Munyika yangu, mazhinji emidziyo inoshandiswa mukuvaka mugwagwa mukuru iasphalt, saka Asphalt kusanganisa zvirimwa 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 kweasphalt. Pamusoro pekudikanwa kweasphalt kusanganisa chirimwa chemidziyo kuti isangane nezvinodiwa zvakajairwa, chiyero chezvigadzirwa zvakakosha zvakare. Parizvino, maindasitiri emunyika yangu aripo anoratidza kuti iyo yakakura particle size yeasphalt musanganiswa inoshandiswa kumusoro kwenzira huru haigoni kudarika hafu yehupamhi hwepamusoro, uye huwandu hwehukuru hwechikamu chemusanganiswa weasphalt wepakati haugoni kudarika maviri- zvikamu zvitatu zvehupamhi hwehupamhi, uye hukuru hwehukuru hwechigadziro chechimiro hachigoni kudarika chikamu chimwe chetatu chechidimbu chimwe chete.
Kubva pane mirairo iri pamusoro, inogona kuonekwa kuti kana iri imwe hupamhi hweasphalt layer, kana chidimbu chechidimbu chemusanganiswa weasphalt yakasarudzwa yakanyanya kukura, ipapo kuvakwa kweasphalt concrete pavement kuchakanganiswawo 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.
