Choyamba, gwiritsani ntchito 28 padenga la × 35mm wandiweyani wa simenti wosanjikiza.

Yambani wosanjikiza woyamba wa matailosi a asphalt, ndi zomatira zikuyang'ana m'mwamba, ndipo perekani mwachindunji padenga pamunsi pa denga lotsetsereka. Kumapeto kumodzi kwa cornice pa muzu wa khoma, wosanjikiza woyamba wa matailosi asphalt amafikira 5 mpaka 10 mm. Konzani pansi ndi msomali 50,8 mm kuchokera pansi pa malekezero onse ndi 25.4 mm kuchokera kumbali, ndiyeno muyike mofanana mu njira yopingasa pakati pa misomali iwiri. Ikani misomali iwiri ndikugwira mzere wopingasa.

Ikani matailosi a asphalt woyamba wosanjikiza, pukutani 167mm pagawo loyamba la phula, kenako ikani matailosi onse a asphalt. Gwirizanitsani njerwa yoyamba ya asphalt kumapeto kwa khoma ndi m'mphepete mwa mzere woyamba wa njerwa ya asphalt pambali pa cornice. Konzani ndi misomali pa 60.8mm kuchokera malekezero onse mpaka pansi ndi 35.4mm kuchokera kumbali, kenaka ikani misomali ina iwiri munjira yopingasa ya misomali iwiriyo ndikujambula mzere wopingasa.

Ikani gawo lachiwiri la matailosi a asphalt. Mbali ya gawo loyamba la njerwa yoyang'anizana ndi phula ya gawo lachiwiri imagwedezeka ndi theka la tsamba kuchokera kumbali yoyamba ya njerwa yoyang'ana phula. Pansi pa gawo lachiwiri la matailosi a asphalt ndi osungunuka ndi pamwamba pa cholumikizira chokongoletsera choyamba cha phula. Gwiritsani ntchito mzere wopingasa womwe umagwedezeka pagawo loyamba la phula la phula kuti pansi pa gawo lachiwiri la phula la phula likhale lofanana ndi cornice, ndikukonza gawo lachiwiri la matailosi a asphalt ndi misomali.

Ikani gawo lachitatu la matailosi a asphalt, kudula tsamba lonse la phula loyamba la phula lachitatu la matailosi a asphalt, gwedezani ndi gawo loyamba la phula la phula lachiwiri la matailosi a phula, pangani m'mphepete mwa phula lachitatu la phula la phula ndi pamwamba pa cholumikizira chachiwiri cha phula la phula, ndiyeno sungani bwino lachitatu ndi phula.

Yatsani matailosi a asphalt pa ngalande. Matailosi a asphalt a madenga ophatikizika adzayikidwa ku ngalande nthawi imodzi, kapena mbali iliyonse iyenera kumangidwa padera, ndipo iyenera kuyikidwa ku 75mm kuchokera pakati pa mzere wa ngalande. Kenako ikani matailosi a phula la phula m'mwamba m'mphepete mwa denga ndikuwonjezera pa ngalandeyo, kuti matailosi omaliza a asphalt osanjikiza apitirire mpaka denga loyandikana kwa osachepera 300 mm, ndiyeno ikani matailosi amtundu wa phula m'mphepete mwa denga ndikufikira ku ngalande ndi ngalande yomwe idayikidwapo kale idzakhala matailosi opangidwa ndi phula. Tile ya asphalt ya ngalande iyenera kukhazikika bwino mu ngalandeyo, ndipo matayala a asphalt a ngalande adzakhazikitsidwa mwa kukonza ndi kusindikiza ngalandeyo.

Mukayika matailosi a asphalt, choyamba sinthani pang'ono matailosi angapo omaliza omwe adayikidwa pamwamba pamiyala iwiri yamtunda ndi phirilo, kuti matailosi a phula atsekeretu matailosi apamwamba, ndipo m'lifupi mwake m'lifupi mwake mbali zonse za phirilo ndi chimodzimodzi. Msomali ukatha, valani matailosi a asphalt owonekera ndi guluu wa asphalt.
