Yabelana:
1. Izinga lokushisa lokugandaywa kwetiyela livamise ukuba ngu-135~175℃. Ngaphambi kokuvula i-asphalt egandayiwe, kuyadingeka ukususa imfucumfucu esisekelweni somgwaqo ukuze uqinisekise ukuthi isisekelo somgwaqo somile futhi sihlanzekile. Ngasikhathi sinye, kuyadingeka ukuqinisekisa ubuhlakani bokuminyana kanye nokuqina kwe-base pavement, ebeka isisekelo esibalulekile sokugandaywa kwe-asphalt.

2. Izinga lokushisa lesixhumanisi sokucindezela kokuqala ngokuvamile liyi-110 ~ 140℃. Ngemuva kwengcindezi yokuqala, izisebenzi zezobuchwepheshe ezifanele kufanele zihlole ukuthi isicaba kanye nekhothamo lomgwaqo le-pavement, futhi balungise noma yiziphi izinkinga ngokushesha. Uma kukhona i-shift phenomenon phakathi nenqubo yokugingqika komgwaqo, ungalinda kuze kube yilapho izinga lokushisa lehla ngaphambi kokugingqika. Uma kuvela imifantu ephambanayo, hlola imbangela futhi uthathe izinyathelo zokuyilungisa ngesikhathi.
3. Izinga lokushisa lesixhumanisi sokucindezela kabusha ngokuvamile lingu-120~130℃. Inani lama-rollings kufanele libe ngaphezu kwezikhathi ezi-6. Kungale ndlela kuphela lapho ukuzinza nokuqina kwe-pavement kungaqinisekiswa.
4. Izinga lokushisa ekupheleni kokucindezela kokugcina kufanele libe likhulu kuno-90℃. Ukucindezela kokugcina kuyisinyathelo sokugcina sokuqeda izimpawu zamasondo, amaphutha nokuqinisekisa ukuthi ungqimba olungaphezulu lunokucaba okuhle. Njengoba ukuhlanganiswa kokugcina kudinga ukuqeda ukungalingani okusele kusukela kungqimba olungaphezulu ngesikhathi senqubo yokuhlanganisa kabusha futhi kuqinisekiswe ukugcwala kwendawo yomgwaqo, ingxube ye-asphalt nayo idinga ukuqeda ukuhlanganisa ekushiseni okulinganiselwe kodwa hhayi okuphezulu kakhulu.
