Kugirango ibikorwa byiza bya bitumen bitanga ibikoresho no kwagura ubuzima bwa serivisi, buri gihe no gusana birakenewe. Ibikurikira ni intambwe zihariye zo gusana no gusana:

Icya mbere, birakenewe guhora ugenzura ibice bitandukanye bya bitumen, harimo gutoranya ibintu bitandukanye bya bitumen, harimo gushyushya ibintu byatumen, harimo gushyushya ibintu, imiyoboro, indangagaciro, nibindi, kugirango byambarwa cyangwa byangiritse. Niba hari ibibazo byabonetse, bigomba gusanwa cyangwa gusimburwa ako kanya.

Mubikorwa nyabyo nubuzima, akenshi duhura nibibazo bitunguranye. Iyo ibyo bibazo bitunguranye bibaye, twakagombye dute? Kurugero, niba sitasiyo yo kuvanga Asfalt mu rugendo gitunguranye mugihe cyakazi, biragaragara ko bigira ingaruka ku iterambere ryimirimo yose. Niba bidafashwe neza, birashobora gutera ingaruka zikomeye.

Abstract: Ibikoresho byo kubohora bitun ni kimwe mu bikoresho byingenzi mukubaka ikirere. Igikorwa cyacyo nyamukuru nukushyushya byinshi byubukonje na butumen kugeza ubushyuhe bukwiye bwakazi ahazubakwa. Ibikoresho bya bitumen birashobora guteza imbere cyane imikorere yubwubatsi, kugabanya ibikoresho nigihe cyabantu, kandi urebe neza imiterere yumuhanda.

Turashimira umurimo utoroshye w'abakozi amanywa n'ijoro, ibihingwa bya bitumen byategetse n'umukiriya wa Vietnam byoherejwe nkuko byateganijwe uyu munsi! Kuvugisha ukuri, kubijyanye nubu buryo, wavuga ko atari byiza kandi byiza bishonga nibikoresho byubwubatsi byingenzi byubaka umuhanda kugeza ku bushyuhe bukwiye bwo kubaka. Irashobora gutanga ibisubizo byizewe kugirango utume kubaka umuhanda neza kandi byoroshye. Ihame ryakazi ryibi bikoresho ni ugushyushya biturungano kugeza ku bushyuhe bukwiye binyuze mu bushyuhe, hanyuma dutwara bitum bishyushye kugeza aho byubaka binyuze muri gahunda yo kubaka.

Mu mishinga yo kubaka umuhanda, imikorere yibiti bya ashalt ntabwo bifite akamaro. Muri iki gihe, hamwe n'imbaraga zubumenyi n'ikoranabuhanga, imirimo y'ibikoresho nayo iba byinshi. Kubwibyo, abakora bireba nabo bagomba gukomeza kuzamura ubumenyi bwabo bwo gukora no gutuza imirimo y'ibikoresho.

Asfalt nigikoresho gikoreshwa mubice bikunze gukoreshwa mumuhanda mugihugu cyanjye, gifite ingaruka runaka kubyemera nibyiza byimishinga yumuhanda. Nkibikoresho byingenzi byumuhanda utanga ibikoresho, icyifuzo cyo gukoresha ni hejuru, gifasha ingaruka rusange. Ibimera bivanga bya Ashalt nibikoresho byingenzi byingenzi mugihe bitanga kandi ukoresheje ibicuruzwa nkibi.
