Inqaku lokuqala kukuba uqhelane nesalathiso somgca wendawo yokwakha, kuba umgama wokuthutha we-asphalt uchaphazela ngokuthe ngqo umgangatho we-asphalt, ngoko ke xa ukwakhiwa kwesikhululo sokuxuba umhlaba we-asphalt, kufuneka kuqwalaselwe ngokupheleleyo ukuhlangabezana ngokupheleleyo neemfuno ze-asphalt. indawo. Ukusasazwa kwe-asphalt kufuneka kuqinisekiswe ngokupheleleyo ngokwemizobo yokwakha ukuququzelela indawo esondeleyo yeziko lezityalo zokuxuba i-asphalt.

Inqaku lesibini kukuqonda kunye nokuqonda izinto ezisisiseko zokwakhiwa kwesikhululo sokuxuba, kubandakanywa amanzi, umbane kunye nendawo yomgangatho; inqaku lokugqibela limalunga nokusingqongileyo kwendawo yokwakha. Ekubeni isityalo sokuxuba i-asphalt sisiseko sokucubungula kunye neqondo eliphezulu lokwakhiwa komatshini, ungcoliseko olunjengothuli kunye nengxolo luya kuba lukhulu. Oku kufuna ukuba xa sikhetha isiza, kufuneka sizame ukuphepha iindawo zokuhlala, izikolo, iindawo zokufuya nezinye iindawo apho abantu nemfuyo baxinanisene khona, ukuze kuncitshiswe impembelelo yokusingqongileyo kangangoko kunokwenzeka.
