Abstract

The invention discloses an asphalt aging instrument which includes a material bench, and an electrode being connected to the material bench to drive the material bench. The rotation speed of the material bench is 15 +/- 0.2 r/min. The material bench is driven by a motor so that the material bench can be rotated at a constant rate, so that materials are irradiated and sprayed uniformly, thereby achieving a result having better scientificity.

Description

Ageing of asphalt instrument
Technical field
The present invention relates to field of mechanical technique, be specifically related to a kind of ageing of asphalt instrument.
Background technology
Pitch is the important materials in road construction, pitch aging/hardening has a significant impact the usability of pitch, is related to the serviceable life on road surface.Ageing of asphalt causes the moulding decline of pitch, and ductility deteriorates, finally loses use value, causes the reason of ageing of asphalt to mainly contain: the active transformation of material itself, sunshine impact, air oxidation, temperature variation, water and humidity effect.The method of current Asphalt Aging Study mainly contains unaccelerated aging method and simulation aging test.
The method of current simulation aging test has: oxygen absorbed method, inverse gas liquid chromatography, thin film oven method and rotary thin film in drying oven method (RTFOT) etc.
Rotary thin film in drying oven method (RTFOT) is proposed by Schmidt for 1973, the short ageing of simulation pitch mixing and stirring, in paving process.In RTFOT, asphalt film is exposed in air in the baking oven of 163 DEG C, forced draft in baking oven, asphalt membrane thickness is not at 0-3mm etc., liquid film flow, constantly changes in process of the test with the specimen surface of hot air, larger to the aging action of pitch, heated time is shorter, and code test continues 85 minutes.RTFOT test accuracy is high, favorable reproducibility, especially can give the burn-in effects of equal extent for different pitch.
But existing asphalt rotating thin-film oven material table maintains static, and causes test article light and non-uniform spraying like this, affects experimental result.
Summary of the invention
Technical matters to be solved by this invention is, provides a kind of ageing of asphalt instrument effectively overcoming prior art defect.
Technical scheme of the present invention is: ageing of asphalt instrument, comprises material table, it is characterized in that, an Electrode connection drives described material table.
An optimal technical scheme of the present invention, described material table revolution is at 15 ± 0.2 revs/min.
An optimal technical scheme of the present invention, described ageing of asphalt instrument uses accurate RTD sensor to carry out sampling to the temperature of operating room and is transferred to controller.
An optimal technical scheme of the present invention, is heat-insulation layer between the case shell of described ageing of asphalt instrument and operating room, and is filled with glass fibre in described heat-insulation layer.
Ageing of asphalt instrument provided by the invention adopts motor driving material table, makes it at the uniform velocity to rotate, causes material in uniform light, uniform spraying, make experimental result have more science.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1 is ageing of asphalt instrument structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the invention is described.One embodiment of ageing of asphalt instrument as shown in Figure 1, ageing of asphalt instrument, comprise outside case shell 2 and internal work room 1, it is heat-insulation layer 3 between case shell 2 and operating room 1, and be filled with glass fibre in heat-insulation layer 3, be provided with uviol lamp 4 and spray head 5 above in operating room 1, operating room 1 is provided with material table 6 close to bottom, and motor 7 connects this material table 6 of drive; And ageing of asphalt instrument of the present invention uses accurate RTD sensor to carry out sampling to the temperature of operating room is transferred to controller.
When opening ageing of asphalt instrument, (1), first power supply is started, heating " I " shelves are used during intensification, and set temperature controller to temperature required, when for reaching temperature required, changing heating " I " shelves is " 1/3 " or " 2/3 " gear, until be suspended on oven interior, a thermometer indicates temperature for " 163 ± 0.5 DEG C " balance;
(2), by test method, take a certain amount of bitumen samples, load reducing sample plasma bottle, be positioned on equably again on material table, when the bottle containing sample is less than 8, also empty bottle symmetry should be loaded onto, open switch, allow material table rotate according to certain speed, be preferably 15 ± 0.2 revs/min;
(3), start air compressor to baking oven air feed, after reaching the stipulated time, stop heating, rotating disk stall, then open the taking-up of operating room goalkeeper bottle.
More than show and describe ultimate principle of the present invention, principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not by the restriction of above-mentioned example; what describe in above-mentioned example and instructions just illustrates principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
