Izixhobo zezityalo zokuxuba i-asphalt zidibana neengxaki ezahlukeneyo, kwaye iindlela zokuphatha kunye nokusombulula nazo zihluke. Ngokomzekelo, enye yeengxaki eziqhelekileyo zezixhobo zokuxuba i-asphalt kukuba iindawo zidiniwe kwaye zonakaliswe. Ngeli xesha, indlela ekufuneka yenziwe ngabavelisi kukuqala kwimveliso yamalungu.

Abavelisi bezixhobo zezityalo zokuxuba i-asphalt banokuphucuka ngokuphucula umphezulu wokugqitywa kwamalungu, okanye ngokwamkela ukuhluza okuphakathi kwecandelo elinqamlezayo ukufezekisa injongo yokunciphisa uxinzelelo lwamalungu. I-Carburizing kunye nokucima kungasetyenziselwa ukuphucula ukusebenza kwezixhobo zokuxuba i-asphalt. Ezi ndlela zinokunciphisa umphumo wokukhathala kunye nokulimala kwamalungu.
Ukongeza kokudinwa kunye nokulimala kwamalungu, izityalo zokuxuba i-asphalt nazo ziya kuhlangabezana nemeko yeendawo zomonakalo obangelwa kukungqubana. Ngeli xesha, abavelisi kufuneka bazame ukusebenzisa izinto zokunxiba, kwaye kwangaxeshanye, kufuneka bazame ukunciphisa amathuba okungqubana xa kuyilwa imilo yezixhobo zokuxuba i-asphalt. Ukuba isixhobo sidibana nomonakalo obangelwe kukuhlwa, ngoko ke abasebenzisi banokusebenzisa imathiriyeli ekwaziyo ukutyiwa njengechromium kunye ne-zinc ukubeka umphezulu wamalungu esinyithi. Le ndlela inokuthintela ukubola kwamalungu.
