Isitshalo sonke sokuxuba i-asphalt sihlanganisa ithangi lokushisa, futhi ikhwalithi yomkhiqizo wokugcina ihlobene eduze nokusetshenziswa okulungile kwethangi lokushisa i-bitumen. Okulandelayo yizicaciso ezithile zokusebenza zesithenjwa sakho.
Enkambweni yokusebenzisa amathangi okushisa i-bitumen, kubalulekile ukunaka inqubo yayo yokuhlanza, okungafanele yenziwe kuphela njalo, kodwa futhi ilandele ngokuqinile inqubo. Okokuqala sebenzisa izinga lokushisa elingaba ngu-150 degrees ukuthambisa itiyela futhi ulikhiphe, bese usebenzisa i-ejenti yokuhlanza ukukhanya ukuze ususe ngokuphelele izingxenye ezisele odongeni lwemishini.

Ngaphandle kokuhlanza, izinga lokushisa libuye libe yisihluthulelo sokusebenzisa amathangi okushisa i-bitumen. Kunezidingo ezithile zokushisa. Uma kucatshangelwa ukuthi izakhiwo zamakhemikhali zebitumen ngokwazo zizwela kakhulu ekushiseni, lapho izinga lokushisa lingaphezu kuka-180 ° C, i-asphaltene ibola ibe Imvula yamahhala ye-carbon, i-carbides ne-asphaltene izothinta kakhulu i-ductility kanye nokunamathela kwebitumen, ukuwohloka kwezakhiwo. nokusebenza kwetiyela. Ngakho-ke, izinga lokushisa lokushisa nokusebenza kwe-bitumen yokushisa ithangi kufanele ilawulwe ngokuqinile lapho lishisa. isikhathi sokushisa.
