1.1该方法使用一台试验机（图1），该试验机产生一个精确控制的旋转捏合过程，用于制备和测试沥青铺路混合料的样本。该方法旨在用于沥青混合料设计和控制测试以及加速交通模拟。目标是在预期垂直应力下压实至最终就地密度，同时根据单位质量和剪切阻力（包括塑性特性）监测过程。特别注意与压实现象相关的塑性特性的发展。 最大允许沥青含量直接由剪切应变逐渐增加（如旋转角度逐渐增加所示）以及剪切强度逐渐降低（如压路机压力逐渐降低所示）的第一个证据表示此处描述的程序用于混合设计和工厂控制以及加速交通模拟。 1.2本试验方法涵盖旋转试验机（GTM）的两种单独操作模式，即:（1）GTM油- 填充辊模式；和（2）GTM充气辊模式。对于充气滚筒，GTM机器角度根据旋转捏合过程中遇到的阻力而变化。因此，使用充气压路机的GTM被认为是充气轮胎和路面结构之间相互作用的更好的机械模拟。 1.3本试验方法适用于含有沥青水泥、沥青粘合剂、稀释沥青、沥青乳液的混合物。测试模具有4英寸。（101.6毫米），6英寸。（152.4毫米）和8- 在里面（203.2 mm）直径，相应高度为8英寸（203.2 mm），10英寸。（254.0毫米）和12英寸。（304.8毫米）。这些模具可容纳最大粒径为1英寸的颗粒。（25.4毫米）1.5英寸。（38.1毫米）和2.0英寸。（50.8毫米）。 1.4 单位 — 以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 1.5本标准的文本引用了提供解释材料的注释和脚注。 这些注释和脚注（不包括表和图中的注释和脚注）不应视为本标准的要求。 1.6 本标准可能涉及危险材料、操作和设备。本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 图1旋转试验机最大型号

1.1 This method employs a testing machine (Fig. 1) that generates a precisely controlled gyratory kneading process which is used to prepare and test specimens of bituminous paving mixtures. This method is intended for use in bituminous mixtures design and control testing as well as accelerated traffic simulation. The objective is to compact to the ultimate in place density under the anticipated vertical stress while monitoring the process in terms of unit mass, and shearing resistance including the plastic properties. Particular attention is given to the development of the plastic properties associated with the compaction phenomenon. The maximum permissible bitumen content is indicated directly by the first evidence of a progressive increase in shear strain (as indicated by a progressive increase in the gyratory angle) accompanied by a progressive reduction in shear strength (as indicated by a progressive reduction in roller pressure.) The procedures described here are for mix design and plant control as well as accelerated traffic simulation. 1.2 This test method covers two separate modes of operation of the Gyratory Testing Machine (GTM), namely: (1) GTM oil-filled roller mode; and (2) GTM air-filled roller mode. With the air filled roller, the GTM machine angle varies according to the resistance encountered during the gyratory kneading process. Thus the GTM using the air-filled roller is considered a better mechanical analog of the interaction between pneumatic tire and pavement structure. 1.3 This test method is for use with mixtures containing asphalt cement, asphalt binder cutback asphalt, asphalt emulsion. Test molds are available in 4- in. (101.6 mm), 6-in. ( 152.4 mm), and 8-in. (203.2 mm)diameters with corresponding height of 8-in (203.2 mm), 10-in.(254.0 mm), and 12-in. (304.8 mm) respectively. These molds can accommodate maximum particle sizes of 1 in. (25.4 mm) 1.5-in. (38.1 mm) and 2.0-in. (50.8 mm) respectively. 1.4 Units — The values stated in inch pound units are to be regarded as standard.
