Ndi chitukuko cha anthu komanso kusintha kwa moyo wa anthu, anthu amaika chidwi kwambiri pa ntchito yomanga mizinda. Kupanga ndi kupanga misewu ndiye chinsinsi chomanga mizinda. Chifukwa chake, kugwiritsa ntchito phula kukuwonjezeka, ndipo kuchuluka kwa zosakaniza za asphalt kukukula mwachilengedwe.

Zomera zosakaniza phula zimakumana ndi zolakwika zina mochulukirapo kapena mochepera pakugwiritsa ntchito. Zodziwika kwambiri ndizovala zosagwirizana za ma rollers othandizira ndi ma wheel rails. Nthawi zina padzakhala phokoso losazolowereka ndi kudziluma. Chifukwa chachikulu cha izi ndikuti chomera chosakaniza cha asphalt chakhala chikugwira ntchito kwa nthawi yayitali, ng'oma yowumitsa yamkati idzakhala ndi kutentha kwakukulu, ndiyeno kukangana kudzachitika pakati pa odzigudubuza ndi magudumu.
Zomwe zili pamwambazi zidzatsagananso ndi kugwedezeka kwakukulu, chifukwa chomera chosakaniza phula chidzapangitsa kuti kusiyana pakati pa njanji ya gudumu ndi chogudubuza chothandizira kusinthidwa molakwika pansi pa ntchito yowumitsa, kapena malo achibale a awiriwo adzakhala. zokhota. Mukakumana ndi izi, wogwiritsa ntchito ayenera kuwonjezera mafuta pamalo olumikizirana ndi chogudubuza chothandizira ndi njanji yama gudumu pambuyo pogwira ntchito tsiku lililonse.
Kuonjezera apo, ogwira nawo ntchito amafunikanso kumvetsera ndikusintha panthawi yake kulimba kwa mtedza wokonza pamene akuwonjezera mafuta, ndikusintha bwino mtunda pakati pa gudumu lothandizira ndi njanji yamagetsi. Izi zidzalola chomera chosakaniza phula kuti chizigwira ntchito bwino, malo onse okhudzana nawo akhoza kutsindika mofanana, ndipo sipadzakhala kugwedezeka.
