Munyika yedu, mazhinji emidziyo inoshandiswa mukuvaka mugwagwa mukuru asphalt, saka asphalt kusanganisa miti iri kukura nekukurumidza. Nekudaro, nekukurumidza kukura kwehupfumi hwenyika yangu, matambudziko neasphalt pavement ari kuwedzera zvishoma nezvishoma, saka zvinodiwa zvemusika zveasphalt zviri kuwedzera uye zvakanyanya.

Pane zvinhu zvakawanda zvinokanganisa kunaka kwekushandiswa kweasphalt. Pamusoro pemichina inosangana nezvinodiwa zvakajairwa zveasphalt kusanganisa chirimwa, chikamu chezvakagadzirwa chinhu chakakoshawo. Mitemo yeindasitiri yenyika yangu yazvino inotaura kuti saizi yemusanganiswa weasphalt unoshandiswa muchikamu chepamusoro chemugwagwa mukuru haugone kudarika hafu yehukobvu, ukuru hwemusanganiswa uri pakati pepakati haugone kudarika hafu yeukobvu hwemaviri- chidimbu chetatu, uye ukuru hwechimiro chechimiro hachikwanise kudarika ukobvu hwakafanana. chikamu chimwe chete muzvitatu chemutsetse.
Zvinogona kuonekwa kubva pamirau iri pamusoro apa kuti kana iri asphalt layer yehumwe ukobvu, iyo particle size yeyakasarudzwa asphalt musanganiswa yakanyanya kukura, iyo ichavawo nemigumisiro yakakura pakuvakwa kweasphalt concrete pavement. Panguva ino, chikamu chezvakagadzirwa zvinofanirwa kutariswa. Tinofanira kuongorora akawanda akaunganidzwa masosi sezvinobvira kana zvine musoro. Mukuwedzera, muenzaniso weasphalt kusanganisa chirimwa zvakare chimwe chezvinhu zvinofanirwa kutariswa.
Kuti ive nechokwadi chemhando yekugadzira, vashandi vanofanirwa kunyatsoongorora uye kuongorora zvigadzirwa. Kusarudzwa uye kutsunga kwezvinhu zvakasvibirira zvinoda kuenderana nezvinodiwa zvechimiro chenzira uye kushandiswa kwehutano, kusanganiswa nemamiriro chaiwo ekupa, kusarudza zvinhu zvakakodzera kuitira kuti zviratidzo zvezvinhu zvakasvibiswa zvigone kuzadzisa zvinodiwa.
