Zomera za asphalt zamphamvu zimapangidwira kupanga miyala ya mastic asphalt ndipo tili ndi gawo mu pulogalamu yathu ya pulogalamu. Komanso timapanga ma cellulose dosing unit.Ndi antchito athu odziwa zambiri, sitimangopereka malonda a zomera zokha, komanso pambuyo pogulitsa chithandizo cha ntchito ndi maphunziro a ogwira ntchito.

SMA ndi yocheperako (12.5-40 mm) yokhala ndi mipata, yophatikizika kwambiri, HMA yomwe imagwiritsidwa ntchito ngati njira yapamtunda pamamangidwe atsopano ndi kukonzanso pamwamba. Ndi chisakanizo cha simenti ya asphalt, coarse aggregate, mchenga wophwanyidwa, ndi zowonjezera. Zosakaniza izi ndizosiyana ndi zosakanikirana zamtundu wa HMA zamtundu wamba chifukwa pali kuchuluka kokulirapo kwa kuphatikiza kwa SMA. Itha kugwiritsidwa ntchito m'misewu yayikulu yokhala ndi kuchuluka kwa magalimoto ambiri. Izi zimathandizira kuvala kosagwira ntchito komanso kukana kuphulika kwa matayala opindika. Pulogalamuyi imaperekanso kukalamba pang'onopang'ono komanso magwiridwe antchito abwino otsika.

SMA imagwiritsidwa ntchito kukulitsa kuyanjana ndi kulumikizana pakati pa magawo ophatikizika a HMA. Simenti ya asphalt ndi magawo ophatikizika bwino kwambiri amapereka utomoni womwe umapangitsa mwalawo kuyandikira. Mapangidwe osakaniza osakanikirana nthawi zambiri amakhala ndi simenti ya 6.0-7.0% ya simenti yapakati (kapena polymer-modified AC), 8-13% filler, 70% aggregate osachepera wamkulu kuposa 2 mm (No 10) sieve, ndi 0.3-1.5% ulusi kulemera kwa mix. Ulusi nthawi zambiri amagwiritsidwa ntchito kukhazikika kwa mastic ndipo izi zimachepetsa kukhetsa kwa binder pakusakaniza. Voids nthawi zambiri amasungidwa pakati pa 3% ndi 4%. Kukula kwakukulu kwa tinthu kumayambira 5 mpaka 20 mm (0.2 mpaka 0.8 in.).

Kusakaniza, mayendedwe, ndi kuyika kwa SMA kumagwiritsa ntchito zida zachikhalidwe ndi machitidwe osiyanasiyana. Mwachitsanzo, kutentha kwakukulu kosakanikirana kwa pafupifupi 175 ° C (347 ° F) nthawi zambiri kumakhala kofunikira chifukwa cha kuphatikizika kokulirapo, zowonjezera, komanso phula lowoneka bwino muzosakaniza za SMA. Komanso, pamene ulusi wa cellulose ukugwiritsidwa ntchito, nthawi yosakaniza iyenera kuwonjezeredwa kuti alole kusakaniza koyenera. Kugudubuza kumayamba nthawi yomweyo mutangoyika kuti mukwaniritse kachulukidwe msanga kutentha kusanachedwe kutsika kwambiri. Kuphatikizika kumachitika pogwiritsa ntchito ma 9-11 tonne (matani 10-12) oyenda ndi zitsulo. Kugwedezeka kungagwiritsidwenso ntchito mosamala. Poyerekeza ndi HMA wamba yowundana, SMA imakhala ndi kukana kukameta ubweya wabwino, kukana abrasion, kukana kusweka, komanso kukana kwa skid, ndipo ndiyofanana ndi kupanga phokoso. Table 10.7 ikuyimira kufananiza kwa gradation ya SMA yomwe imagwiritsidwa ntchito ku United States ndi Europe.
