Bitumen kudziyisa matangi imhando yemidziyo yekugadzira migwagwa uye zvishoma nezvishoma yakashandiswa zvakanyanya. Sezvo iwo ari mahombe-zviyero zvekushandisa, zvinodikanwa kuti utarise kune yakakodzera kuchengetedzwa kwekushanda kana uchiishandisa. Ndeapi mabasa anofanirwa kuitwa mushure mekunge tangi yekudziya yebhitumini iripo? Nhasi ndichakutsanangurira zvakadzama:

Mushure mekunge bhitumini yekudziisa tangi yaiswa panzvimbo, ndapota tarisai kuti zvinongedzo zvakagadzikana uye zvakasimba, kana zvikamu zvekushanda zviri nyore, kana mapaipi akajeka, uye kana wiring yemagetsi yakarurama. Pakuisa bhitumini kekutanga, ndapota vhura vharuvhu yekuburitsa kuti bhitumini iende kuSmooth kuwana hita. Usati wapisa, tapota zadza tangi yemvura nemvura, svinura valve kuitira kuti mvura yemvura mujenereta yemhepo isvike kune imwe nzvimbo yakakwirira, uye uvhare valve.
Kana bhitumini yekudziya tangi ichiiswa mukushandiswa kwemaindasitiri, njodzi dzinogona kuitika uye kurasikirwa kunokonzerwa nekusashanda zvakanaka kunofanirwa kudzivirirwa kubva pazvinhu zvina: pre-kutanga kugadzirira, kutanga, kugadzira uye kuvhara. Usati washandisa bhitumini yekudziisa, tarisa mvura yetangi redhiziri, tangi remafuta anorema, uye tangi rebhitumini. Kana tangi ine 1/4 yemafuta, inofanira kuzadzikiswa nenguva, uye kuchengetedzwa kwevashandi nemidziyo yekubatsira munzvimbo imwe neimwe kunofanirwa kuve nechokwadi.
