Ngesikhathi sokwakhiwa kwamaphrojekthi wobunjiniyela bomhlaba, ngenxa yezimo eziyinkimbinkimbi zamaphrojekthi, kunezinhlobo eziningi zezinkinga ezingase ziphakame. Phakathi kwabo, isitshalo sokuxuba i-asphalt siyimishini eyinhloko kuphrojekthi, ngakho-ke kufanele inikezwe ukunakwa okwanele. Mayelana nezinkinga okungenzeka kuhlangatshezwane nazo, ake sibheke ukuthi ziyini namuhla.
Ngokusekelwe ekuhlangenwe nakho kwamacala okwakha ezweni lami phakathi neminyaka edlule, ukusebenza kwesitshalo sokuxuba i-asphalt kuzothinteka yizici eziningi. Ukuze sithuthukise ikhwalithi yamaphrojekthi we-asphalt, sizohlanganisa lezi zenzakalo zokukhiqiza nezokwakha ukuze sihlaziye, sithole izimbangela zezinkinga ezithile ohlelweni lokwakha, futhi sinikeze ulwazi oluthile olusebenzayo kuwo wonke umuntu.
Isibonelo, enye yezinkinga ezivame kakhulu zemishini yokuxuba i-asphalt ohlelweni lokwakha yinkinga yamandla okukhiqiza. Ngenxa yokuthi le nkinga izothinta ngokuqondile isikhathi sokwakha kanye nezinye izici zephrojekthi, kutholakala ngokuhlaziywa ukuthi umthamo wokukhiqiza ongazinzile noma ukusebenza kahle okuphansi kwesitshalo sokuxuba i-asphalt kungase kube nezizathu eziningana, manje ezabelwa wonke umuntu.

1. Ukulungiswa kwezinto ezingavuthiwe okungezona ezesayensi. Izinto ezingavuthiwe ziyisinyathelo sokuqala sokukhiqiza. Uma izinto zokusetshenziswa zingalungiswanga ngokwesayensi, kungase kuthinte ukwakhiwa okulandelayo futhi kubangele izinkinga ezifana nokuncipha kwekhwalithi yokwakha. Isilinganiso sokuxutshwa kodaka okuhlosiwe siwukulawula ingxenye yezinto zokuhamba zesihlabathi namatshe abandayo. Kufanele ilungiswe ngokuya ngesimo sangempela ngesikhathi sokukhiqiza. Uma kutholakala ukuthi inhlanganisela ayilungile, kufanele kwenziwe ukulungiswa okufanele ukuze kuqinisekiswe ukuphuma kwesitshalo sokuxuba i-asphalt.
2. Inani likaphethiloli likaphethiloli nodizili alanele. Ukuze kuqinisekiswe ikhwalithi yokwakhiwa, ikhwalithi yamafutha okushisa kufanele ikhethwe futhi isetshenziswe ngokuvumelana nezindinganiso ezidingekayo. Uma kungenjalo, uma ukhetha izinjini ezijwayelekile zikadizili, izinjini zedizili ezisindayo noma uwoyela kaphethiloli ngenxa yokuhaha, kuzothinta kakhulu amandla okushisa esomiso somoya futhi kubangele ukukhishwa kwesitshalo sokuxuba i-asphalt kube phansi kakhulu.
3. Izinga lokushisa lokuphakelayo alilingani. Njengoba sonke sazi, izinga lokushisa lokuphakelayo lingase libe nomthelela omkhulu kwikhwalithi yokusetshenziswa kwezinto zokusetshenziswa. Uma izinga lokushisa liphezulu kakhulu noma liphansi kakhulu, lezi zinto zokusetshenziswa zingase zingasetshenziswa ngokujwayelekile futhi zibe yimfucuza, okungeke nje kudle kakhulu izindleko zomkhiqizo wesitshalo sokuxuba i-asphalt, kodwa futhi kuthinte ukukhiqizwa kwayo.
