Ming'alu ndi matenda omwe amapezeka m'misewu yayikulu komanso misewu ya asphalt. Ndalama zambiri zimagwiritsidwa ntchito pakupanga crack m’dziko chaka chilichonse. Pachifukwa ichi, ndikofunikira kwambiri kutenga njira zochiritsira zofananira ndi matenda enieni amsewu ndikuchepetsa mtengo wokonza.
Kwa ming'alu, nthawi zambiri palibe mankhwala omwe amafunikira. Ngati pali ming'alu yambiri pagawo lililonse, kusindikiza pamwamba kungathe kuchitidwa pa iwo; kwa ming'alu yaing'ono ndi ming'alu yaying'ono, popeza sizinawonongeke, nthawi zambiri chivundikiro chokhacho chimapangidwa pamwamba, kapena ming'aluyo imapangika ndikudzazidwa ndi zomatira kuti atseke ming'alu.

Kugwiritsa ntchito guluu caulking ndi imodzi mwa njira zotsika mtengo kwambiri zokonza misewu. Imatha kutseka bwino ming'alu, kuletsa kufalikira kwa ming'alu yamsewu chifukwa cha kulowa kwamadzi, ndikupewa kuyambitsa matenda oopsa, potero kumachepetsa kuwonongeka kwa ntchito zogwiritsa ntchito misewu, kuletsa kuchepa kwachangu kwa index ya misewu, ndikukulitsa moyo wautumiki. msewu.
Pali mitundu yambiri ya zomatira pamsika, ndipo zida ndi njira zaukadaulo zomwe zimagwiritsidwa ntchito ndizosiyana pang'ono. Guluu wa potting wopangidwa ndikupangidwa ndi Sinoroader ndi chinthu chosindikizira mumsewu ndikumangidwira kutentha. Amapangidwa ndi matrix asphalt, polymer molecular polymer, stabilizer, zowonjezera ndi zinthu zina kudzera pakukonza kwapadera. Izi zimamatira kwambiri, kusinthasintha kwa kutentha kochepa, kukhazikika kwamafuta, kukana madzi, kukana kuyika komanso kukana kukalamba.
