Ngophuhliso loluntu kunye nokuphuculwa kwemigangatho yokuphila kwabantu, abantu banikela ingqalelo ngakumbi nangakumbi kulwakhiwo lwasezidolophini. Uphuhliso nolwakhiwo lweendlela ngundoqo kulwakhiwo lwasezidolophini. Ngoko ke, ukusetyenziswa kwe-asphalt kuyanda, kwaye izinga lokusetyenziswa kwezityalo zokuxuba i-asphalt ngokwemvelo likhula ngokukhawuleza.

Izityalo zokuxuba i-asphalt ziya kudibana nezinye iimpazamo ngaphezulu okanye ngaphantsi ngexesha lokusetyenziswa. Eyona nto ixhaphakileyo kukunxiba okungalinganiyo kweerola ezixhasayo kunye neereyili zamavili. Ngamanye amaxesha kuya kubakho ingxolo engaqhelekanga kunye nokukrazula. Isizathu esona sizathu salokhu kukuba emva kokuba isityalo sokuxuba i-asphalt sisebenze ixesha elithile, idramu yokumisa yangaphakathi iya kuxhomekeka kwiqondo lokushisa eliphezulu, kwaye ke ukungqubuzana kuya kwenzeka phakathi kwee-roller ezixhasayo kunye neentsimbi zamavili.
Le meko ingentla nayo iya kukhatshwa kukungcangcazela kakhulu, kuba isityalo sokuxuba i-asphalt siya kubangela ngokuthe ngqo umsantsa phakathi komzila wevili kunye ne-roller exhasayo ukuba ilungelelaniswe ngokungafanelekanga phantsi kwesenzo sezinto zokomisa, okanye indawo ehambelanayo yababini iya kuba. igwetyiwe. Xa udibana nale meko, umsebenzisi kufuneka afake igrisi kwindawo yokunxibelelana nomphezulu werola exhasayo kunye nesondo likaloliwe emva kokusebenza kwemihla ngemihla.
Ukongezelela, abasebenzi nabo kufuneka banikele ingqalelo kunye nokulungelelanisa kwangexesha ukuqina kwe-nut yokulungisa ngelixa besongeza igrisi, kwaye balungelelanise ngokufanelekileyo umgama phakathi kwevili elixhasayo kunye ne-calibration wheel rail. Oku kuya kuvumela isityalo sokuxuba i-asphalt ukuba sisebenze kakuhle, zonke iindawo zoqhagamshelwano zinokugxininiswa ngokulinganayo, kwaye akuyi kubakho kunyikima.
