Zida zamakina zamtundu uliwonse ziyenera kudutsa m'mapangidwe ake, kuyezetsa ndi njira zina zisanapangidwe, ndi momwemonso ndi malo osakaniza a asphalt. Malinga ndi kafukufukuyu, magawo otsatirawa ndi ofunikira pa chomera chilichonse chosakaniza phula.

Kwa chomera chonse chosakaniza phula, gawo lalikulu ndi dongosolo lake lolamulira, lomwe limaphatikizapo zida za hardware ndi mapulogalamu. Wolemba m'munsimu adzakutengerani mwatsatanetsatane ndondomeko yoyendetsera makina osakaniza a asphalt.

Pokonzekera zida zosinthidwa za phula, kuwongolera kutentha ndikofunikira kwambiri. Ngati kutentha kwa phula kuli kochepa kwambiri, phulalo limakhala lokhuthala, lopanda madzimadzi, komanso lovuta kulithira; ngati kutentha kwa phula kuli kwakukulu, kumbali imodzi, kumapangitsa kuti phula lizikalamba. Panthawi imodzimodziyo, kutentha kwa phula ndi kutuluka kwa phula la emulsified kudzakhala kokwera kwambiri, zomwe zidzakhudza kukhazikika kwa emulsifier ndi ubwino wa phula la emulsified. Zomwe aliyense ayenera kumvetsetsa ndikuti phula ndi gawo lofunika kwambiri la phula lopangidwa ndi emulsified, lomwe nthawi zambiri limawerengera 50% -65% ya phula lonse la phula.

Zida zoikamo thanki ya asphalt zikakhazikika, fufuzani ngati zolumikizirazo zili zolimba komanso zolimba, ngati mbali zoyenda zikuyenda bwino, ngati mapaipi ali osalala, komanso ngati mawaya amagetsi ali oyenera.

Popeza chomera chosakaniza phula chomwe chimagwiritsidwa ntchito chidagulidwa msanga, kuyatsa kwake ndi kuyanika kwake kumatha kukwaniritsa zofunikira pakuyatsa dizilo. Komabe, pamene mtengo wa dizilo ukuwonjezeka, mphamvu yachuma yogwiritsira ntchito zipangizozo imakhala yochepa komanso yochepa. Pachifukwa ichi, ogwiritsa ntchito akuyembekeza kuti zitha kuthetsedwa mwa kusintha njira yoyaka moto ya zomera zosakaniza phula. Kodi akatswiri ali ndi njira zotani zothanirana ndi zimenezi?
