Ibimera bivanze bya Ashalt bigizwe na sisitemu nyinshi, buri kimwe kifite imirimo itandukanye. Sisitemu yo gutwika nurufunguzo rwo gukora ibikoresho kandi rugira ingaruka zikomeye kumurimo n'umutekano wibikoresho. Muri iki gihe, hashobora gukoresha sisitemu yo gutwika gaze, ariko iyi sisitemu ihenze kandi ntabwo ikwiriye ibigo bimwe.

Kubushinwa, sisitemu yo gutwikwa ikoreshwa irashobora kugabanywamo uburyo butatu, aribyo amakara, ashingiye kuri peteroli na gaze. Noneho, hamwe na sisitemu, hari ibibazo byinshi byingenzi, harimo cyane cyane ko ivu ryarimo ifu yamakara ni ibintu bidakamba. Byatewe na sisitemu yo gushyushya igihingwa cya asfalt, ibyinshi mu ivu binjira mu mva ya Asfalt. Byongeye kandi, ivu ni acide, izagabanya neza ubwiza bwimvange ya asfalt, idashobora kwemeza ubuzima bwa serivisi yibicuruzwa bya Asfalt. Mugihe kimwe, ifu yamakara iratwika buhoro, biragoye rero gutwika byimazeyo mugihe gito, bikavamo imikoreshereze yo gupima bike ningufu.
Ntabwo ari uko, niba amakara akoreshwa nka lisansi, umusaruro wukuri ushobora kugerwaho kubikoresho gakondo bikoreshwa mubikorwa byo gutunganya ni bike, bigabanya neza umusaruro wubuvanze. Byongeye kandi, gutwikwa ifu yamakara mu bimera bya asfalt bisaba icyumba kinini, hamwe nibikoresho byongirika mucyumba cyo gutwika ni ibikoresho byo kwibasirwa no gusingwa buri gihe kandi bikaba ari hejuru.
Noneho, niba gaze ikoreshwa nkibikoresho fatizo, igipimo cyo gukoresha cyane gishobora kugerwaho. Sisitemu yo gutwika irahuze kandi irashobora kuzigama umwanya munini. Ariko, gahunda yo gutwika ibihingwa byo kuvanga Asfalt byatewe na gaze nayo ifite amakosa menshi. Ikeneye guhuzwa numuyoboro wa gazi karemano, kidakwiriye ibihe bikeneye kuba mobile cyangwa akenshi bigomba kwimurwa. Byongeye kandi, niba umuyoboro wa gazi karemano uri kure, bizatwara amafaranga menshi kugirango ushireho indangagaciro kandi ushireho imiyoboro n'ibindi bikoresho bifasha.
Noneho, tuvuge iki kuri sisitemu yo gutwika ikoresha amavuta ya lisansi nka lisansi? Sisitemu ntishobora kubika umusaruro gusa, ariko kandi byoroshye kugenzura ubushyuhe bwa peteroli. Sisitemu yo gutwika ibimera bya ashalt byatewe n'amavuta ya lisansi ifite inyungu zubukungu, kandi irashobora kandi kubona ubushobozi bwo gutwika mugucunga amavuta ya lisansi.
