一、简介从国内外的发展过程和现状来看,由于马歇尔试验、劈裂试验、弯拉试验和闭式三轴试验等四种试验方法,基本上能满足在沥青混凝土配合比设计和检验产品质量时进行各项力学性能试验的要求,所以得到了普遍的使用。在进行这四种试验中,除要配置专用加压夹具外,均按传统方法在万能材料试验机上进行。加压过程由人工控制,试验数据的读数和计算均由人工完成。这种方法控制步骤复杂(尤其
I. Introduction From the development process at home and abroad and the status quo, due to the Marshall test, split test, bending test and closed three-axis test four test methods, basically to meet the mix design and testing of asphalt concrete products When the quality of the mechanical properties of the test requirements, it has been widely used. In carrying out these four kinds of tests, in addition to the configuration of special pressure fixture, according to the traditional method of universal material testing machine. The pressurization process is controlled by hand and the readings and calculations of the test data are done by hand. This method of control steps are complicated (especially
