11. Procedure11.1 Measure the grade

11.程序<br>11.1测量与试样相邻的人行道的坡度和坡度。<br>11.1.1如果交叉斜率和坡度均小于0.5％，或水浸入试样，则不得在野外进行测量。<br>11.1.2在实验室中进行的测量应使试样位于2％的交叉斜率和1％的坡度上。<br>11.2将润湿装置放在试样上，确保润湿区域与试样保持一致。<br>11.3打开润湿设备的泵，检查压力，并确认测试样品以2.0±0.2 in./h的速度均匀润湿。<br>11.4将润湿装置放在适当的位置，轻轻地将后向反射仪放置在适当的位置，以便可以通过润湿装置的开口进行测量。<br>11.5让润湿装置运行足够长的时间以使试样饱和。这可能需要30秒到几分钟的时间，具体取决于标记的类型以及在进行此测试之前是否在同一样本上运行TestMethod E2177（通常被认为是一种好习惯）。一旦标记饱和，继续操作润湿设备，并开始以十秒的间隔获取仪器读数，直到回射值达到稳定状态为止。如果标记在五分钟内未达到稳定的陈旧状态，则结果应报告为不确定。<br>11.6一旦达到稳态条件，就开始记录每个试样的仪器读数。至少记录四个读数。

11. 程序<br>11.1 测量与试样相邻的路面的坡度和横坡。<br>11.1.1 在交叉坡度和坡度均小于 0.5% 或水淹没试样时，不得进行现场测量。<br>11.1.2 实验室的测量应在试验样品停留在百分之二的横坡和百分之一的坡度上。<br>11.2 将润湿装置放在试样上，确保湿液区域与免试样对齐。<br>11.3 打开润湿装置泵，检查压力，并验证试样是否均匀地在 2.0 ± 0.2 in./h 的气管下进行润湿。<br>11.4 在润湿装置就位时，轻轻地将倒光仪放在就位，以便通过润湿装置中的开口进行测量。<br>11.5 让润湿装置工作足够长的时间使试样饱和。这可能需要 30 秒到几分钟的时间，具体取决于标记类型以及 TestMethod E2177 是否在运行此测试之前在同一试样上运行（通常被认为是一种良好做法）。标记饱和后，继续操作润湿设备，并开始每隔十秒钟进行测量读数，直到反射值达到稳定状态。如果标记在五分钟内未达到稳定的陈旧状态，则结果应报告为未确定。<br>11.6 达到稳定状态条件后，开始记录每个试样仪器读数。记录至少四个读数。

11. Procedure11.1 Measure the grade and cross slope of the pavement adjacent to the test specimen.11.1.1 Measurements in the field shall not be made where both the cross slope and grade are less than 0.5 percent, or where the water submerges the test specimen.11.1.2 Measurements in the laboratory shall be made with the test specimen resting on a two percent cross slope and a one percent grade.11.2 Place the wetting device on the test specimen making sure that lhe wetting area is aligned with the lest specimen.11.3 Turn on the wetting device pump, check the pressure, and verify that the test specimen is being uniformly wetted at a rale of 2.0 ± 0.2 in./h.11.4 With the wetting device in position, gently place the retroreflectometer in position so that it can measure through the opening in lhe wetting device.11.5 Allow the wetting device to operate long enough to saturate the test specimen. This may take 30 seconds to several minutes, depending on the type of marking and whether TestMethod E2177 was run on the same specimen immediately prior to the running of this test (which is generally considered to be a good practice). Once the marking has been saturated, continue operating the wetting device and begin taking instru¬ment readings at ten second intervals until the retroreflective values reach a steady state condition. If the markings do not reach a steady stale condition within five minutes, then the results shall be reported as undetermined.11.6 Once steady state conditions have been achieved, begin recording instrument readings for each test specimen. Record a minimum of four readings.<br>
