Inkqubo yokomisa kunye nokufudumeza inokuthathwa njengenxalenye ebalulekileyo kuyo yonke into, ngoko ke kumsebenzi wangempela, icubungula izinto ngendlela yokufudumala, ngaloo ndlela ikhuphe ngokupheleleyo i-aggregate ebandayo kwaye ifudumale ngexesha elifanayo. kwiqondo lokushisa elithile, ngaloo ndlela ukubonelela ngeemeko eziyimfuneko ekusebenzeni okuqhelekileyo kunye nokuqhubekayo kwesityalo sokuxuba i-asphalt.
Ngethuba lonke inkqubo yokufudumala kwezityalo zokuxuba i-asphalt, injongo ephambili kukwenza ukusebenza komxube ngokuhambelana neemfuno zokusetyenziswa, kunye nokunceda izinto ezigqityiweyo zibe nokusebenza kakuhle kwe-paving. Ngokwesiqhelo, ubushushu bobushushu be-aggregate bumalunga noluhlu lwe-160℃-180℃.
Inkqubo yokumisa kunye nokufudumeza kwesityalo sokuxuba i-asphalt ngokuyinhloko iqukethe iinxalenye ezimbini: idramu yokumisa kunye nesixhobo sokutshisa. Igubu lokomisa ubukhulu becala sisixhobo esigqibezela ukomiswa nokufudumeza okubandayo kunye nokumanzi. Ukuze i-aggregate ebandayo-emanzi ikwazi ukugqiba iimfuno ezintathu zokufudumeza, ukuphelelwa ngamanzi emzimbeni, ukomisa kunye nokufudumeza ngexesha elithile, akuyimfuneko kuphela ukusabalalisa ngokulinganayo i-aggregate kwi-drum, kodwa kunye nokubonelela ngokwaneleyo. ixesha lokusebenza, ngale ndlela kuphela ubushushu bokukhutshwa kwesityalo sokuxuba i-asphalt sifikelela kwiimfuno ezichaziweyo.
Isixhobo sokutshisa isityalo sokuxuba i-asphalt sisetyenziselwa ukubonelela ngomthombo wokushisa womisa kunye nokufudumeza i-aggregate ebandayo. Oko kukuthi, ngaphezu kokukhetha i-fuel efanelekileyo, kuyafuneka ukuba ukhethe isitshisi esifanelekileyo kwisityalo sokuxuba i-asphalt. Ukuze kuqinisekiswe umphumo wokufudumeza kwesityalo sokuxuba i-asphalt, ngaphezu kokukhethwa ngokufanelekileyo kwezi zixhobo zimbini zingentla, amanyathelo athile okufakelwa nawo kufuneka athathwe.
Ngenxa yokuba inkqubo yokuxuba i-asphalt, kuphela ngokuqinisekisa ukusebenza okuqhelekileyo kwenkqubo yokufudumala sinokunika isiqinisekiso sokusebenza kwenkqubo yonke, ukubonelela ngesiseko esiyimfuneko kwimveliso elandelayo, kwaye sihlangabezane neemfuno zokuvelisa isityalo sokuxuba i-asphalt.
