Isityalo sokuxuba i-asphalt sesinye sezixhobo ezibalulekileyo zokuvelisa iimveliso ze-asphalt. Ukuba ayiphumelelanga, umphumo wemveliso uya kuncitshiswa ngokuqinisekileyo. Lo ngumthwalo omele uqwalaselwe, ngoko zeziphi iingxaki ezihlala zisenzeka kwizityalo zokuxuba i-asphalt?
Ezona ziqhelekileyo ziyimveliso engazinzanga kunye nokusebenza okuphantsi kwemveliso yezixhobo. Emva kohlalutyo, siyazi ukuba ezona zizathu ziphambili zokungaphumeleli zezi zilandelayo:

1. Umlinganiselo ongafanelekanga womxube wezinto eziluhlaza;
2. Umgangatho wemathiriyeli ekrwada awukho kumgangatho;
3. Ixabiso lokutsha kwamafutha kwisixhobo liphantsi;
4. Iiparamitha zokusebenza kwezixhobo zisetwe ngokungafanelekanga.
Wakuba ufumanise unobangela, unokuthabatha amanyathelo angqinelanayo.
Ukongeza ekusebenzeni okuphantsi, ukushisa kokukhutshwa kwezityalo zokuxuba i-asphalt ngamanye amaxesha akuzinzi kwaye akukwazi ukuhlangabezana neemfuno ezingqongqo zokushisa. Isizathu sale ngxaki asichanekanga ulawulo lobushushu bokufudumala, kwaye ubukhulu bomlilo ovuthayo kufuneka bulungiswe ukuze kuphuculwe le meko.
