Abantu bakhetha itiyela ukukhanda umgwaqo? Isiteshi sokuxuba itiyela sithe kungenxa yalezi zizathu ezilandelayo:
Okokuqala, i-asphalt ine-flatness enhle, ukushayela kuyashelela futhi kukhululekile, umsindo ophansi, futhi akulula ukushelela emgwaqeni;

Okwesibili, itiyela linozinzo oluhle;
Okwesithathu, i-asphalt iyakha ngokushesha futhi kulula ukuyinakekela;
Okwesine, umgwaqo wetiyela ugeleza ngokushesha;
Okwesihlanu, imigwaqo egandayiwe ngetiyela ayiphazamisi abantu nezinye izinzuzo eziningi. I-Cement iyindawo eqinile, okumele ibe namalunga, futhi ukwakhiwa kunzima kakhulu. Ukunwetshwa kwe-thermal kanye nokufinyela ezinkathini ezine zonyaka nakho kujwayele ukuqhekeka.
Yiqiniso, itiyela nalo linemibi. Izinto ze-asphalt zimunca ukushisa. Lapho ilanga linamandla kakhulu ehlobo, i-asphalt izoncibilika kancane, okuholela ku-asphalt engakwazi ukugezwa ngamathayi emoto ehambayo. Impela likhanda ikhanda kumshayeli. Ngakho sivame ukuzwa ukuhlukunyezwa komshayeli.
