1. Tembiricha yekugadzira asphalt pavement inowanzoita 135 ~ 175 ℃. Usati wagadzira asphalt yekugezesa, zvinodikanwa kubvisa marara pachigadziko chekufamba kuti uve nechokwadi chekuti chigadziko chepavement chaoma uye chakachena. Panguva imwecheteyo, zvinodikanwa kuve nechokwadi chekunzwisisa kwehuremu uye ukobvu hwepasi pavement, iyo inoisa yakakosha nzvimbo yeasphalt paving.

2. Kupisa kwekutanga kwekumanikidzwa kwekubatanidza kunowanzo 110 ~ 140 ℃. Mushure mekudzvinyirirwa kwekutanga, vashandi vehunyanzvi vanofanirwa kutarisa flatness uye arch yemugwagwa wepavement, uye kugadzirisa chero matambudziko nekukasira. Kana paine shanduko yekuchinja panguva yekutenderedza nzira, unogona kumirira kusvika tembiricha yadonha isati yakunguruka. Kana mitswe yakachinjika ikaonekwa, tarisa chikonzero uye tora matanho ekugadzirisa nenguva.
3. Tembiricha yere-pressing link inowanzoita 120~130℃. Nhamba ye rollings inofanira kunge inopfuura ka6. Nenzira iyi chete inogona kugadzikana uye kusimba kwepavement kuvimbiswa.
4. Tembiricha pakupera kwekumanikidza kwekupedzisira kunofanirwa kunge kwakakura kupfuura 90 ℃. Kudzvinyirirwa kwekupedzisira ndiyo nhanho yekupedzisira yekubvisa mavhiri mamaki, kukanganisa uye kuona kuti iyo yepamusoro layer ine yakanaka flatness. Sezvo kusungirirwa kwekupedzisira kunoda kubvisa kusaenzana kwakasara kubva pachigadziko chepamusoro panguva yekugadzirisa zvakare uye kuve nechokwadi kuti flatness yemugwagwa wepamusoro, musanganiswa weasphalt unodawo kugumisa kusungirirwa pane imwe nzvimbo yakakwirira asi kwete yakanyanya kupisa.
