The chamber door 102 of temperature automatically controlled case is fixed on casing 101 by the door hinge 108 of side, holds door knob 104 outside Drawing can be opened it, and operating desk 14 can be slided along the bottom slide track 15 of casing 101, and pulling operation platform 14 tries Asphalt Penetration Test instrument to be put into temperature automatically controlled case 1, its power line connects external power source, water-bath by the reserved power supply string holes 109 on casing 101 The water inlet pipe of system is connected by the water inlet pipe preformed hole 110 on casing 101 with the circulator bath upper hose 9 drawn from water tank 4, The return pipe of water-bath system passes through the return pipe preformed hole 111 on casing 101 and the circulator bath return pipe 10 from the extraction of water tank 4 Connection.After all connecting, chamber door 102 is shut.
Start split-type air conditioner, heating-up temperature is set as 25 DEG C by air-conditioner controller 5, regulation air intake duct 6 and blast pipe 7 With the flow control valve 20 on the connecting line of split-type air conditioner indoor set group 3,4 temperature sensor 16- in casing 101 19 temperature datas passed back reach 25 DEG C;
Chamber door 102 is opened, pulling operation platform 14 before asphalt penetrometer power supply is connected, observes the water on table top Bulb apparatus, adjusts the level of asphalt penetrometer, and clean standard pin connector is put and loads connection after standard test weight Bar and fixation.Bitumen samples are put into cleansing bath tub, are watered that (water surface should not have specimen surface 10mm on request in cleansing bath tub More than), it is placed on the platform of asphalt penetrometer, operating desk 14 is pushed into casing 101, shuts chamber door 102.
Water pump 11 is opened, the water in water tank 4 is entered the water-bath of asphalt penetrometer by circulator bath upper hose 9 In system water inlet pipe, and the formation circulation waterway of water tank 4 is returned to through circulator bath return pipe 10;Open asphalt penetrometer Power switch, the temperature according to needed for being set test requirements document is 25 DEG C, and timing is 5s, treats temperature and water in casing 101 Temperature in bathtub is reached after test determination temperature, and the plug-type luffer boards in the both sides of casing 101 are opened, expose fixed luffer boards, are tried Test personnel by hand from both sides fix luffer boards in gathering hole in stretch into casing 101 and operated, ensured by elastic seal ring Seal in casing 101.
To be moved in the mobile bar of needle penetration display topmost, then will be equipped with the pin connecting rod of standard test weight also on move to most Upper end.Head is adjusted with coarse adjustment knob, makes standard needle tip from specimen surface about 10mm.Then it is slowly downward with vernier knob again Mobile standard pin, makes needle point be loosed one's grip when just having touched the surface of sample.Observation caliber pin can use logical when being contacted with specimen surface The external display 107 being connected with high-definition camera 106 is crossed to observe.
Needle penetration display is opened, it should be " mm-- millimeters " to reexamine the display unit of display, gently press needle penetration The mobile bar of display makes the upper end plane contact of its lower end and pin connecting rod, then presses the reset button of needle penetration display, It is zero to make display reading.
After the temperature stabilization of cleansing bath tub is to design temperature, by the "start" button on guidance panel, electromagnetic actuation makes mark In quasi- pin free-falling, injection bitumen samples, reach after the defined time, electromagnet, which is released, locks standard pin, standard pin Stop movement.
Gently pressing the mobile bar of needle penetration display makes the upper end plane contact of its lower end and pin connecting rod, now display Reading be exactly this experiment penetration number.
Same sample is repeated three times.Distance, the distance at testing site to planchet edge of each testing site all must not Less than 10mm.All before experiment sample constant temperature in water bath with thermostatic control should every time determined for a period of time, every time will use clean pin. When needle penetration is more than 200, at least with three pins, the pin of each experiment is stayed in the sample, again will when three pins have been pricked Pin takes out from sample.Pin can be removed and be continuing with after being cleaned with suitable solvent when needle penetration is less than 200.
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited thereto, Any one skilled in the art the invention discloses technical scope in, technique according to the invention scheme and its Inventive concept is subject to equivalent substitution or change, should all be included within the scope of the present invention.
