乳化沥青粘结力测定仪

乳化沥青粘结力测定仪,沥青实验仪器

 

 

乳化沥青粘结力测定仪是专业沥青检测仪器,用于测定乳化沥青稀浆封层混合料达到完全固化所需的时间,用以确定乳化沥青稀浆封层混合料施工后早期开放交通的时间使用前务必仔细阅读说明书。

Emulsified asphalt adhesion tester is a professional asphalt testing instrument used to determine the time required for the emulsified asphalt slurry seal mixture to fully cure, to determine the time of early open traffic after the construction of the emulsified asphalt slurry seal mixture. Be sure to read the instructions carefully before use.

 

乳化沥青粘结力测定仪主要特点:

符合‘JYJ052-2000’标准中‘TO754-2000’的试验规范。

既可以做室内试验,也可以在施工现场使用;

制作精良,使用方便,测试结果准确可靠。

Main features of emulsified asphalt bond tester:
★ Meet the test specifications of ‘TO754-2000’ in the ‘JYJ052-2000’ standard.
★ It can be used for indoor test or at the construction site;
★Excellent production, easy to use, accurate and reliable test results.

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就是稀浆混合料的‘早期开放交通时间’

Emulsified asphalt adhesion tester test steps:
★ Place the test piece after initial setting under the pneumatic rubber pad of the adhesion tester and leave it for 15 minutes.
★ Press the base of the pneumatic rubber pad on the test piece and pressurize the instrument with a bicycle air pump or air compressor.
★ When the pressure of the instrument is expressed to 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, return the torque wrench force gauge to zero and cover the upper end of the cylinder, and smoothly and horizontally twist 90-120 degrees in 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 long, the interval can be extended to 30 minutes to repeat the test.
★ Repeat the test until the A high torque is reached, and the torque is constant.
★ Record the time when the high torque is reached, that is, the curing time. The curing time plus the initial setting time is the 'early open traffic time' of the slurry mixture.

 

乳化沥青粘结力测定仪试验报告:

报告应记述下列事项:

配制乳化沥青的乳化剂及沥青的品种,乳化剂用量,沥青含量。

矿料种类及级配。

乳化沥青稀浆封层混合料的固化时间。

Emulsified asphalt adhesion tester test report:
The report should describe the following:
Emulsified asphalt emulsifier and asphalt varieties, emulsifier dosage, asphalt content.
Mineral material types and grading.
The curing time of the emulsified asphalt slurry seal mixture.

 

乳化沥青粘结力测定仪注意事项:

仪器长期不使用,每半个月将活塞杆上下活动,如活塞过紧,需加润滑机油。测扭矩版搜也需每月转动几次。

Precautions for emulsified asphalt adhesion tester:
The instrument will not be used for a long time, and the piston rod will move up and down every half month. If the piston is too tight, it needs to be lubricated with oil. The torque test version also needs to be rotated several times a month.
