Horumarka degdega ah ee dhismaha wadada weyn, Kordhinta baahida loo qabo bitumen, durbaan bitumen ama foosto bitumen ah ayaa ah xidhidhiyaha ugu caansan ee badbaadada iyo raaxada awgeed.

Bitumen barafaysan oo si sahlan loo qaadi karo, Si fudud loo kaydin karo iyo sifooyin kale ayaa aad loo isticmaalaa. Gaar ahaan, bitumen-ka dibadda laga keeno ee waxtarka badan leh ee lagu isticmaalo waddooyinka heerkoodu sarreeyo ayaa u badan foosto. Tani waxay u baahan tahay dhalaal degdeg ah, Ka saar foosto,mashiinka bitumen decanterawood u leh ka hortagga gabowga bitumen.

Nooca taxanaha BDdurbaan bitumen soo saaraMashiinka  ay samaysay shirkadeena waa qaab isku dhafan oo iskuleyliya. Isticmaalka gubanaya naaftada il kulaylka ah, De-barreling bitumen by hawada kulul iyo kulaylka wareejinta saxan kulaylka saliidda, dhalaalay, kululaynta, Qalabka dammaanad qaadi kara tayada kululaynta bitumen,
Kuleylka sare ee waxtarka leh, Xawaaraha soo saarista bitumen waa mid degdeg ah, Waxay leedahay sifooyinka waxtarka kuleylka sare, xawaaraha saarista bitumen ee degdega ah, xoogga shaqada oo hooseeya, wasakh la'aan, qiimaha qalabka hooseeya, meel yar oo la haysto iyo gaadiid ku habboon. Mashiinka dhalaalida bitumen-ka asphalt inta badan waxa uu ka kooban yahay sanduuqa aan fuusada lahayn, habka wax qaadista,  Hydrolic propeller, haanta tuman, naaftada gubta, qolka gubta ee ku dhex jira, nidaamka kululaynta qiiqa, nidaamka kuleylka saliida wareejinta kulaylka, bamka bitumen iyo nidaamka tuubooyinka, xakamaynta heerkulka tooska ah. Nidaamka, nidaamka xakamaynta tooska ah ee heerka dareeraha, nidaamka kontoroolka korantada, iwm. Dhammaan qaybaha waxay ku rakiban yihiin jirka qalabka saarista foosto si loo sameeyo qaab dhismeed midaysan.

Qaab-dhismeedka isku-dhafka ah ee is-kuleylka, dhalaalidda-xumbada-hawo-kuleelka iyo tignoolajiyada leexashada foosto bitumen ee qalabka bitumen de-barreling waa tignoolajiyada ugu dambeeyay ee shirkaddeena. Habka isku-dhafka ah ee is-kuleylka ayaa si fiican isugu daraya foornada saliidda kuleyliyaha ee loo isticmaalo qalabkii hore iyo jirka qalabka asphalt de-barreling. Tirada guud ee qalabka waa la dhimay, maalgelinta qalabka si weyn ayaa loo dhimay, booska ay ku jiraan qalabka iyo kharashka gaadiidka ee kala-guurka ayaa la keydiyaa. Qolka gubanaya waxaa lagu dhejiyaa gudaha qalabka, kaas oo si weyn u yareynaya luminta kulaylka waxayna hagaajinaysaa isticmaalka kulaylka.
