will cause early damage to the road, thereby affecting the service life of the road. To this end, we must take appropriate control measures and methods to reduce the occurrence of asphalt concrete segregation, and evaluation of segregation can help constructors to identify the root causes of the problem. Based on this point, this paper firstly introduces the reasons and the harms of asphalt concrete segregation, and on this basis puts forward the main evaluation methods of asphalt concrete segregation.
