GTM是一个优良的研究工具,但决不是一个混合料设计工具,这是我要表达的全部观点。读了《中国公路》杂志2005年第13期的文章《GTM的开发与应用》后,觉得有必要对GTM的开发与应用说几句。GTM是英文Gyratory Testing Machine的缩写,在中国被称为美国陆军工程师兵团旋转试验机,是由美国人JohnMcRae发明的。这是一台性能优良的试验机,但不是一个所谓GTM混合料设计方法的工具。GTM生产的混合料非常密实,但十分干枯,沥青用量比正常情况至少要低1%,抗疲劳
GTM is a good research tool, but by no means a compound design tool, which is all I want to say. After reading the article “Development and Application of GTM” of China Highway Magazine No. 13 in 2005, I feel it is necessary to say a few words about the development and application of GTM. GTM English acronym Gyratory Testing Machine, known in China as the United States Army Corps rotation test machine, was invented by the American JohnMcRae. This is a good testing machine, but not a tool for the so-called GTM mix design method. GTM produces very dense mixes but is very dry with at least 1% less bitumen than normal, with resistance to fatigue
