Hariho kandi valve isubira inyuma mu ruganda rwa Asfalt, muri rusange ntabwo itera ibibazo, ntabwo rero numvise ibisubizo byayo birambuye mbere. Ariko muburyo bufatika, twahuye nubukira. Tugomba kubyitwaramo dute?

Kunanirwa kwa valve yo gusubiramo ibihingwa bya asfalt ntabwo bigoye, ni ukuvuga ko hasubirwamo ibintu bitangiye, nibindi bikaba byananiranye nibitekerezo birumvikana bitandukanye. Kugirango udusimba dusubiremo kutahindura icyerekezo mugihe, muri rusange biterwa n'amavuta make, mu mpeshyi iratanga cyangwa yangiritse, umwanda cyangwa umwanda wangiritse cyangwa umwanda cyangwa umwanda. Viscosity, nibiba ngombwa, amavuta cyangwa ibindi bice birashobora gusimburwa.
Nyuma yo gukoresha igihe kirekire, valve yo guhinduranya ikunda kwambara ingenzi ya valve impeta ya valve, ibyangiritse kuri valve stem hamwe nintebe ya valve, bikavamo imirongo ya gaze muri valve. Muri iki gihe, impeta ya kashe, valve stem nintebe ya valve igomba gusimburwa, cyangwa valve isubira inyuma igomba gusimburwa muburyo butaziguye. Kugirango ugabanye igipimo cyo gutsindwa kwa asfalt, kubungabunga bigomba gukomera buri munsi.
