Okokuqala, sebenzisa u-28 ukuze uphahla × 35mm ukukala udaka lukasimende obukhulu.

Gcoba ungqimba lokuqala lwethayela le-asphalt, okunamathelayo kubheke phezulu, bese uphendla ngokuqondile ophahleni eduze komthambeka ophahleni phansi. Ngakolunye uhlangothi lwe-cornice empandeni yodonga, ungqimba lokuqala lwe-asphalt tile lunwebeka ku-5 kuya ku-10 mm. Lungisa umhlabathi nge-nail 50.8 mm kusukela phansi kokubili kokuphela kanye no-25.4 mm ukusuka ohlangothini, bese uyibeka ngokulinganayo endaweni evundlile phakathi kwezipikili ezimbili. Beka izipikili ezi-2 bese ubamba umugqa ovundlile.

Beka ungqimba lokuqala lwethayela le-asphalt, sula u-167mm wengqimba yokuqala yethayela le-asphalt, bese ubeka yonke i-asphalt tile. Qondanisa isitini se-asphalt sokuqala ekugcineni kodonga kanye nonqenqema longqimba lokuqala lwesitini se-asphalt eduze kwe-cornice. Lungisa ngezinzipho ku-60.8mm ukusuka emaphethelweni womabili uye phansi kanye no-35.4mm ukusuka ohlangothini, bese usetha ezinye izipikili ezimbili ngendlela evundlile yezinzipho ezimbili bese uhlwitha umugqa ovundlile.

Beka ungqimba lwesibili lwethayela le-asphalt. Uhlangothi lwesendlalelo sokuqala setiyela esibheke isitini songqimba lwesibili lunyakaziswa ngesigamu seqabunga ohlangothini lwesendlalelo sokuqala sesitini esibheke itiyela. Iphansi lesendlalelo sesibili sethayela letiyela lishaywa phezulu nengxenye yokuhlobisa yongqimba lokuqala lwethayela letiyela. Sebenzisa umugqa ovundlile ohlwithwe kungqimba lokuqala lwethayela le-asphalt ukuze wenze phansi kwesendlalelo sesibili sethayela le-asphalt lihambisane ne-cornice, futhi ulungise ungqimba lwesibili lwe-asphalt tile ngezipikili.

Beka ungqimba lwesithathu lwethayela le-asphalt, usike lonke icwecwe longqimba lokuqala lwethayela letiyela longqimba lwesithathu lwethayela letiyela, ulinyakazise ngongqimba lokuqala lwethayela letiyela lesendlalelo sesibili sethayela letiyela, wenze unqenqema olungezansi lwesendlalelo sesithathu sethayela letiyela lunyakaze phezulu kwenhlanganisela yokuhlobisa ungqimba lwesibili lwethayela letiyela, bese ubeka phansi lonke ungqimba lwe-asphalt ngempumelelo bese ululungisa ngempumelelo ungqimba lwe-asphalt.

Gcoba amathayela e-asphalt ku-gutter. Amathayela etiyela ophahleni oluphambanayo azobekwa kugutter ngesikhathi esifanayo, noma uhlangothi ngalunye luzokwakhiwa ngokuhlukana, futhi luzobekwa lube ngu-75mm ukusuka emugqeni ophakathi nendawo. Bese upheca ithayela le-asphalt likadoti liye phezulu eduze kwelinye lama-eves ophahleni bese unweba phezu kogutha, ukuze ithayela lokugcina letiyela likadoti lesendlalelo lidlulele ophahleni oluseduze okungenani ama-300 mm, bese upheca ithayela le-asphalt lodoti eduze kwama-aves ophahleni oluseduze futhi unabele kuthayela kanye nomsele wokudonsa amanzi owake wabekwa ngaphambili uzoba uthayela olulukiweyo. Ithayela le-asphalt lomsele kufanele liqiniswe ngokuqinile emseleni, futhi ithayela le-asphalt lomsele lizolungiswa ngokulungisa nokuvala umsele.

Lapho ubeka amathayela e-asphalt e-ridge, qala ngokulungisa kancane amathayela e-asphalt okugcina abekwe phezulu ezindaweni ezimbili eziphezulu ze-ridge ethambekele kanye ne-ridge, ukuze amathayela we-asphalt we-ridge amboze ngokuphelele amathayela e-asphalt aphezulu, nobubanzi obudlulele bezintambo ezinhlangothini zombili zommango buyafana. Ngemuva kokuthi isipikili sesilungisiwe, gcoba i-asphalt tile eveziwe nge-asphalt glue.
