　　乳化沥青粘结力测定仪试验步骤：

　　★将初凝后的试件置于粘结力试验仪的气动橡胶垫下面，放置15分钟。

　　★将气动橡胶垫底座压在试件上面，用自行车气筒或空气压缩机向仪器加压。

　　★当仪器压力表达到0.72Mpa时，保持此压力，此时橡胶底座对试件的压力为193Kpa。

　　★达到压力并保持不变后，将测扭矩扳手测力表归零并套住气缸上端，在0.7-1秒内平稳、水平地扭转90-120度，并读取扭矩仪读数。

　　★升起橡胶底座，并擦干净底部待下次测试。

　　★此后每隔15分钟重复上述步骤。

　　★当固化时间较长时，间隔时间可延长到30分钟重复试验一次。

　　★重复试验直至达到A大扭矩，且此扭矩为定值时为止。

　　★记录达到大扭矩时的时间即固化时间，固化时间加上初凝时间**是稀浆混合料的‘早期开放交通时间’

　　Test steps of emulsified asphalt adhesion tester:

　　★Place the test specimen after the initial setting under the pneumatic rubber pad of the adhesion tester and leave it for 15 minutes.

　　★Press the pneumatic rubber pad base on the test piece,and press the instrument with a bicycle pump or air compressor.

　　★When the pressure of the instrument reaches 0.72Mpa,keep this pressure.At this time,the pressure of the rubber base on the test piece is 193Kpa.

　　★After reaching the pressure and keeping the same,reset the torque wrench force gauge to zero and cover the upper end of the cylinder,twist it smoothly and horizontally by 90-120 degrees within 0.7-1 seconds,and read the torque meter reading.

　　★Raise the rubber base and wipe the bottom clean for the next test.

　　★Repeat the above steps every 15 minutes thereafter.

　　★When the curing time is longer,the interval time can be extended to 30 minutes and the test is repeated.

　　★Repeat the test until a large torque is reached and this torque is a fixed value.
