Nyob rau sab qaum teb lub caij ntuj no, asphalt Barrels khov rau hauv "cov roj ntsha" dej khov ", uas yog ib qho teeb meem uas muaj rau kev tsim kho cov tuam txhab. Cov qauv cua sov (xws li qhib nplaim taws ci thiab ncu ua kom yooj yim rau kev deformonization, thiab yaj kom yooj yim rau kev ua kom zoo nkauj, thiab yaj
Lub cim tshiab ntawmBITUMEN MELTING TSHUABAdopts ib-theem kev sib xyaw ua ke yaj kev thev naus laus zis:
Chreel Phab Ntsa Chav Pre-Melting: Spirting Chav Hluav Taws Xob 360 Degree li 15 feeb los soften cov dej khov nab kuab;
Txheej txheem cua sov infraration: tus carbon fiber infrared raj radiates txheej hauv 30 vib nas this, thiab hloov pauv kev ua kom zoo nkauj hauv qab daus;
Mechanical illation Icel
Raws li kev ntsuas tiag tiag, hauv qab -30 degree ib puag ncig, thiab lub zog siv tau txo los ntawm 30% piv nrog cov txheej txheem ib txwm muaj. Tom qab yaj, kev hloov pauv ntawm asphalt indexation nkag mus tsawg dua ± 3%, sib ntsib JTG f {{4 4 4 4. Lub me me melting tshuab yog nruab nrog qhov tsawg-kub pib ua kom muaj kev ua tau zoo, ua tiav qhov teeb meem ntawm asphalt Debiciencel hauv siab thiab chaw txias.
