Umzi-mveliso wokuhlambulula ibhitumene kufuneka wenze iimvavanyo ezithile. Ziziphi iingongoma eziphambili zeendlela zayo zokuvavanya? Andazi ukuba uyazi kangakanani na. Kufuneka siqonde ulwazi olusisiseko ngaphambi kokuba silusebenzise. Ngoku siza kukunika inkcazo eneenkcukacha:
Isampulu yebhitumene iyafudunyezwa kwaye ihluzwe, kwaye inxalenye echaziweyo ye-anti-flaking agent yongezwa, kwaye ixutywe ngesandla okanye ngesixhobo esishukumisayo ukwenza i-agent anti-flaking ihlakazwe ngokulinganayo kwi-bitumen specimen; uvavanyo lokufudumeza ifilimu yeplastiki lwenziwa kwi-specimen yokufudumeza Ukuguga, sebenzisa inyathelo lamanzi okanye indlela yokubilisa amanzi ukuvavanya ukunamathela kwebhitumene kunye nomxube ongcolileyo we-asphalt;

Xa kuyimfuneko, sinokusebenzisa imixube ye-asphalt engazange ifudunyezwe kwaye igugile kunye neefilimu zeplastiki ukwenza iimvavanyo zokubambelela, okanye sinokusebenzisa ikhonkrithi yesamente engazange ikhulile ukuqhuba iimvavanyo zokuzinza ezithe tye ukumisela ukuxhathisa ubushushu be-agent anti-stripping. . kunesiphumo sesicelo sexesha elide.
Yenza unyango olukhawulezayo lokuguga kumxube oshushu we-asphalt usebenzisa i-anti-stripping agents; ukuqhuba untywiliselo lwamanzi iimvavanyo Marshall kunye impulsive isityuzi iimvavanyo imixube ukuvavanya uzinzo oxwesileyo lemixube asphalt.
Eyona ndlela yokuvavanya isityalo sokususa ibhitumene yile. Kufuneka senze imisebenzi esebenzayo ngokwemiyalelo, ukuze sibonise ngokupheleleyo iimpawu zayo. Inani elikhulu lobuchwepheshe obuphezulu obunxulumene nezityalo ze-bitumen decanter ziya kuhlelwa kwakhona. Wamkelekile ngokufudumeleyo ukujonga ngoku.
