ZOSEFA MAFUTA

Mapiritsi a asphalt omwe amatsatiridwa ndi zida zofunika kwambiri pantchito yomanga, makamaka pakuyala ndi kukonza phula pamisewu. Makinawa asintha momwe misewu imamangidwira, ndikupangitsa kuti misewuyo ikhale yabwino komanso yolondola yomwe imapangitsa kuti ikhale yabwino komanso yolimba.

M'ntchito yomanga misewu, kugwiritsa ntchito ma phula omwe amatsatiridwa ndi asphalt kwatchuka kwambiri chifukwa chotha kupereka njira zosalala komanso zosalala. M'nkhaniyi, tiwona mbali zosiyanasiyana za phula la asphalt, kuphatikizapo mawonekedwe awo, ubwino, ndi kufunikira kwawo pa ntchito yomanga.

Zopalasa phula zotsatiridwa ndi makina olemetsa okhala ndi mayendedwe okwawa kapena malamba omwe amawalola kuyenda movutikira m'malo ovuta komanso otsetsereka. Kuyenda uku, kuphatikizidwa ndi ma auger screeds awo osinthika, kumapangitsa kukhala kosunthika kwambiri komanso koyenera kugwiritsa ntchito mapulogalamu osiyanasiyana, kuyambira misewu yayikulu ndi ma driveway mpaka malo oimikapo magalimoto ndi mabwalo a ndege.

Kukhazikitsidwa kwa ma trached asphalt pavers kwasintha kwambiri njira zopangira, zomwe zimapangitsa kuti zikhale zogwira mtima komanso zolondola. Makinawa amapangidwa kuti azigwira ntchito zambiri zosakanikirana ndi phula, zomwe zimagawidwa mofanana pamsewu pogwiritsa ntchito malamba onyamula katundu, ma augers, ndi tamper bar. Kugwiritsa ntchito njira zapamwamba zotere kumapangitsa kuti pakhale kugawa kosalala komanso kofanana, kuteteza mavuto omwe angakhalepo monga tokhala, malo osagwirizana, ndi kulephera kwapamsewu msanga.

Opalasa phula omwe amatsatiridwa asintha ntchito yomanga misewu, ndikukhazikitsa miyezo yatsopano yogwirira ntchito bwino, zokolola, komanso mtundu. Kukwanitsa kwawo kupereka njira zoyendetsera bwino, ngakhale kugawa phula, komanso njira zotetezera chitetezo kwawapangitsa kukhala ofunikira kwambiri pantchito yamakono yomanga.

Pomaliza, kukhazikitsidwa kwa phula lotsata phula kwasintha momwe misewu imapangidwira. Mwa kuwongolera luso, kulondola, ndi chitetezo, makinawa akhala mbali yofunika kwambiri pa ntchito yomanga misewu. Ndi kuthekera kwawo popereka misewu yosalala komanso yolimba, ma phula omwe amatsatiridwa akupitilizabe kupititsa patsogolo chitukuko cha zomangamanga zodalirika komanso zokhazikika kwazaka zikubwerazi.
