Novel emulsified asphalt mixing time tester

Abstract

The invention relates to a novel emulsified asphalt mixing time tester. The novel emulsified asphalt mixing time tester mainly comprises a bracket, a material containing bucket, agitating blades, a dynamic torque sensor, a controller, a data acquisition system, a connector, a rotary shaft, a rail and a motor. The agitating blades, the dynamic torque sensor, the controller and the motor are connected together through the rotary shaft from bottom to top and are connected to the bracket through the rail; the controller is arranged at the upper part of the bracket; the material containing bucket is mounted at the lower end of the bracket. The invention provides the emulsified asphalt mixing time tester capable of realizing an accurate testing result. With the adoption of the tester, the mixing time of emulsified asphalt can be accurately determined and the non-construction time of the emulsified asphalt can also be determined. The mixing time tester is also applicable to the test of the mixing time of concrete and the like.

Description

Technical field: [0001] The invention relates to a testing technique for emulsified asphalt, in particular to a testing instrument for the mixing time of emulsified asphalt. technical background: [0002] The mixing time of emulsified asphalt is an important indicator of mixed emulsified asphalt. In engineering, the length of mixing time is often used to evaluate the operable time of slurry mixture, and the compatibility of the mixture is qualitatively judged according to the test molding conditions. Bad. [0003] At present, the determination of the mixing time of emulsified asphalt at home and abroad is mainly based on the experience of the test personnel. The test results are greatly affected by human subjectivity, and it cannot be accurately determined according to the standard speed of 60-70r / min. time. At the same time, the method of mixing with a mixing spoon (similar to mixing emulsified asphalt mixture in a container with a spoon) cannot well simulate the actual e...

Problems solved by technology

[0003] At present, the determination of the mixing time of emulsified asphalt at home and abroad is mainly based on the experience of the test personnel. The test results are greatly affected by human subjectivity, and it is impossible to accurately determine the mixing time according to the specification of 60-70r / min. time

At the same time, the method of mixing with a mixing spoon (similar to mixing emulsified asphalt mixture in a container with a spoon) cannot well simulate the actual engineering mixing situation, and the conclusion drawn is only a rough mixing time
