Isosiyete yacu imaze imyaka myinshi ikora ibikorwa byo gushonga bitumen. Ibikoresho bifite ibiranga gushonga byihuse, kurengera ibidukikije neza, nta asfalt imanika ingunguru, 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 ayahe mabwiriza tugomba gukurikiza mugihe dukora? Reka dusabe abatekinisiye babigize umwuga badufasha gusobanura:
1. Mbere yiki gikorwa, ibisabwa byubwubatsi, ibikoresho byumutekano bikikije, ububiko bwa asfalt, hamwe nibice bikoresha imashini ya melum ya bitumen, ibikoresho, pompe ya asfalt, nibindi bikoresho bikora bigomba kugenzurwa kugirango barebe niba ari ibisanzwe. Gusa mugihe nta kosa rishobora gukoreshwa mubisanzwe.
2. Igikuta cya asfalt kigomba kugira ifunguro rinini kuruhande rumwe na venti kurundi ruhande kugirango ingunguru ishobora guhumeka mugihe ushonga na asfalt ntabwo yakiriwe.
3.
4. Kumashini ya bitumen cyangwa ashyushye bitaziguye, ubushyuhe bugomba kuzamuka buhoro buhoro mugitangira kugirango asifalt itarenga inkono.
5. .
6. Ku mashini ya barrele ikoresha gaze yimyanda kugirango ikureho ingunguru, nyuma yuko ingunguru zose za asfalt zinjiye mucyumba cyo gukuramo, imyuka ihindura imyanda igomba 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. Kumashini ya barreling ishyuha kuburyo butaziguye 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.
