Ukukhetha imishini efanele yokuncibilikisa i-asphalt kudinga ukucatshangelwa kwezidingo zokukhiqiza.

Okokuqala, cabangela indlela yokushisa yemishini, njengokushisa kagesi, amafutha ashisayo noma umusi, njll., Ukuqinisekisa ukusatshalaliswa kokushisa okufanayo nokuphila isikhathi eside;
Okwesibili, kufanele kuqashelwe ukuthi amandla okuncibilika angakwazi yini ukuhlangabezana nezidingo zokukhiqiza okukhulu;
Okwesithathu, cabangela izinga lokuzenzakalela kanye nokuthi uhlelo lokulawula lungakwazi yini ukuthuthukisa ikhwalithi yomkhiqizo ngempumelelo;
Yiqiniso, kufanele kuqashelwe futhi ekwakhiweni kwesakhiwo somshini ukuvimbela ukuvuza kwezinto ezibonakalayo nokuqinisekisa ukusebenza okuphephile.
Kunconywa ukwenza ukukhetha okunengqondo ngokusekelwe esimweni sangempela sokukhiqiza lapho uthenga ukuze uhlangabezane nezidingo zakho zokukhiqiza kanye nekhwalithi.
