Ngokuvamile, izitshalo zokuxuba itiyela zisebenza ku-asphalt, kodwa uma ukhonkolo uxutshwa kuwo, kufanele silawule kanjani imishini? Vumela umhleli akuchazele kafushane ukuthi ungalawula kanjani isitshalo sokuxuba i-asphalt ngaphansi kwezimo ezikhethekile.
Ukuze ukhonkolo oxutshwe nezixube, umthamo, indlela yokuxuba kanye nesikhathi sokuxuba kufanele kulawulwe ngokuqinile, ngoba lezi yizici ezibalulekile ezithinta ikhwalithi yomkhiqizo wokugcina. Akunakuzitshwa ngoba kusebenzisa i-CNC encane, futhi ngeke kusetshenziswe njengendlela yokonga izindleko. Ngesikhathi esifanayo, kuvinjelwe ngokuqinile ukunciphisa isikhathi sokuxuba ukuze kusheshiswe inqubekelaphambili.

Indlela yokuxuba ekhethiwe ayikwazi ukunganaki. Ukhonkolo udinga ukugaywa nge-hydrolyzed ngaphambi kokuthi uxutshwe. Ukuxuba okomile akuvunyelwe. Uma i-concrete agglomerates, ayikwazi ukusetshenziswa. Ngesikhathi esifanayo, ukuze ulawule ukuzinza kwayo, inani le-ejenti yokunciphisa amanzi noma i-air-entraining agent kufanele ilawulwe ukuze kuqinisekiswe ukuthi isitshalo sokuxuba i-asphalt singakhiqiza imikhiqizo ephezulu.
