近年来,随着我国建筑设计能力的不断提高以及公路交通量的日益增多,沥青混凝土路面开始存在越来越多的质量问题。本文简要分析了沥青混凝土的级配种类,说明了在材料选择方面的主要原则,并对沥青混凝土的配合比实施三阶段配合比的设计方法,以便设计能够更加深入化与程序化,为沥青路面的有效建设提供强有力参考依据。 In recent years, with the continuous improvement of China’s architectural design capability and the increasing traffic volume of highway, more and more quality problems begin to exist in asphalt concrete pavement. This paper briefly analyzes the gradation types of asphalt concrete, explains the main principles in material selection, and implements the design method of three-stage compounding ratio of asphalt concrete mix so that the design can be further deepened and programmed. For the asphalt pavement Effective construction to provide a strong reference.
