Izityalo zokuxuba i-asphalt yenye yezona zixhobo ezibalulekileyo zokuvelisa iimveliso ze-asphalt. Ukuba ayiphumeleli, imveliso yemveliso iya kuncipha ngokuqinisekileyo. Lo ngumthwalo onzima ofanelwe ukuqwalaselwa, ngoko ke zeziphi iingxaki ezihlala zenzeka kwizityalo zokuxuba i-asphalt?

Eyona nto ixhaphakileyo kukungazinzi kwemveliso kunye nokusebenza kakuhle kwezixhobo zokusebenza. Emva kokuhlalutya, kuyaziwa ukuba izizathu eziphambili zolu hlobo lokusilela zezi zilandelayo:
1. Umlinganiselo ongafanelekanga wemathiriyeli ekrwada;
2. Umgangatho ongekho mgangathweni wemathiriyeli ekrwada;
3. Ixabiso eliphantsi lokutshisa amafutha kwisixhobo;
4. Ukumiselwa okungafanelekanga kweeparamitha zokusebenza kwezixhobo.
Emva kokufumanisa isizathu sokuba unobangela, thatha izisombululo ezihambelanayo.
Ukongeza kwintsebenzo ephantsi, ukushisa kokukhutshwa kwesityalo sokuxuba i-asphalt ngamanye amaxesha akunakuzinza kwaye akukwazi ukuhlangabezana neemfuno eziqinileyo zokushisa. Isizathu sale ngxaki asichanekanga ulawulo lokushisa lokushisa, kwaye ubukhulu bomlilo ovuthayo bufuna ukulungiswa ukuze kuphuculwe le meko.
