Iphuzu lokuqala ukujwayela isiqondiso somugqa wendawo yokwakha, ngoba ibanga lokuhamba kwe-asphalt lithinta ngokuqondile ikhwalithi ye-asphalt, ngakho-ke lapho ukwakhiwa kwesiteshi sokuxuba inhlabathi ye-asphalt, kufanele kucatshangelwe ngokugcwele ukuhlangabezana ngokugcwele nezidingo ze-asphalt. indawo. Ukusatshalaliswa kwe-asphalt kufanele kuqinisekiswe ngokugcwele ngokusho kwemidwebo yokwakha ukuze kube lula indawo yesikhungo esiseduze sezitshalo zokuxuba i-asphalt.

Iphuzu lesibili ukuqonda nokuphatha kahle izici eziyisisekelo zokuxuba ukwakhiwa kwesiteshi, okuhlanganisa amanzi, ugesi kanye nendawo yaphansi; iphuzu lokugcina limayelana nendawo ezungezile yendawo yokwakha. Njengoba isikhungo sokuxuba itiyela siyisisekelo sokucubungula esinezinga eliphezulu lokwakhiwa kwemishini, ukungcola okunjengothuli nomsindo kuzoba kubi kakhulu. Lokhu kudinga ukuthi lapho sikhetha isiza, kufanele sizame ukugwema izindawo zokuhlala, izikole, izindawo zokuzalela nezinye izindawo lapho kugxilwe khona abantu nemfuyo, ukuze sinciphise umthelela wendawo ezungezile ngangokunokwenzeka.
