Kubera ko ibikoresho byo kuvanga asfalt byakoreshejwe byaguzwe hakiri kare, sisitemu yo gutwika no kumisha 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, abakoresha bizeye ko byakemurwa no guhindura sisitemu yo gutwika ibikoresho bivanga asfalt. Ni ibihe bisubizo bifatika abahanga bafite kuri ibi?
Guhindura sisitemu yo gutwika ibikoresho bivanga asifalt ahanini birimo ibintu bikurikira. Iya mbere ni ugusimbuza ibikoresho byo gutwika, gusimbuza imbunda yambere ya mazutu ya spray ya mazutu hamwe ninshingano ziremereye na mazutu zibiri-ntego. Iki gikoresho ni kigufi kandi ntigisaba guhinduranya insinga zishyushya amashanyarazi. Icyangombwa nuko itazahagarikwa namavuta aremereye asigaye, bigatuma amavuta aremereye yatwikwa burundu 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 iyambere yari itanura ryamavuta yumuriro wa mazutu, kandi noneho ryasimbujwe itanura ryamavuta yumuriro wumuriro, rishobora kuzigama cyane ibiciro.
