Okokuqala, sebenzisa u-28 ukuze uphahleni × 35mm ukuqina kukasimende kokulinganisa.

Gcoba ungqimba lokuqala lwethayela le-asphalt, okunamathelayo kubheke phezulu, bese uphendla ngokuqondile ophahleni eduze kwemithambeka yophahla ngezansi. 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 sesitini esibheke i-asphalt songqimba lwesibili lunyakaziswa ngesigamu seqabunga ohlangothini lwesendlalelo sokuqala sesitini esibhekene ne-asphalt. 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 yonke i-blade yongqimba lokuqala lwethayela le-asphalt ungqimba lwesithathu lwethayela le-asphalt, lunyakazise ngongqimba lokuqala lwethayela le-asphalt lwesendlalelo sesibili sethayela le-asphalt, wenze unqenqema olungezansi lwethayela le-asphalt. ungqimba lwesithathu lwethayela le-asphalt ligudluze nengaphezulu lenhlanganisela yokuhlobisa yongqimba lwesibili lwethayela letiyela, bese ulala futhi ulilungise phansi ngokulandelana nalo lonke ungqimba lwesithathu lwethayela letiyela.

Gcoba amathayela e-asphalt ku-gutter. Amathayela etiyela ophahleni oluphambanayo ayobekwa kudoti ngesikhathi esifanayo, noma uhlangothi ngalunye luzokwakhiwa ngokuhlukana, futhi luzobekwa lube ngu-75mm ukusuka emgqeni ophakathi nendawo womzila. Bese upheca ithayela le-asphalt likadoti liye phezulu eduze kwelinye lama-eves ophahleni bese unweba phezu kukadoti, ukuze ithayela le-asphalt lokugcina likadoti lidlulele ophahleni oluseduze okungenani ama-300 mm, bese uvula ithayela le-asphalt likadoti eduze nendawo eseduze. ama-aves ophahleni futhi adlulele kuthayela kanye nethayela le-asphalt lokudonsa amanzi elalibekwe ngaphambilini, elizolukwa ndawonye. 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 etiyela amaningana abekwe phezulu ezindaweni ezimbili eziphezulu zommango othambekile kanye ne-ridge, ukuze amathayela e-asphalt e-ridge amboze ngokuphelele amathayela e-asphalt aphezulu, kanye nobubanzi obudlulanayo. amagquma ezinhlangothini zombili zommango ayafana. Ngemuva kokuthi isipikili sesilungisiwe, gcoba i-asphalt tile eveziwe nge-asphalt glue.
