Description
Technical field
The utility model relates to a kind of scraper, especially relates to a kind of dynamic shear rheometer scraper.
Background technology
The general name of bond that asphaltic binder is pitch and is formed after mix various outer-penetrating agent in pitch, is widely used in field of road.Dynamic shear rheometer is that every stream change such as the complex modulus for asphaltic binder, phasing degree, Rutting parameter, tired factor index that U.S. SHRP plans to research and develop is tested, to characterize the test apparatus of asphaltic binder rheological characteristics.During test, diameter need be selected to be a pair of 25mm or 8mm circular upper lower plate (also known as parallel-plate) according to testing requirements.According to code requirement, diameter is should ensure that sheet separation is 1mm in process of the test after asphaltic binder sample placed by the parallel-plate of 25mm, diameter is the parallel-plate sheet separation of 8mm is then 2mm, and asphaltic binder sample edge and upper and lower plates edge all need to repair neatly before the test.
At the parallel-plate temperature of setting, the asphaltic binder sample of having cast is placed between parallel-plate, carries out instrumentation.According to code requirement, elected when to allocate andante diameter be 25mm, after making instrumentation, sheet separation is 1.050mm, has more bitumen samples carry out scraping to edges of boards, and then operating instrument makes gap be 1.000mm, tests; When selected parallel-plate diameter is 8mm, scraping when being 2.100mm in sheet separation, final gap is 2.000mm.
At present, the scraper that dynamic rheological property boxshear apparatus configures mostly is a wide about 2mm of handle, and the steel bar of the wide about 5mm in end, curves a right angle in end.Adopt this scraper to repair having more asphaltic binder sample between parallel-plate, when making asphaltic binder sample edge and upper and lower parallel-plate neat in edge, circular parallel-plate edge carries out scraping sample finishing to use position, right angle, scraper end to comply with.When this scraper scrapes sample to circular specimen edge, 3 ~ 4 times ability are at least needed substantially to scrape, reach asphaltic binder sample and parallel-plate neat in edge, so not only there is the deficiency of inefficiency, the parallel-plate edge simultaneously adopting straight ends to scrape circular arc does not match, and it is bad to scrape sample shape.In addition, when test temperature is lower, because of the thickness of asphaltic binder self, adopt cold scraper cannot repair asphaltic binder, after scraper need being heated on electric furnace, the scraper of heat is adopted to carry out finished edge, such complex operation, and scraper temperature can not be controlled very well, adverse effect be also result in the test of asphaltic binder sample.
