Background technology
The ductility of bitumen for road use be by regulation speed and at a temperature of, stretching standard specimen two ends until fracture
Length.Pitch low-temperature ductility is in close relations with cold cracking property, and therefore low-temperature ductility is a weight in China's design asphalt
Want index.
When preparing bitumen ductility sample, first, by interleaving agent uniform mixing, it is applied to the die trial base plate and two of clean dried
The inner surface of individual side form, and die trial is properly installed on die trial base plate；Then, pitch is come and gone from one end of die trial to the other end
For several times slowly in injection mould, slightly higher than die trial；Then, test specimen cools down at room temperature no less than 1.5h, is then struck off with hot scraper
Exceed the pitch of die trial, so that bituminous sheaths is flushed with die trial face；Finally, die trial is placed into the water of regulation test temperature together with base plate
It is incubated 1.5h in groove.Currently, common scraper is our putty knifes at ordinary times, is needed on electric furnace or alcolhol burner using front again
Heating, which is more dangerous and temperature should not control, the bitumen samples surface also out-of-flatness scraping, and have impact on bitumen ductility examination
Test result.Meanwhile, scraping mold process, due to end mould, side form and die trial base plate independently, easily making bitumen samples and die trial
Between produce gap, impact result of the test accuracy.

Side, its end is connected with pulley 14.
Described in the utility model be easy to cut the bitumen ductility die trial scraping sample, described two ends mould 1 is symmetricly set on glass
On the length direction of die trial detent 5 in glass plate 4, two side forms 2 are arranged on the die trial detent 5 on glass plate 4
On width；
Described in the utility model be easy to cut the bitumen ductility die trial scraping sample, the thickness of described blade 8 is 5mm, and it is wide
Spend Mould Breadth degree of having a competition and go out greatly more than 3cm.
Compared with prior art, the test dress of simulation bituminous paving sensing quick heating self-healing described in the utility model
Put and test method has the advantage that
1) upper surface of glass plate is provided with die trial detent, it is to avoid scraping mold process, due to end mould, side form and
Glass plate independently, produces gap it is ensured that the accuracy of result of the test between the bitumen samples causing and die trial；
2) blade temperature is uniform and stable and be conveniently adjusted, by the coordination work of controller, temperature sensor and heater
Make, blade temperature can be set, heater is by temperature conduction to blade；
3) pass through to arrange leveling bar in the handle both sides of temperature control scraper, and leveling bar is passed through the rail on pulley and glass plate
Road connects, thus keeping blade in the position level of surface of test piece, also ensure that to cut and scraping the smooth of rear surface of test piece.
