Isosiyete yacu ifite uburambe bwimyaka myinshi mugukora ibikoresho bya biutmen decanter. Ibikoresho bifite ibiranga kuvanaho ingunguru byihuse, kurengera ibidukikije neza, nta barrale yimanitse kuri asfalt, guhuza n'imihindagurikire y'ikirere, kubura umwuma mwiza, gukuraho ibyuma byikora, umutekano no kwizerwa, no kwimuka byoroshye.

Nyamara, asfalt nigicuruzwa cyo hejuru cyane. Iyo bimaze gukorwa nabi, biroroshye cyane gutera ingaruka zikomeye. None ni ubuhe buryo tugomba gukurikiza mugihe dukora? Reka dusabe abatekinisiye babigize umwuga badufasha gusobanura:
1. Mbere yiki gikorwa, ibisabwa byubwubatsi, ibikoresho byumutekano bikikije, ingano yububiko bwa asfalt, nibice bikora, ibikoresho, pompe ya asfalt, nibindi bikoresho byakazi byimashini ikuramo ingunguru bigomba kugenzurwa kugirango barebe niba ari ibisanzwe. Gusa mugihe nta kosa rishobora gukoreshwa mubisanzwe.
2. Igikuta cya asfalt kigomba kugira ifunguro rinini ku mpera imwe n’umuyaga ku rundi ruhande kugira ngo ingunguru ishobore guhumeka igihe ingunguru yakuweho kandi asfalt itanyoye.
3.
4. Kumashini ya diyanteri ya tubut cyangwa yashyutswe neza, ubushyuhe bugomba kuzamuka buhoro buhoro mugitangira kugirango asifalt itarenga inkono.
5. .
6. Kuri mashini ya decuter ya biutmen ikoresha gaze yimyanda kugirango ikureho ingunguru, nyuma yuko ingunguru zose za asfalt zinjiye mucyumba cya barriel, icyerekezo cyo guhindura imyanda kigomba guhindukirira kuruhande rwicyumba. Iyo ibibari byubusa bikururwa bikuzuzwa, imyanda ihindura imyanda igomba guhindukirira kuruhande rugana kuri chimney.
7. Iyo ubushyuhe bwa asfalt mucyumba cya asfalt bugeze hejuru ya 85 ℃, pompe ya asfalt igomba gufungurwa kugirango izenguruke imbere kugirango yihutishe ubushyuhe bwa asfalt.
8. Kubimashini ya decuter ya biutmen ishyushya bitaziguye ubushyuhe bwubushakashatsi, nibyiza kutavoma asfalt yakuwe mubice bya barrique ya asfalt, ahubwo ikagumya kuba asfalt kugirango izenguruke imbere. Mu bihe biri imbere, umubare runaka wa asfalt ugomba kugumana igihe cyose pompe ivomwe, kugirango asfalt ikoreshwe hakiri kare mugihe cyo gushyushya. Pompe ya asfalt ikoreshwa mukuzenguruka imbere kugirango yihutishe gushonga no gushyushya asfalt.
