Kwiinkalo ezininzi ezahlukeneyo, iimfuno zokhuseleko lokusingqongileyo zingqongqo kakhulu kule mihla. Izikhululo zokuxuba eziqhelekileyo zinokuhlangabezana njani neemfuno zokhuseleko lokusingqongileyo? Oku kuye kwaba yinkxalabo kwiinkampani ezininzi zezikhululo zokuxuba. Ukuba iinkampani zokuvelisa ezifana nezikhululo zokuxuba i-asphalt ziphuculwe ngokufanelekileyo ekukhuselweni kwendalo, aziyi kuphucula kuphela ukuveliswa kwekhonkrithi ye-asphalt, kodwa nokunciphisa impembelelo yokungcola kwendalo. Ke ngoko, ukuphuculwa kokhuseleko lokusingqongileyo kube ngomnye wemisebenzi ebalulekileyo yokuxuba izitishi.

Namhlanje, iinkampani ezininzi zincamathela ukubaluleka kokugcina amandla kunye nokunciphisa ukusetyenziswa kunye nemveliso eluhlaza. Kwimveliso yekhonkrithi ye-asphalt yangoku, izikhululo zokuxuba zibe likhonkco elibaluleke kakhulu. Xa isikhululo sokuxuba sivelisa izinto eziluhlaza zekhonkrithi, ungcoliseko oluninzi olwahlukeneyo lunokwenzeka. Kule ngxaki, kuya kuchaphazela imveliso eqhelekileyo kunye nokuveliswa, ngoko ke kuyimfuneko ukulungisa ngokufanelekileyo indawo yonke. Phakathi kwazo, ingxolo, ungcoliseko lwamanzi kunye nongcoliseko lothuli zizo zonke iingxaki ezibalaseleyo zokungcoliseka kwendalo kwizikhululo zokuxuba i-asphalt.
Emva kokufumana izinto eziphambili zokungcoliseka kwendalo, sinokuguqula ngempumelelo kwaye siphucule iingxaki ezithile. Phakathi kwabo, ungcoliseko lwengxolo yingxaki enzima ngakumbi ukujongana nayo, ngoko ke kufuneka sikhethe isicwangciso esisebenzayo sokuphucula ukwenza inguqu nokulawula ingxolo kwindawo yokusebenzela evaliweyo. Oku kuya kunciphisa ngempumelelo ingxolo eyenziwa yimveliso yezixhobo. Ngexesha elifanayo, ukulawulwa kwamanzi amdaka kunye nokunyangwa kwenkunkuma kuyimisebenzi ephambili, ngaloo ndlela ukubonelela ngeziqinisekiso ezisebenzayo zokwakhiwa kwesimanje.
