Munyika yangu, mazhinji emidziyo inoshandiswa mukuvaka migwagwa mikuru iasphalt, saka zvirimwa zvekusanganisa asphalt zvakagadzirawo nekukurumidza. Zvisinei, pasi pemamiriro ekukurumidza kwehupfumi munyika yangu, matambudziko easphalt pavement akawedzera zvishoma nezvishoma, saka zvinodiwa zvemusika zveasphalt quality zvave zvakakwirira uye zvakakwirira.

Pane zvinhu zvakawanda zvinokanganisa kunaka kwekushandiswa kweasphalt. Pamusoro pekudikanwa kweasphalt kusanganisa chirimwa chemidziyo kuti isangane nezvinodiwa zvakajairwa, chiyero chezvigadzirwa zvakakosha zvakare. Parizvino, maindasitiri emunyika yangu aripo anoratidza kuti saizi yemusanganiswa weasphalt unoshandiswa muchikamu chepamusoro chemugwagwa mukuru haugone kudarika hafu yehupamhi, uye saizi yepakati yemusanganiswa weasphalt haigone kudarika zvikamu zviviri muzvitatu zvehupamhi. yehupamhi, uye ukuru hwechigadziro chechimiro hachigoni kudarika chikamu chimwe chete muzvitatu chechidimbu chakafanana.
Kubva pane mirairo iri pamusoro, inogona kuonekwa kuti kana iri imwe hupamhi hweasphalt layer, kana chidimbu chechidimbu chemusanganiswa weasphalt yakasarudzwa yakanyanya kukura, ipapo kukanganisa pakuvakwa kweasphalt concrete pavement yakakura zvikuru. Panguva ino, kana iwe uchida kuita chiyero chakaringana chemidziyo, unofanirwa kuedza kuongorora zvakaunganidzwa zviwanikwa zvakanyanya sezvinobvira. Uye zvakare, iyo modhi yeasphalt yekusanganisa michina zvakare chimwe chezvinhu zvinoda kutariswa.
Kuti tive nechokwadi chemhando yekugadzirwa kwemigwagwa, vashandi vanofanira kunyatsoongorora uye kuongorora zvigadzirwa. Kusarudzwa uye kutsunga kwezvinhu zvakasvibirira kunofanirwa kuve kwakavakirwa pane zvinodiwa zvepavement chimiro uye mhando yekushandiswa, uyezve yasanganiswa neiyo chaiyo yekugovera mamiriro ekusarudza zvinhu zvakanakisa kuitira kuti zvese zvinongedzo zvezvakagadzirwa zvikwanise kuzadzisa zvinodiwa.
