Imifantu yizifo ezivamile zemigwaqo emikhulu kanye nemigwaqo yetiyela. Isamba esikhulu sezimali sisetshenziswa ekukhiqizweni kwe-crack ezweni minyaka yonke. Kulokhu, kubaluleke kakhulu ukuthatha izinyathelo zokwelashwa ezihambisanayo ngokuya ngezifo zomgwaqo zangempela futhi wehlise nezindleko zokuyilungisa.
Ukuze uthole imifantu, ngokuvamile akukho ukwelashwa okudingekayo. Uma kunemifantu eminingi endaweni ngayinye, ukuvala uphawu kungenziwa kuzo; ngenxa yemifantu emincane nemifantu emincane, njengoba bengakabonakali umonakalo wesakhiwo, ngokuvamile kuvame ukuvala kuphela isembozo sokuvala phezulu, noma imifantu i-caulked futhi igcwaliswe nge-caulking glue ukuze kuvalwe imifantu.

Ukusetshenziswa kwe-caulking glue kungenye yezindlela zokonga kakhulu zokugcinwa komgwaqo. Ingakwazi ukuvala imifantu ngokuphumelelayo, ivimbele ukwanda kwemifantu ngenxa yokungena kwamanzi, futhi igweme ukubangela izifo ezimbi kakhulu, ngaleyo ndlela ibambezele ukuwohloka kwemisebenzi yokusetshenziswa komgwaqo, ivimbele ukwehla ngokushesha kwenkomba yesimo somgwaqo, futhi yandise isikhathi sokusebenza komgwaqo. umgwaqo.
Kunezinhlobo eziningi ze-glue yokubumba emakethe, futhi izinto zokwakha nezindlela zobuchwepheshe ezisetshenziswayo zihluke kancane. Ingcina ye-potting eyakhiwe futhi yakhiqizwa yi-Sinoroader iyinto yokuvala umgwaqo ngokwakhiwa kokufudumeza. Yenziwe nge-matrix asphalt, i-polymer yamangqamuzana aphezulu, i-stabilizer, izithasiselo nezinye izinto ngokucubungula okukhethekile. Lo mkhiqizo unokunamathela okuhle kakhulu, ukuguquguquka okuphansi kwezinga lokushisa, ukuzinza kokushisa, ukumelana namanzi, ukumelana nokushumeka kanye nokumelana nokuguga.
