Shaabada slurry waa in la isticmaalo qalabka makaanikada si loogu daro daamur emulsified si habboon loo darajeeyey, isku-darka isku-darka ah iyo kuwa fiican, biyaha, buuxinta (sibidhka, lime, dambaska duulista, budada dhagaxa, iwm.) iyo waxyaabaha lagu daro isku dhafka slurry iyadoo loo eegayo saamiga loo qaabeeyey oo si siman u faafay waxay ku taal dusha wadada asalka ah. Ka dib markii la duubo, demulsification, kala-soocidda biyaha, uumiga iyo adkeynta, waxaa si adag loogu daraa dusha sare ee wadada asalka ah si ay u sameeyaan cufan, xoog leh, xidhid u adkaysta iyo shaabadda waddada, taas oo si weyn u hagaajinaysa waxqabadka waddada.
Tignoolajiyada shaambada slurry waxay ka soo ifbaxday Jarmalka dabayaaqadii 1940-meeyadii. Dalka Maraykanka, adeegsiga shaabada slurry ayaa 60% ka ah sagxadaha waddooyinka madow ee dalka, waxaana la ballaariyay baaxadda isticmaalkeeda. Waxay door ka ciyaartaa ka-hortagga iyo hagaajinta cudurrada sida gabowga, dildilaaca, dabacsanaanta, dabacsanaanta, iyo godadka waddooyinka cusub iyo kuwa duugga ah, taasoo ka dhigaysa waddada oogada biyaha mid aan biyuhu ahayn, ka-hortagga barafka, fidsan, iyo xirashada u adkeysaneysa si degdeg ah.

Shaabada slurry sidoo kale waa habka dayactirka ka hortagga ah ee dhismaha daweynta dusha sare. Laamiyadii hore ee daamurku waxay badanaa leeyihiin dildilaacyo iyo godadka. Marka dusha sare la xidho, isku darka shaabadda asphalt-ka ee emulsified ayaa lagu faafiyaa lakab khafiif ah oo ku yaal laamiga oo la adkeeyo sida ugu dhakhsaha badan si loo ilaaliyo laamiga shubka ah. Waa dayactir iyo dayactir loogu talagalay in lagu soo celiyo shaqadii laamiga si looga hortago burbur kale.
Dilaaca qunyar-jilicda ama dhexdhexaadka ah ee isku-dhafka ah ee loo isticmaalo shaabadda slurry waxay u baahan tahay asfalt ama kakoob polymer ah oo ku saabsan 60%, iyo ugu yaraan waa inuusan ka yarayn 55%. Guud ahaan, anionic emulsified asphalt waxa uu leeyahay ku dheggan liidata ee alaabta macdanta iyo waqti dheer qaabaynta, waxaana inta badan loo isticmaalaa isku darka alkaline, sida nuuradda. Asphalt cationic emulsified wuxuu leeyahay ku dheggan wanaagsan isku-darka aashitada waxaana inta badan loo isticmaalaa isku-darka acidic, sida basalt, granite, iwm.
Xulashada emulsifier-ga asphalt, oo ka mid ah maaddooyinka ku jira daamurka la sumeeyey, ayaa si gaar ah muhiim u ah. Emulsifier asphalt wanaagsan kaliya ma xaqiijin karo tayada dhismaha laakiin sidoo kale wuxuu badbaadin karaa kharashyada. Markaad dooranayso, waxaad tixraaci kartaa tilmaamayaasha kala duwan ee emulsifiers asphalt iyo tilmaamaha isticmaalka alaabta u dhigma. Shirkadeena waxay soo saartaa noocyo kala duwan oo ah emulsifiers asphalt oo ujeedo badan leh. Haddii aad wax su'aalo ah qabtid, fadlan kala tasho adeegga macaamiishayada.
Shaabada dheecaanka daamur ee daamur leh ayaa loo isticmaali karaa ka hortagga ilaalinta waddooyinka sare iyo kuwa hoose, sidoo kale waxay ku habboon tahay shaabadda hoose, lakabka xirashada ama lakabka ilaalinta ee waddooyinka cusub ee la dhisay. Hadda waxaa sidoo kale loo isticmaalaa waddooyinka waaweyn.
Kala-soocidda shaabaddii slurry:
Marka loo eego qiimeynta kala duwan ee agabka macdanta, shaabadda slurry waxaa loo qaybin karaa shaabad fiican, shaabad dhexdhexaad ah iyo shaabad aan dhab ahayn, oo ay matalaan ES-1, ES-2 iyo ES-3 siday u kala horreeyaan.
Marka loo eego xawaaraha furitaanka taraafikada
Marka loo eego xawaaraha furitaanka taraafigga [1], shaabadda slurry waxaa loo qaybin karaa si degdeg ah u furan nooca taraafigga nooca slurry seal iyo nooca slurry-ga ee gaabiska u furan.
Marka loo eego haddii wax-beddelayaasha polymer lagu daro
Marka loo eego haddii wax-ka-beddelayaasha polymer lagu daro, shaabadda slurry waxaa loo qaybin karaa shaabad dhalaalaysa iyo shaabad dheecaan ah oo la beddelay.
Marka loo eego sifooyinka kala duwan ee asphalt emulsified
Marka loo eego sifooyinka kala duwan ee daamurka emulsified, shaabadda slurry waxaa loo qaybin karaa shaabad dareere ah oo caadi ah iyo shaabad dareere ah oo wax laga beddelay.
Marka loo eego dhumucda dhumucda, waxa loo qaybin karaa lakabka xidhidhiyaha ganaaxa (lakabka I), lakabka xidhidhiyaha dhexdhexaadka ah (nooca II), lakabka xidhidhiyaha qalafsan (nooca III) iyo lakabka dhumucsan (nooca IV).
