Oomatshini bokwakhiwa kweendlela luhlu olukhulu, ngoko makhe sithethe ngenye yazo, isityalo sokuxuba i-asphalt. Isetyenziselwa ikakhulu ukuvelisa i-asphalt, ngoko ke kubaluleke kakhulu phakathi koomatshini bokwakha iindlela kunye nezixhobo. Inxalenye ebalulekileyo, ukuba umgangatho wemveliso ogqityiweyo awulungile, uya kuchaphazela kakhulu umgangatho wendlela. Ke ngoko, ngezantsi, umhleli uya kusebenzisa uhlobo lombuzo kunye nempendulo ukukukhokela ukuba uqhubeke nokufunda.

Umbuzo 1: Ngaba i-asphalt ye-petroleum inokusetyenziswa ngokuthe ngqo kwizityalo zokuxuba i-asphalt?
Oku kunokwenzeka ngokupheleleyo, kwaye kunokusetyenziswa njengento ekrwada ukuvelisa iimveliso ezintsha ze-asphalt.
Umbuzo 2: Isityalo sokuxuba i-asphalt kunye nesityalo sokuxuba ikhonkrithi ye-asphalt, ngaba kukho umahluko phakathi kwabo?
Akukho mahluko phakathi kwesityalo sokuxuba i-asphalt kunye nesityalo sokuxuba ikhonkrithi ye-asphalt. Ziyafana, kodwa le yokugqibela inegama lobuchwephesha.
Umbuzo 3: Kweyiphi indawo yesixeko?
Oomatshini bokwakha iindlela ezifana nezikhululo zokuxuba i-asphalt zihlala zihlala ngaphandle kwezixeko, ubuncinci kude neendawo zasezidolophini.
