Iterambere ry’umuryango, igihugu cyita cyane ku iyubakwa ry’ibikorwa bya komini. Kubwibyo, nkibikoresho byingenzi mugutezimbere no kubaka ibibazo bya komini, ibihingwa bivanga asfalt bigenda byamamara kandi inshuro zikoreshwa biriyongera. Kuvanga ibihingwa bya asfalt bizahura namakosa menshi cyangwa make mugihe cyo kuyakoresha. Iyi ngingo irerekana muri make uburyo bwo gukemura amakosa ya reveri ihindagurika mu gihingwa kivanga asfalt.

Niba hari ikibazo kijyanye no gusubira inyuma mumashanyarazi avanze na asfalt, kwigaragaza cyane cyane ko valve idashobora guhindurwa cyangwa ibikorwa byo gusubira inyuma biratinda. Hashobora kubaho kandi imyuka ya gaze, gutsindira amashanyarazi ya electromagnetic, nibindi. Muri rusange, iyo uhuye nikibazo nkicyo, ikintu cya mbere ugomba gusuzuma ni ugushakisha intandaro yamakosa, kugirango amakosa akurweho neza kandi neza.
Niba valve isubira inyuma idashobora guhindurwa cyangwa ibikorwa byo gusubira inyuma biratinda, uyikoresha arashobora gusuzuma impamvu nko gusiga amavuta nabi, kuvomera amasoko, cyangwa umwanda wamavuta uhuza ibice byanyerera. Muri iki gihe, uyikoresha arashobora kubanza kugenzura igikoresho cyamavuta kugirango agenzure aho akora, hanyuma akemeza ubwiza bwamavuta yo gusiga. Niba hari ikibazo kibonetse cyangwa ni ngombwa, amavuta yo gusiga cyangwa isoko arashobora gusimburwa.
Kumeneka gazi mubisanzwe biterwa no guhinduranya valve yuruganda ruvanga asfalt rukora kumurongo mwinshi mugihe kirekire, ibyo bigatuma kwambara impeta ya kashe ya kashe nibindi bice. Niba kashe idakomeye, kumeneka gaze bizaba bisanzwe. Muri iki gihe, impeta ya kashe cyangwa igiti cya valve nibindi bice bigomba gusimburwa.
