Kwagura screed nikintu cyingenzi kuri paweri ya asfalt ituma sisitemu ya screed ihinduka kuburyo butandukanye bwa pave.Kwagura screed ifata kumpera yicyapa nyamukuru kugirango yongere neza ubugari bwuzuye.Igizwe nibyuma byerekana ibyuma bihujwe na screed nkuru, ibyuma bisusurutsa hamwe na vibrateri kugirango bihuze sisitemu nyamukuru, hamwe na hydraulic uburyo bwo kwagura no gukuramo ibyapa.Intego nyamukuru yo kwagura screed ni ugutanga ibintu byoroshye mugutunganya ubugari udakeneye sisitemu nshya ya screed kuri buri bugari.Ukoresheje guhinduranya kwaguka kwerekanwa uburebure butandukanye, pave imwe ya asfalt irashobora gukora umuhanda wubugari bwinshi.Ibi bituma abashoramari bakoresha imashini imwe mumishinga itandukanye ya pave kugirango bongere igiciro nigihe neza.Kurambura kwerekanwa bifatanye kuruhande rumwe kugeza ku isahani nkuru ya paveri, no kurundi ruhande ku kuboko kwa telesikopi ishobora kwaguka no gusubira inyuma.Isahani yerekana ibikoresho igura igice cyagutse kandi igahuza icyerekezo nyamukuru, hamwe na hoteri, vibrateri, hamwe nigitambambuga cyo guhuza ibice byingenzi.Iyo yaguwe byuzuye, kwaguka kwerekanwa bihuza ntaho bihuriye na ecran nkuru kugirango itange ubuso bumwe kandi buhoraho bwerekanwe hejuru yubugari bwuzuye bwa pave.Kwinjizamo ibice byuzuzanya bigizwe nigice cyagutse bituma habaho gukomeza, guhuza kaburimbo imwe, ubwinshi, hamwe nuburyo butandukanye mubugari butandukanye.
Ubukorikori bushobora gutanga neza neza asifalt pave yagura screed hafi ya yose izwi cyane ya asifalt yamashanyarazi, nka VOGELE, DYNAPAC, CAT nibindi.Hamwe nubushobozi bwo kwaguka no kugabanya sisitemu ya screed kugirango ihuze ubugari bwa pave isabwa, pave imwe ya asfalt yunguka byinshi kandi byoroshye.Ubu bushobozi butanga ikiguzi nigihe cyo kuzigama kubasezeranye nabubaka umuhanda.Ikirambuye cyagutse, hamwe niteraniro ryibanze rya plaque, bifasha asifalt pave gukemura ibintu byinshi byimishinga ya kaburimbo.Hariho ubwoko bubiri bwaguka screed, bumwe nubwoko bwa hydraulic butuma habaho gukora ubugari butandukanye bwa pave hagati ya 1,1m na 9.5m, inyungu zayo nuburyo bworoshye kubugari butandukanye bwa pave;ubundi nuburyo bwubukanishi bugizwe nubugari bukoreshwa cyane cyane mubikorwa byigihe kirekire byubaka hamwe na burigihe, ubugari bwa pave nini na radiyo nini kuva bashoboye gucunga ubugari bwa pave hagati ya 2,5m kugeza 16m bakoresheje imigereka yinyongera.
