Zomera zosakaniza phula zimatulutsa fumbi lambiri komanso mpweya woipa wotayira panthawi yomanga. Pofuna kuchepetsa kuvulazidwa ndi zoipitsa izi, zida zoyenera zochotsera fumbi nthawi zambiri zimakonzedwa kuti zichiritsidwe. Pakalipano, mitundu iwiri ya zipangizo zochotsera fumbi, zomwe zimakhala ndi osonkhanitsa fumbi la mphepo yamkuntho ndi osonkhanitsa fumbi la thumba, nthawi zambiri amagwiritsidwa ntchito kusonkhanitsa zowononga momwe angathere kuti achepetse kuipitsidwa ndi kukwaniritsa miyezo ya malamulo oteteza chilengedwe.
Komabe, pochita izi, zida zosankhidwa zochotsa fumbi ziyenera kukwaniritsa zofunikira zina. Makamaka posankha zida zosefera, chifukwa pakapita nthawi yogwiritsira ntchito zida zosakaniza za asphalt ndi otolera fumbi la makina, zida zosefera zidzawonongeka chifukwa chazifukwa zina ndipo ziyenera kukonzedwa kapena kusinthidwa. Chifukwa chake, zomwe zosefera zomwe mungasankhe ndi funso loyenera kuliganizira. Njira yanthawi zonse ndikusankha molingana ndi zomwe zili ndi zofunikira za buku la malangizo a zida kapena buku lokonzekera, komabe sizoyenera.

Nthawi zambiri, pali mitundu yambiri yazinthu zopangira zosefera kuti zikwaniritse zofunikira zosiyanasiyana. Zopangira zosiyanasiyana zimakhala ndi mawonekedwe osiyanasiyana, ndipo mawonekedwe ogwiritsira ntchito kapena malo ogwirira ntchito omwe ali oyenera ndi osiyana. Choncho, mfundo yosankha zipangizo zosefera za zomera zosakaniza za asphalt ndi osonkhanitsa fumbi la thumba ndi: choyamba, kumvetsetsa bwino thupi ndi mankhwala a mpweya wokhala ndi fumbi wotulutsidwa panthawi yopanga, ndiyeno fufuzani mosamala luso la ulusi wosiyanasiyana musanapange. kusankha. Posankha zosefera, zinthu zomwe ziyenera kuganiziridwa ndi izi: mawonekedwe akuthupi ndi mankhwala a mpweya wokhala ndi fumbi, kuphatikiza kutentha, chinyezi, kuwononga, kuyaka ndi kuphulika.
Zomwe zimakhala ndi mpweya wokhala ndi fumbi pansi pazikhalidwe zosiyanasiyana ndizosiyana, ndipo zidzakhudzidwa ndi zinthu zambiri. Mpweya wa nsapato za mvula ulinso ndi zinthu zowononga. Poyerekeza, ulusi wa polytetrafluoroethylene, wotchedwa mfumu ya mapulasitiki, uli ndi katundu wabwino kwambiri, koma ndi wokwera mtengo. Choncho, posankha zipangizo zosefera za zomera zosakaniza za asphalt ndi osonkhanitsa fumbi la thumba, m'pofunika kumvetsetsa zinthu zazikulu zomwe zimachokera ku mankhwala a mpweya wokhala ndi fumbi ndikusankha zipangizo zoyenera.
Kuphatikiza apo, zida zosefera zosakaniza za asphalt ndi osonkhanitsa fumbi la thumba ziyenera kusankhidwa molingana ndi kukula kwa fumbi. Izi zimafuna kuyang'ana pa kusanthula kwakuthupi kwa fumbi, zinthu, kapangidwe kake ndi pambuyo pokonza zosefera, ndipo kusankha kuyenera kuphatikizidwa ndi zinthu monga mawonekedwe ndi kukula kwa tinthu tating'onoting'ono.
