Ndi chitukuko cha anthu komanso kukula kwachuma kwa dziko lathu, zomangamanga zapakhomo zikukula mofulumira komanso mofulumira. Mosafunikira kunena, kugwiritsa ntchito msika kwa zosakaniza zathu za asphalt kukuchulukiranso pang'onopang'ono. Ogwiritsa ntchito ambiri ndi opanga amawona kuthekera kwa msika pamsika uno. Zayikidwa kale. Choncho, pochita izi, kusankha malo omanga ndikofunika kwambiri. Malo a chomera chosakaniza phula amagwirizana mwachindunji ndi ntchito yake yayitali.

Nthawi zambiri, pali zinthu zitatu zofunika kusankha malo oyenera kumangapo phula losakaniza phula. Mbali yake ndi yoti wogwiritsa ntchito ayenera kudziwa mayendedwe a malo omanga. Popeza kuti mtunda wa mayendedwe a asphalt yaiwisi umakhudza mwachindunji ubwino wa asphalt, posankha phula la konkire, adiresi ya malo osakaniza ayenera kuganiziridwa mokwanira kuti akwaniritse zosowa za malowa mokwanira momwe angathere. Wopangayo akuyeneranso kutsimikizira kugawa kwa asphalt pogwiritsa ntchito zojambula zomangira kuti malo omwe ali pafupi ndi zida zosakaniza asphalt apezeke.
Mbali yachiwiri ndi yakuti opanga ayenera kudziwa bwino ndi kumvetsetsa zofunikira za zipangizo zosakaniza phula, monga madzi, magetsi ndi malo apansi omwe amafunikira panthawi yogwiritsira ntchito zida zosakaniza phula.
Mbali yomaliza yoti muiganizire ndi malo omangapo. Malo osakaniza a asphalt ndi malo opangira makina omwe ali ndi makina apamwamba kwambiri, kotero fumbi, phokoso ndi zonyansa zina zomwe zimapangidwira panthawi yokonza zidzakhala zovuta kwambiri. Choncho, posankha malo omanga, masukulu ndi magulu okhalamo ayenera kupeŵedwa momwe angathere. Chepetsani kukhudzidwa ndi chilengedwe.
