Ngethuba lenkqubo yokwakhiwa kweeprojekthi zobunjineli bomhlaba, ngenxa yeemeko ezinzima zeeprojekthi, kukho iintlobo ezininzi zeengxaki ezinokuvela. Phakathi kwabo, isityalo sokuxuba i-asphalt sisixhobo esiphambili kwiprojekthi, ngoko kufuneka kunikwe ingqalelo eyaneleyo. Ngokuphathelele iingxaki ekusenokuhlangatyezwana nazo, makhe sihlolisise oko zikuko namhlanje.
Ngokusekelwe kumava amatyala okwakha kwilizwe lam kwiminyaka, ukusebenza kwesityalo sokuxuba i-asphalt kuya kuchaphazeleka kwizinto ezininzi. Ukuze kuphuculwe umgangatho weeprojekthi ze-asphalt, siya kudibanisa ezi mveliso kunye namava okwakha ukuhlalutya, ukufumana izizathu zeengxaki ezithile kwinkqubo yokwakha, kunye nokubonelela ngamava athile asebenzayo kuwo wonke umntu.
Ngokomzekelo, enye yeengxaki eziqhelekileyo zezixhobo zokuxuba i-asphalt kwinkqubo yokwakha yingxaki yomthamo wokuvelisa. Ngenxa yokuba le ngxaki iya kuchaphazela ngokuthe ngqo ixesha lokwakha kunye neminye imiba yeprojekthi, ifunyenwe ngokuhlalutya ukuba amandla okuvelisa angazinzanga okanye ukusebenza okuphantsi kwesityalo sokuxuba i-asphalt kunokuba nezizathu ezininzi, eziye zabelwa ngoku kunye nomntu wonke.

1. Ukulungiswa kwezinto ezikrwada ezingahambelani nenzululwazi. Imathiriyeli ekrwada linyathelo lokuqala kwimveliso. Ukuba imathiriyeli ekrwada ayilungiswanga ngokwesayensi, inokuchaphazela ulwakhiwo olulandelayo kwaye ibangele iingxaki ezinjengokuncitshiswa komgangatho wokwakha. Umlinganiselo wokuxutywa kodaka kukulawula umyinge wesanti kunye negrabile yokuthuthwa kwezinto ezibandayo. Kufuneka ilungelelaniswe ngokwemeko yokwenyani ngexesha lemveliso. Ukuba kufunyaniswe ukuba ukudibanisa akulunganga, uhlengahlengiso olufanelekileyo kufuneka lwenziwe ukuze kuqinisekiswe ukuveliswa kwesityalo sokuxuba i-asphalt.
2. Ixabiso lepetroli kunye ne-diesel ayanele. Ukuze kuqinisekiswe umgangatho wokwakha, umgangatho weoli yokutshisa kufuneka ukhethwe kwaye usetyenziswe ngokwemigangatho efunekayo. Kungenjalo, ukuba ukhetha iinjini zedizili eziqhelekileyo, iinjini zedizili ezinzima okanye ioyile yamafutha ngenxa yokubawa, iyakuchaphazela kakhulu amandla okufudumeza kwesomisi somoya kwaye ibangele ukuba isityalo sokuxuba i-asphalt sibe sezantsi kakhulu.
3. Ubushushu besondlo alulingani. Njengoko sonke sisazi, ubushushu bokutya bunokuba nempembelelo enkulu kumgangatho wesicelo semathiriyeli ekrwada. Ukuba iqondo lobushushu liphezulu kakhulu okanye liphantsi kakhulu, ezi zixhobo zingenakusetyenziswa ngokuqhelekileyo kwaye zibe yinkunkuma, engayi kudla kakhulu iindleko zemveliso yesityalo sokuxuba i-asphalt, kodwa ichaphazela imveliso yayo yemveliso.
