Ithayela le-asphalt libizwa nangokuthi ithayela le-glass fiber, ithayela le-linoleum kanye nethayela le-asphalt le-glass fiber. Ithayela le-asphalt aliyona nje into entsha yokwakha engangeni manzi yobuchwepheshe obuphezulu, kodwa futhi liyinto entsha yophahla yokwakha engangeni manzi yophahla. Ukukhethwa nokusetshenziswa kwesidumbu kuhlobene kakhulu namandla, ukumelana namanzi, ukuqina, ukumelana nokuqhekeka, ukumelana nokuvuza kanye nezinto zesidumbu. Ngakho-ke, ikhwalithi yezinto ze-matrix ithinta ngqo ikhwalithi yesitini se-asphalt. Ikhwalithi kanye nokwakheka kwezithako, ukumelana nokushisa okuphezulu kanye nokumelana nokuguga kwe-ultraviolet kwethayela le-asphalt kubaluleke kakhulu. I-United States ingamelana nokushisa okuphezulu okungu-120 degrees Celsius, kuyilapho indinganiso yaseShayina ingu-85 degrees Celsius. Umsebenzi oyinhloko wethayela le-asphalt, ikakhulukazi izinto zokumboza ithayela le-asphalt elinombala, ukumboza okuvikelayo. Ukuze lingashiswa ngqo yimisebe ye-ultraviolet, futhi kukhiqizwe imibala ekhanyayo neguquguqukayo ebusweni bamathayela e-ceramic. Okokuqala, sebenzisa u-28 ophahleni× Ukulinganisa udaka lukasimende oluwugqinsi olungama-35mm.

Amathayela e-asphalt ophahla oluhlanganayo kufanele abekwe emgodini ngesikhathi esifanayo, noma uhlangothi ngalunye kufanele lwakhiwe ngokwehlukana, futhi kufanele abekwe ku-75mm ukusuka emgqeni ophakathi we-gutter. Bese ugoba ithayela le-asphalt le-gutter phezulu kwelinye lama-eve ophahleni bese welula phezu komsele, ukuze ithayela lokugcina le-asphalt le-gutter lesendlalelo lidlulele ophahleni oluseduze okungenani ama-300 mm, bese ugoba ithayela le-asphalt le-gutter eceleni kwama-eve ophahleni aseduze bese welula e-gutter kanye nethayela le-asphalt le-drainage ditch elalibekwe ngaphambilini, elizolukwa ndawonye. Ithayela le-asphalt le-trench kufanele liqiniswe ngokuqinile emseleni, futhi ithayela le-asphalt le-trench kufanele liqiniswe ngokulungisa nokuvala umsele. Lapho ubeka amathayela e-asphalt e-ridge, qala ulungise kancane amathayela okugcina amaningana e-asphalt abekwe phezulu ezindaweni ezimbili eziphezulu ze-ridge ethambekile kanye ne-ridge, ukuze amathayela e-asphalt e-ridge amboze ngokuphelele amathayela e-asphalt aphezulu, futhi ububanzi obuhambisanayo be-ridge kuzo zombili izinhlangothi ze-ridge bufane.
