Choyamba, gwiritsani ntchito 28 pa denga × 35mm makulidwe a simenti yofanana ndi matope.

Ikani thailo loyamba la matailo a phula, ndi guluu loyang'ana mmwamba, ndipo liyikeni molunjika padenga pansi pa denga. Kumapeto kwa cornice pa muzu wa khoma, thailo loyamba la matailo a phula limakula 5 mpaka 10 mm. Konzani pansi ndi msomali 50.8 mm kuchokera pansi pa malekezero onse awiri ndi 25.4 mm kuchokera m'mbali, kenako liyikeni mofanana mbali yopingasa pakati pa misomali iwiri. Ikani misomali iwiri ndikugwira mzere wopingasa.

Ikani thailo loyamba la phula, pukutani 167mm ya thailo loyamba la phula, kenako ikani thailo lonse la phula. Konzani njerwa yoyamba ya phula kumapeto kwa khoma ndi m'mphepete mwa thailo loyamba la njerwa ya phula pambali pa chimanga. Konzani ndi misomali pa 60.8mm kuchokera kumapeto onse mpaka pansi ndi 35.4mm kuchokera m'mbali, kenako ikani misomali ina iwiri mbali yopingasa ya misomali iwiriyo ndikudula mzere wopingasa.

Ikani gawo lachiwiri la matailosi a phula. Mbali ya gawo loyamba la njerwa yoyang'ana phula la gawo lachiwiri imazunguliridwa ndi theka la tsamba kuchokera kumbali ya gawo loyamba la njerwa yoyang'ana phula. Pansi pa gawo lachiwiri la matailosi a phula limapindika ndi pamwamba pa cholumikizira chokongoletsera cha gawo loyamba la matailosi a phula. Gwiritsani ntchito mzere wopingasa womwe wadulidwa pa gawo loyamba la matailosi a phula kuti pansi pa gawo lachiwiri la matailosi a phula lifanane ndi cornice, ndikukhazikitsa gawo lachiwiri la matailosi a phula ndi misomali.

Ikani gawo lachitatu la matailosi a phula, dulani tsamba lonse la gawo loyamba la matailosi a phula la gawo lachitatu la matailosi a phula, lizungulireni ndi gawo loyamba la matailosi a phula la gawo lachiwiri la matailosi a phula, pangani m'mphepete mwa gawo lachitatu la matailosi a phula kuti lizime pamwamba pa cholumikizira chokongoletsera cha gawo lachiwiri la matailosi a phula, kenako liyikeni ndikulikonza motsatizana ndi gawo lonse lachitatu la matailosi a phula.

Ikani matailosi a phula pa ngalande. Matailosi a phula a denga lolumikizana ayenera kuyikidwa pa ngalande nthawi yomweyo, kapena mbali iliyonse iyenera kupangidwa padera, ndipo iyenera kuyikidwa pa 75mm kuchokera pakati pa ngalande. Kenako ikani matailosi a phula la phula mmwamba pa denga limodzi ndikulitambasula pamwamba pa ngalande, kotero kuti matailosi omaliza a phula la phula la denga afikire padenga lapafupi kwa osachepera 300 mm, kenako ikani matailosi a phula la phula m'mbali mwa denga lapafupi ndikufikira pa ngalande ndi matailosi a phula la phula lomwe linali litayikidwa kale, lomwe liyenera kulumikizidwa pamodzi. Matailosi a phula la phula ayenera kukhazikika mwamphamvu mu ngalande, ndipo matailosi a phula la phula ayenera kukhazikika pokonza ndi kutseka ngalande.

Mukayika matailosi a asphalt a ridge, choyamba sinthani pang'ono matailosi angapo omaliza a asphalt omwe adayikidwa mmwamba pamwamba pa malo awiri apamwamba a ridge ndi ridge, kuti matailosi a asphalt a ridge aphimbe matailosi apamwamba a asphalt, ndipo m'lifupi mwa ridges mbali zonse ziwiri za ridge ndi chimodzimodzi. Pambuyo poti msomali wakhazikika, jambulani matailosi a asphalt omwe aonekera ndi guluu wa asphalt.
