Okokuqala, sebenzisa i-28 kuphahla × 35mm ubukhulu besamente yokulinganisa umgangatho.

Gcoba umaleko wokuqala wethayile ye-asphalt, kunye ne-adhesive ejonge phezulu, kwaye uyibeke ngokuthe ngqo eluphahleni kunye nophahla olusezantsi lwethambeka. Kwesinye isiphelo se-cornice kwingcambu yodonga, uluhlu lokuqala lwe-asphalt tile lunweba kwi-5 ukuya kwi-10 mm. Lungisa umhlaba ngesikhonkwane 50.8 mm ukusuka ezantsi kweziphelo zombini kunye ne-25.4 mm ukusuka kwicala, uze uyibeke ngokulinganayo kwi-horizontal direction phakathi kwezikhonkwane ezimbini. Beka izikhonkwane ezi-2 kwaye ubambe umgca othe tye.

Beka uluhlu lokuqala lwe-asphalt tile, sula i-167mm yoluhlu lokuqala lwe-asphalt tile, uze ubeke yonke i-asphalt tile. Ukulungelelanisa isitena se-asphalt sokuqala ekupheleni kodonga kunye nomda womgangatho wokuqala wesitena se-asphalt ecaleni kwe-cornice. Lungisa ngezikhonkwane kwi-60.8mm ukusuka kwiziphelo zombini ukuya ezantsi kunye ne-35.4mm ukusuka kwicala, emva koko usete izikhonkwane ezimbini kwicala elithe tyaba lezo zikhonkwane ezimbini kwaye ucofe umgca oxwesileyo.

Beka uluhlu lwesibini lwethayile ye-asphalt. Icala lomaleko wokuqala we-asphalt ejongene nesitena somgangatho wesibini uphazamiseka ngesiqingatha segqabi ukusuka kwicala lomgangatho wokuqala wesitena esijongene ne-asphalt. I-bottom of the second layer of asphalt tile is flush with top of the decoration joint of the first layer of asphalt tile. Sebenzisa umgca onqamlekileyo otyunjwe kwinqanaba lokuqala le-asphalt tile ukwenza i-bottom of the second layer of asphalt tile parallel to cornice, kwaye ulungise uluhlu lwesibini lwe-asphalt tile ngezikhonkwane.

Beka umaleko wesithathu wethayile ye-asphalt, unqumle iblade yonke yomaleko wokuqala wethayile ye-asphalt yomaleko wesithathu wethayile ye-asphalt, uyigxadaze ngomaleko wokuqala wethayile ye-asphalt yomaleko wesibini wethayile ye-asphalt, yenza umda ongezantsi woluhlu lwesithathu lwethayile ye-asphalt ugungxule kunye nomphezulu wokudibanisa okuhombisayo komaleko wesibini wethayile ye-asphalt, kwaye emva koko uyibeke ngempumelelo kwaye uyilungise njengethayile lesithathu.

Gaba iithayile zeasphalt kwigatha. Iithayile ze-asphalt zophahla oludibanayo ziya kufakwa kwi-gutter ngexesha elinye, okanye icala ngalinye liya kwakhiwe ngokwahlukileyo, kwaye liya kubekwa kwi-75mm ukusuka kumgca ophakathi we-gutter. Emva koko gaca ithayile yeasphalt yomjelo ukuya phezulu ecaleni komnye wemivalo yophahla kwaye unwebe phezu komjelo, ukuze ithayile yokugqibela yeasphalt yomaleko idlulele kuphahla olukufuphi ubuncinane kangange-300 mm, kwaye emva koko ugalele ithayile ye-asphalt yomjelo ecaleni kophahla olucandekileyo kwaye unwebe ukuya kumjelo wokuhamba kwamanzi kunye nomsele wokuhambisa amanzi owenziwe ngaphambili oya kuba yithayile elukiweyo. I-tile ye-asphalt yomsele iya kulungiswa ngokuqinileyo kumsele, kwaye i-tile ye-asphalt yomsele iya kulungiswa ngokulungisa kunye nokutywinwa komsele.

Xa ubeka iithayile ze-asphalt ze-asphalt, okokuqala lungisa kancinane iithayile ezininzi zokugqibela ezibekwe phezulu kwimigangatho emibini ephezulu yomqolo othambekeleyo kunye nomqolo, ukuze iithayile ze-asphalt zomqolo zigubungele ngokupheleleyo iithayile ze-asphalt ezingaphezulu, kunye nobubanzi obuthe kratya beenduli kumacala omabini omqolo buyafana. Emva kokuba isikhonkwane silungisiwe, gcoba i-tile ye-asphalt evezwe nge-asphalt glue.
