SMA 混合料的原材料质量控制及配合比设计初探

摘要

介绍了 SMA 在国内外应用的现状和特性，并在保证路面质量的基础上，提出了 SMA 混合料的选择要求，指出在实际工程中应严格按照规范三个阶段的要求，分别进行目标配合比设计，确定生产配合比，再验证生产配合比，以确定施工工艺和流程，确保施工质量。%The paper introduces the status and features of SMA application at home and abroad,points out the selection requirement of SMA mix-er based on ensuring the roadbed quality,and points out the demands for the regulations for three phases should be strictly adhered to in the pro-jects,and undertakes the aim proportion ratio by identifying and recalculating the production proportion ratio,so as to ensure the construction craft and procedure,as well as construction quality.
