Inkqubo yokwakha ithayile ye-asphalt:

Ukulungiswa nokubekwa kwesakhiwo → ukupeyinta nokubethelela iithayile ze-asphalt → ukuhlolwa nokwamkelwa → uvavanyo lokunkcenkceshela.

Inkqubo yokwakha ithayile ye-asphalt:

(1) Iimfuneko zendlela esisiseko yokubeka iithayile ze-asphalt: indlela esisiseko yethayile ye-asphalt mayibe tyaba ukuqinisekisa ukuba uphahla luthe tyaba emva kokwakhiwa kwe-asphalt.

(2) Indlela yokulungisa ithayile ye-asphalt: ukuze kuthintelwe umoya omkhulu ekuphakamiseni ithayile ye-asphalt, ithayile ye-asphalt kufuneka ibe kufutshane nesiseko ukuze umphezulu wethayile ube tyaba. Ithayile ye-asphalt ibekwe kwisiseko sekhonkrithi kwaye iqiniswe ngezikhonkwane zentsimbi zethayile ye-asphalt ekhethekileyo (ngokuyintloko izikhonkwane zentsimbi, ezongezelelwe yiglu ye-asphalt).

(3) Indlela yokugalela ithayile ye-asphalt: ithayile ye-asphalt mayigalelwe phezulu ukusuka kwi-cornice (umqadi). Ukuze kuthintelwe ukuguguleka kwethayile okanye ukuvuza okubangelwa kukunyuka kwamanzi, isikhonkwane masigalelwe ngokwendlela yokugalela umaleko ngomaleko.

(4) Indlela yokubeka ithayile yangasemva: xa ubeka ithayile yangasemva, sika umngxuma wethayile yeasphalt, wahlule ube ziziqwenga ezine njengethayile yangasemva, uze uyilungise ngezikhonkwane ezimbini zentsimbi. Uze ugqume i-1/3 yendibaniselwano yeethayile ezimbini zeasphalt zeglasi. Umphezulu wegland wethayile yangasemva kunye nethayile yangasemva akufuneki ube ngaphantsi kwe-1/2 yendawo yethayile yangasemva.

(5) Inkqubela phambili yokwakha kunye namanyathelo okuqinisekisa
