Sinoroader emulsified asphalt pavement engineering yakajairika michina, ikozvino yave kushandiswa zvakanyanya zvishoma nezvishoma.
Isu tese tinoziva kuti chero mudziyo usati washandiswa, mudziyo unofanirwa kutanga waongororwa kuti utarise kana kuiswa kwacho kwakajairika, wozoiswa mukushandisa. Iko kushandiswa kweyakagadziridzwa asphalt yakagadziridzwa asphalt yekugadzira michina inogona zvakare kuwedzera mwaka wepamusoro. Iyo yakagadziridzwa asphalt nematombo emvura muchina unogona kusanganiswa nedombo rakanyorova kuti riite firimu rinoramba riripo pasi pemamiriro ekunze epasi-tembiricha asphalt nedombo. Iyo viscosity yeasphalt yakaderera uye viscosity ye emulsified asphalt yakaderera. Yet firimu pasi pe10 degrees.

Tarisa muchina wakagadziridzwa emulsified asphalt gadziriso yemidziyo. Kana iyo emulsified asphalt colloid emulsion muchina ukashandiswa kwenguva yakareba, chigayo chinoputika chichava chikuru, saka panguva ino tinofanira kuchigadzirisa kuti tienderere mberi nekugadzirwa. Iri idambudziko riri nyore. Pakuongororwa kweiyo modhifita, huwandu hwese hwekugadzirisa hwakawedzerwa hunofanirwa kugadziridzwa zvichienderana nemhando yemvura yakasiyana kana uchiwedzera pH kukosha. Dambudziko rinoda kuongororwa nenyanzvi. Iyo asphalt yekugadziridza midziyo pachayo idambudziko rinogoneka, nekuti yakajairwa asphalt inewo akasiyana mativi. Paunenge uchigadzira yakagadziridzwa asphalt, kutarisisa kunofanirwa kubhadharwa kune kudiwa kwezvinhu zvakabikwa, zvinova zvakajairika asphalt uye mhando.
Zvinhu zvinofanirwa kutariswa kune yakagadziridzwa asphalt midziyo iri panguva yekuongorora. Tinofanira kushanda nemazvo maererano nemirairo. Nenzira iyi chete tinogona kuwana mhedzisiro iri nani. Kana iwe usinganzwisise chero chinhu, ndapota inzwa wakasununguka kutibata nesu munguva.
