Malo osakaniza phula amabweretsa mwayi kwa anthu. Chifukwa chiyani ndikunena choncho? Chifukwa aliyense ayenera kudziwa kuti ngati mukufuna kugwiritsa ntchito phula, muyenera kuligwiritsa ntchito potentha, chifukwa silingagwire ntchito ngati kuli kozizira, ndipo silingagwiritsidwe ntchito ngati lili lovuta, choncho liyenera kutenthedwa ndikugwedezeka. chepetsani zovuta mukamagwiritsa ntchito.

Tiyeni tikambirane za siteshoni phula kusakaniza kaye. Pokhapokha pomvetsa izi m'modzi ndi m'modzi tingathe kumvetsetsa bwino malo osakaniza a asphalt omwe tikambirana lero. Asphalt ndi madzi obiriwira obiriwira owoneka bwino omwe amapangidwa ndi ma hydrocarbons ndi zinthu zopanda zitsulo zolemera mosiyanasiyana. Pamwamba pake ndi wakuda ndipo amasungunuka mu carbon disulfide. Pa nthawi yomweyo, ndi madzi, chinyezi-umboni ndi odana ndi dzimbiri organic gelling zinthu. Itha kugawidwa makamaka m'mitundu itatu: phula la malasha, phula lamafuta ndi phula lachilengedwe. Phula limagwiritsidwa ntchito makamaka m'mafakitale monga zokutira, mapulasitiki, mphira, ndi misewu yokonza.
Misewu yathu imapangidwa ndi phula, yomwe imatha kutchedwanso phula, choncho nthawi zonse timati misewu ya asphalt. Kutentha kwa asphalt kumakhala kokwera kwambiri mukathira misewu, chifukwa pakutentha kotsika, kumakhala kolimba kuposa mwala ndipo sikungagwiritsidwe ntchito konse, chifukwa chake malo osakanikirana a asphalt amafunikira. Zida zophatikizira phula makamaka zimakhala ndi batching system, drying system, combustion system, kuyeza ndi kusanganikirana, phula, njira yoperekera ufa, silo yomalizidwa ndi dongosolo lowongolera. Malo osakaniza phula ndi malo ofunikira kwambiri popanga misewu. Malo osakaniza phula ndi zida zonse zopangira konkire ya phula, ndipo zida izi zimagwiritsidwa ntchito pothira misewu yayikulu ya simenti. Itha kupanganso kusakaniza kwa asphalt, kusakaniza kwa asphalt wachikuda, etc. Ndi zida zofunika pomanga misewu yayikulu, misewu yamakalasi, misewu yamatauni, ma eyapoti, ndi madoko. Tsopano aliyense akumvetsa siteshoni phula kusakaniza.
