Kubera ko uruganda ruvanga asfalt rwakoreshejwe rwaguzwe hakiri kare, sisitemu yo gutwika no gukama irashobora gusa kuzuza ibisabwa kugirango umuriro wa mazutu. Nyamara, uko igiciro cya mazutu cyiyongera, imikorere yubukungu yo gukoresha ibikoresho iba mike kandi ikamanuka. Ni muri urwo rwego, abayikoresha bizeye ko gishobora gukemurwa no guhindura uburyo bwo gutwika ibimera bivangwa na asfalt. Ni ibihe bisubizo bifatika abahanga bafite kuri ibi?
Guhindura uburyo bwo gutwika ibimera bivangwa na asfalt bikubiyemo ahanini ibi bikurikira. Iya mbere ni ugusimbuza ibikoresho byo gutwika, gusimbuza imbunda ya mazutu yambere ya mazutu ya spray hamwe ninshingano ziremereye na mazutu ebyiri-ya spray. Iki gikoresho ni kigufi kandi ntigisaba guhinduranya insinga zishyushya amashanyarazi.

Icyangombwa nuko itazahagarikwa namavuta aremereye asigaye, bigatuma amavuta aremereye yatwikwa rwose kandi bikagabanya ikoreshwa ryamavuta aremereye.
Intambwe ya kabiri ni uguhindura ikigega cya mazutu cyabanjirije hanyuma ugashyira igiceri cyamavuta yumuriro munsi yikigega kugirango gishobore gukoreshwa mu gushyushya amavuta aremereye kubushyuhe bukenewe. Muri icyo gihe, hagomba gushyirwaho akanama gashinzwe kugenzura amashanyarazi atandukanye kugira ngo sisitemu yose imenye guhinduranya byikora hagati ya mazutu n'amavuta aremereye, no kurinda sisitemu hamwe n'impuruza zumvikana kandi zigaragara.
Ikindi gice ni ugutezimbere itanura ryamavuta yumuriro, kubera ko itanura ryamavuta yumuriro yatwitse mazutu yakoreshejwe mbere. Kuriyi nshuro, yasimbujwe itanura ryamavuta yumuriro yumuriro, rishobora kuzigama cyane ibiciro.
