Okokuqala, sebenzisa u-28 wokulinganisa uphahla × ubukhulu obungu-35mm.

Lungisa ungqimba lokuqala lwethayela le-asphalt, bese inhlaka ibheke phezulu, bese uyilungisa ngqo ophahleni eduze kophahla oluphansi. Kolunye uhlangothi lwe-cornice empandeni yodonga, ungqimba lokuqala lwethayela le-asphalt lunwebeka kusuka ku-5 kuya ku-10 mm. Lungisa umhlabathi ngesipikili esingu-50.8 mm ukusuka phansi kwezinhlangothi zombili kanye no-25.4 mm ukusuka ohlangothini, bese ulubeka ngokulinganayo ohlangothini oluvundlile phakathi kwezipikili ezimbili. Beka izipikili ezimbili bese ubamba umugqa ovundlile.

Beka ungqimba lokuqala lwethayela le-asphalt, sula ungqimba lokuqala lwethayela le-asphalt elingu-167mm, bese ubeka lonke ithayela le-asphalt. Qondanisa isitini sokuqala se-asphalt ekugcineni kodonga kanye nonqenqema lwengqimba yokuqala yesitini se-asphalt eceleni kwe-cornice. Lungisa ngezipikili ku-60.8mm kusukela emaphethelweni womabili kuya phansi kanye no-35.4mm ohlangothini, bese ubeka ezinye izipikili ezimbili ohlangothini oluvundlile lwezipikili ezimbili bese usika umugqa ovundlile.

Beka ungqimba lwesibili lwethayela le-asphalt. Uhlangothi lwengqimba lokuqala lwezitini ezibheke i-asphalt lwengqimba yesibili lubekwe eceleni kwengxenye yeqabunga ohlangothini lwengqimba lokuqala lwezitini ezibheke i-asphalt. Ingaphansi lengqimba yesibili yethayela le-asphalt ligobile phezulu kwengxenye yokuhlobisa yengqimba yokuqala yethayela le-asphalt. Sebenzisa umugqa ovundlile oqoshiwe kungqimba lokuqala lwethayela le-asphalt ukuze wenze phansi kwengqimba yesibili yethayela le-asphalt lihambisane ne-cornice, bese ulungisa ungqimba lwesibili lwethayela le-asphalt ngezipikili.

Beka ungqimba lwesithathu lwethayela le-asphalt, usike lonke ibala lesendlalelo sokuqala sethayela le-asphalt lesendlalelo sesithathu sethayela le-asphalt, ulihlanganise nesendlalelo sokuqala sethayela le-asphalt lesendlalelo sesibili sethayela le-asphalt, wenze umkhawulo ongezansi wesendlalelo sesithathu sethayela le-asphalt uhlanzeke phezulu kwengxenye yokuhlobisa yesendlalelo sesibili sethayela le-asphalt, bese ulibeka bese ulilungisa ngokulandelana ngesendlalelo sesithathu sethayela le-asphalt.

Faka amathayili e-asphalt emgodini. Amathayili e-asphalt ophahla oluhlanganayo kufanele abekwe emgodini ngesikhathi esifanayo, noma uhlangothi ngalunye kufanele lwakhiwe ngokwehlukana, futhi kufanele abekwe ku-75mm ukusuka emugqeni ophakathi we-gutter. Bese ubeka ithayili le-asphalt le-gutter phezulu eceleni kolunye lwezingodo zophahla bese welula phezu komsele, ukuze ithayili lokugcina le-asphalt le-gutter lendlalelo lidlulele ophahleni oluseduze okungenani ama-300 mm, bese ubeka ithayili le-asphalt le-gutter eceleni kwezingodo zophahla eziseduze bese welula uye emgodini kanye nethayili le-asphalt le-drainage ditch elalibekwe ngaphambilini, elizolukwa ndawonye. Ithayili le-asphalt le-trench kufanele liqiniswe ngokuqinile emseleni, futhi ithayili le-asphalt le-trench kufanele liqiniswe ngokulungisa nokuvala umsele.

Uma ubeka amathayili e-asphalt e-ridge, qala ulungise kancane amathayili e-asphalt amaningana okugcina abekwe phezulu ezindaweni ezimbili eziphezulu zommango othambekele kanye nommango, ukuze amathayili e-asphalt e-ridge amboze ngokuphelele amathayili e-asphalt aphezulu, futhi ububanzi obuhambisanayo bemimango ezinhlangothini zombili zommango bufane. Ngemva kokuba isipikili sesilungisiwe, gcoba ithayili le-asphalt eliveziwe ngeglue ye-asphalt.
