Isitshalo sokuxuba i-asphalt isethi ephelele yemishini yokukhiqiza ngobuningi bokhonkolo lwe-asphalt. Wonke umshini wezinto zokusebenza uqukethe amasistimu amaningi, njenge-batching system, isistimu yokomisa, isistimu yokuvutha, uhlelo lokuhlinzeka ngempushana kanye nohlelo lokuvimbela uthuli. Uhlelo ngalunye luyingxenye ebalulekile yesitshalo sokuxuba i-asphalt.

Isimo sokusebenza sesistimu yokushiswa kwesitshalo sokuxuba i-asphalt sinomthelela omkhulu kulo lonke uhlelo, oluhlobene nokusebenza kahle kwezomnotho kwesistimu yonke, ukunemba kokulawula izinga lokushisa kanye nezinkomba zokukhishwa kwegesi ye-flue. Lesi sihloko sizokwethula kafushane indlela yokwahlulela isimo sokusebenza sesistimu yokusha yesitshalo sokuxuba i-asphalt.
Ngokuvamile, ngenxa yobunkimbinkimbi bemishini nezindlela zokubona, azikho izimo ezingafinyelelwa ohlelweni lokusebenza lwezitshalo eziningi zokuxuba i-asphalt. Ngakho-ke, kulula kakhulu ukwahlulela isimo sokusebenza ngochungechunge lwezici ezinembile njengombala, ukukhanya nokuma kwelangabi. Le ndlela ilula kakhulu futhi iyasebenza.
Lapho isistimu yokusha yesitshalo sokuxuba i-asphalt isebenza, lapho uphethiloli uvutha ngokujwayelekile kusilinda esomisayo, umsebenzisi angakwazi ukubona ilangabi ngaphambili kwesilinda. Ngalesi sikhathi, isikhungo somlilo kufanele sibe phakathi kwe-cylinder yokomisa, futhi ilangabi lisakazwa ngokulinganayo nxazonke futhi ngeke lithinte udonga lwesilinda. Ilangabi ligcwele. Lonke uhlaka lwelangabi lucacile, futhi ngeke kube nomsila omnyama wentuthu. Izimo zokusebenza ezingavamile zesistimu yokuvutha zihlanganisa, isibonelo, ububanzi belangabi bukhulu kakhulu, okuzokwenza ukuthi i-carbon deposits enzima yakheke emgqonyeni wesithando somlilo futhi ithinte isimo sokusebenza esilandelayo sesistimu yokuvutha.
