1. Chovala cha Primer-Prime Coat-Aggregate-Top (chomwe chimagwiritsidwa ntchito kwambiri m'njira zamagalimoto)
2. Choyambira chimagwiritsidwa ntchito popala (penti aggregate) ndi zolembedwa (zambiri zomwe zimagwiritsidwa ntchito panjira za njinga)
3. Utoto woyambira pamwamba (zopaka zokopa) -zolemba (zambiri zomwe zimagwiritsidwa ntchito m'njira zanjinga zanjinga) njira yopangira miyala
Dongosolo lopanda kutsetsereka la utoto limapangidwa ndi zomatira zapadera za polyurethane ndi mitundu yotentha kwambiri ya ceramic aggregates. Njira yosasunthika yamtundu ndi njira yatsopano yokongoletsera yokongoletsera yomwe imalola konkire yakuda yakuda ya asphalt ndi imvi ya konkire ya simenti kuti ifike pamtunda kupyolera mukupanga mitundu Mtunduwu ndi wokondweretsa diso ndipo umakhala ndi zotsatira zosasunthika.
Panjira yamtundu wosatsetsereka ndi yoyenera komanso njira yomanga yachangu, yolimba, yosasunthika, komanso mtundu wake ndi wogwirizana.
Ndi chitukuko cha kuchuluka kwa magalimoto m'mizinda, chitukuko ndi kugwiritsa ntchito zokutira zomangira zamitundu zosasunthika zakhala zikuchulukirachulukira. Mphepete mwamitundu siingokhala ndi ntchito yokongoletsera, komanso imakhala ndi ntchito yochenjeza. Pavement yopanda utoto ndi njira yofunika kwambiri yogwirira ntchito. Njira yotereyi imakutidwa ndi zokutira zamitundu zotsutsana ndi kutsetsereka kuti zipangitse kuti njirayo ikhale yogwira ntchito yoletsa kuterera.
Utoto wamafuta utha kugwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana,Utomoni wamafuta monga utoto, mphira, ndi zina zambiri. Chifukwa chiyani utomoni wamafuta ndi wodziwika kwambiri?
Pali njira ziwiri zazikulu zosinthira. Imodzi ndi hydrogenation modification, Petroleum Resin yomwe imawonjezera mgwirizano wapawiri mu molekyulu ya petroleum resin, Petroleum Resin potero imapangitsa kuti mtundu wake ukhale wolimba komanso kukhazikika kwa anti-oxidation. Mafuta a petroleum okhala ndi katundu wapadera amatha kukonzedwa powonjezera magulu a polar kapena zosintha monga monoolefin ku zipangizo.
