Asphalt inoparadzira rori imhando yemakina ekugadzira migwagwa mitema. Ndiyo midziyo mikuru mukuvakwa kwemigwagwa mikuru, migwagwa yemuguta, nhandare dzendege uye zviteshi zvechiteshi. Mudziyo uyu unonyanya kushandiswa kupfapfaidza marudzi akasiyana easphalt panzira yemugwagwa kuti asangane nezvinodiwa zvekuvaka zvemazinga akasiyana-siyana epavement kuburikidza ne layer, adhesive layer, kumusoro nezasi sealing layer, fog sealing layer, etc. Zvisinei, kupararira kwevamwe. asphalt anoparadzira marori pamusika haagutsi. Pachava nekusaenzana kugovewa kwakatwasuka. Chiitiko chinowanzoitika chekusaenzana kwakachinjika kugovera mitsetse yakachinjika. Panguva ino, mamwe matanho anogona kutorwa kuti anyatso kuvandudza lateral kufanana kweasphalt kupararira.
1. Kuvandudza chimiro chemhino
Izvi zvine zvinotevera zvinangwa: kutanga, kuchinjika kune chimiro chepombi yekupfapfaidza uye kuita kuti asphalt kuyerera kugovera kwega kwega kunoda kufanana; chechipiri, kuita chimiro uye saizi yekupfapfaidza fungidziro yechiso chepfumbu imwe chete kusangana nezvinodiwa zvekugadzira, kuwana mhedzisiro yakanaka, uye kuita Iyo asphalt inoyerera kugovera munzvimbo inosangana nezvinodiwa zvekugadzira; chechitatu ndechekugadzirisa zvinodiwa zvekuvaka kwemhando dzakasiyana dzeasphalt uye zvakasiyana-siyana zvekupararira.

2. Wedzera kukurumidza kupararira zvakakodzera
Chero bedzi kumhanya kweyakangwara asphalt inoparadzira rori ichichinja mukati meiyo inonzwisisika renji, haizove nemhedzisiro pakufanana kwelongitudinal yekupararira kweasphalt. Nokuti kana motokari inokurumidza kukurumidza, chiyero cheasphalt chinopararira pane imwe nguva inova yakakura, asi huwandu hweasphalt hunopararira panzvimbo yeyuniti hunoramba husina kuchinjwa, uye kuchinja kwekukurumidza kwemotokari kune simba guru pane kufanana kwemashure. Kana kumhanya kwemotokari kuchikurumidza, kuyerera kwenozzle imwe chete panguva yeyuniti inova yakakura, iyo yekupfapfaidza fungidziro yepamusoro inowedzera, uye nhamba yekuputira inowedzera; panguva imwecheteyo, jet velocity inowedzera, iyo asphalt kudhumhana simba inowedzera, iyo "impact-splash-homogenization" mhedzisiro inowedzerwa, uye yakatwasuka kupararira kunoitika Yakawanda yunifomu, saka kukurumidza kukurumidza kunofanirwa kushandiswa zvakakodzera kuchengetedza lateral kufanana kwakanaka.
3. Kuvandudza asphalt properties
Kana iyo viscosity yeasphalt yakakura, kuyerera kweasphalt kuchave kwakakura, jekiseni molding ichave diki, uye iyo inopindirana nhamba ichaderedzwa. Kuti ukunde kukanganisa uku, nzira yakajairika ndeyekuwedzera dhayamita yemhino, asi izvi zvinozoderedza jet velocity, kuderedza iyo "impact-splash-homogenization" mhedzisiro, uye kuita kuti kugovaniswa kwakatwasuka kusaenzana. Kuti uvandudze kushanda kwe tekinoroji yekuvaka asphalt, zvinhu zveasphalt zvinofanirwa kuvandudzwa.
4. Ita hurefu hwepombi yepombi kubva pasi inogadziriswa uye yakavharwa-loop control
Sezvo iyo spray fan angle ichakanganiswa nezvinhu zvakaita sekumhanya kwemotokari, asphalt mhando, tembiricha, viscosity, nezvimwewo, kureba pamusoro pevhu kunofanirwa kutariswa zvichibva pane ruzivo rwekuvaka uye kugadziridzwa zvichibva pane izvi: Kana kureba kwepombi yesprinkler. kubva pasi yakanyanyisa, kukanganisa kweasphalt spraying kuchaderedzwa. simba, kunetesa "impact-splash-homogenization" mhedzisiro; kureba kwepombi yekupfapfaidza kubva pasi kwakadzikira zvakanyanya, izvo zvinozodzikisa huwandu hwemapazi anopindirana asphalt spray sector. Kureba kwepombi yekupfapfaidza kunofanirwa kugadziridzwa zvinoenderana nemamiriro chaiwo ekuvandudza asphalt spraying effect.
