Description
Technical field
The utility model belongs to asphalt performance technical field of measurement and test, it particularly relates to arrive a kind of pitch sampler.
Background technology
In road engineering, pitch is as a kind of important composition ingredient for ultimately forming mixture, in road surface overall structure
In play the role of it is cementing gather materials with fixation, the quality of asphalt performance will directly influence the quality of final road and use the longevity
Life.When asphalt performance is poor, phenomena such as easily passage in construction, and such as loose, deformation, hole will occur using early stage
The diseases such as slot and crack, and then influence road traffic.Important function based on pitch is right in theoretical research and actual production
Pitch is sampled inspection and just seems very necessary and key.Since plain asphalt is solid-state at normal temperatures, melting process needs
Higher temperature is wanted, and a large amount of fix-bitumens are fitted into storage tank rear sampling more difficulty, the required time that it is all melted
Longer, process is complicated, thus how to ensure that the sampling of pitch in this case has accuracy just to become one with representative
It needs to consider the problems of and solve.Therefore, designing a kind of can carry out accurate sampling in the pitch of different parts and just become ten
Divide necessity.How sampler extended into specific sampling point, and how to make asphalt melting and the outflow of sampling point
It receives to become and is critical to solve the problems, such as, can also become the asphalt sample taken out it is anticipated that reflect whole asphalt performances
Important evidence.
It is by the performance of sample come indicator and the whole pitches of reflection to be usually sampled analysis to a large amount of asphaltic products
A kind of method of performance, the sample of taking-up is accurate will to be made to be controlled about asphalt performance in experimental study or production；
If sampling does not have representativeness, have greater difference with actual production then desk research will be obtained, the testing result of gained, room
Interior research does not have any association with other practical various problems, keeps done detection and experiment nonsensical.China pair at this stage
Though pitch sampling has clear stipulaties and requires, since a large amount of pitches sampling difficulty is big, the especially pitch of solid-state storage causes
Ensure accurate sampling also not very good method in practice.For the drip stored in production or in desk research with solid-state
Blueness is sampled and is often melted to detect or study, whole pitches are melted and not only need longer time, and
And under higher temperature be also pitch occur aging lead to degradation；If at random from surface area, or after pitch is smashed from
Middle section samples, and the sample chosen area obtained in this way is fixed, and is represented comprehensively so that obtained bitumen samples do not have
Property.
Due to the appearance of the above problem, it is possible to make deviation occur to the control of construction quality.Even sometimes, obviously room
Interior experiment asphalt mixture design result is preferable, but real road various problems or sample occurs in construction and service stage in later stage
Pitch result is met the requirements, and the performance of asphalt mixture result mixed and stirred is poor etc..If such problem can be to pitch
Paid attention to when being sampled detection, and the sampling equipment by improving pitch under different storage states, then can effectively be subtracted
It is few that final road surface is caused to generate disease, and then the construction quality and service life of raising and road improvement because sampling inaccuracy.
