Panthawi yomanga uinjiniya wapanjira, chifukwa cha zovuta zaukadaulo, pali mitundu yambiri yamavuto omwe angachitike. Pakati pawo, malo osakanikirana ndi asphalt ndiye zida zofunika kwambiri pantchitoyi, chifukwa chake ziyenera kulipidwa mokwanira. Tiyeni tiwone mavuto omwe mungakumane nawo.
Malinga ndi zomwe zinachitikira milandu yomanga m'dziko lathu kwa zaka zambiri, ntchito ya malo osakanikirana ndi asphalt idzakhudzidwa ndi zinthu zambiri. Pofuna kupititsa patsogolo ubwino wa ntchito za asphalt, tidzausanthula potengera zomwe zachitika pakupanga magalimoto amagetsi amtundu wamagetsi ndi zomangamanga, ndikupeza Zomwe zimayambitsa mavuto ena panthawi yomanga zimaperekedwa kuti zikupatseni zinachitikira zothandiza.
Mwachitsanzo, vuto lodziwika bwino pakumanga zida ndi vuto lotulutsa. Popeza vutoli lidzakhudza mwachindunji nthawi yomanga polojekitiyi ndi zina zambiri, pambuyo pofufuza, zinapezeka kuti pangakhale zifukwa zingapo za kutulutsa kosasunthika kapena kuchepa kwa malo osakanikirana a asphalt. Tsopano ndikugawana nanu.
1. Chiŵerengero cha zopangira ndi zosamveka. Zida zopangira ndi sitepe yoyamba pakupanga. Ngati chiŵerengero cha zipangizo zopangira ndi zosamveka, zidzakhudza ntchito yomangamanga yotsatira ndikuyambitsa mavuto monga kuchepa kwa khalidwe la zomangamanga. Chandamale kusakaniza chiŵerengero ndi kulamulira chiŵerengero cha zinthu ozizira kayendedwe ka mchenga ndi miyala, ndipo ziyenera kusinthidwa malinga ndi mmene zinthu zilili panthawi yopanga. Ngati mavuto okhudzana ndi kugwirizanitsa apezeka, kusintha koyenera kuyenera kuchitidwa kuti zitsimikizire kutuluka kwa malo osakaniza a asphalt.
2. Mtengo woyaka mafuta ndi wosakwanira. Pofuna kuonetsetsa kuti ntchito yomanga ikhale yabwino, mtundu wa mafuta oyatsa uyenera kusankhidwa ndikugwiritsidwa ntchito motsatira miyezo yodziwika. Kupanda kutero, ngati mwasankha kuwotcha dizilo, dizilo wolemera kapena mafuta olemera pamtengo wotsika, zingakhudze kwambiri kutentha kwa mbiya yowumitsa, zomwe zimapangitsa kuti pakhale phula losanganikirana la asphalt.
3. Kutentha kotulutsa kumakhala kosagwirizana. Monga tonse tikudziwira, kutentha kwa zinthu zotayira kudzakhudza kwambiri ubwino wa zinthuzo. Ngati kutentha kuli kokwera kwambiri kapena kutsika kwambiri, zipangizozi sizidzagwiritsidwa ntchito bwino ndipo zimakhala zowonongeka. Izi sizidzangowononga kwambiri mtengo wopangira phula losakaniza phula, komanso zimakhudza kupanga kwake.
