Ku saabsan laamiga asphalt-ka ee la beddelay ee la dami karo faham faahfaahsan
Sida soo saaraha xirfadle ah Sinoroader, waxaan ku siin doonaa nooca daalacashada wadada laami ah emulsified, kaas oo ah wadarta ugu weyn ee cufnaanta bilowga ah, buufinaya lakabka emulsion ka dib kala firidhsan, buufin emulsion ah, iyo compacting qaab dhismeedka laamiga tallaabo tallaabo. Waxay ku habboon tahay waddooyinka sare iyo sare, waxaana sidoo kale loo isticmaali karaa lakabka isku xirka ee laamiga ama saldhigga.
Sababo la xiriira porosity weyn ee nooca irbadda asphalt emulsified, dusha sare waa ay fududahay in la dhex geliyo saldhigga, sidaas darteed alaabta laami iyo shaabadeynta ama lakabka waa in la dhigo. Sida in la jeexjeexo saldhigga hoose ee adag, sida lakabka daboolka ah. Marka loo isticmaalo sida lakabka isku-xirnaanta, walxaha iyo dusha sare lama xiri karo.
Nooca gelitaanka asphalt-ka la damiyay ayaa ah doorashada dhismaha xilliga qalalan iyo kuleylka. Waa in ay ahaataa xilli-roobaadka, nus bilood ka hor heerkulka sare uu ka hooseeyo 15 ℃, sidaas darteed waxaa lagu duri karaa iyada oo socodka lakabka qaab-dhismeedka furan si ay u wadaan rogid, si buuxda u sameeyey ka hor xilliga.
Isku darka daamurka daamur ee daamur ah waa in lagu doortaa xagal, oo la tuujiyey dhagax adag oo la isku dhejiyey, marka quruuruxdu jabto, dusha sare ee burburintu waxay ka weyn tahay 40%. Baaxadda cabbirka lakabka ugu weyni waa mid aan ka yarayn 50% wadarta qiimaha. No dusha lakabka isku qasan daamur emulsified daamur, dhamaadka dhismaha, 1000㎡ kasta oogada wadada waa in ay ahaataa 2 ~ 3 cubic mitir oo kale, wadar ahaan ganaax ka dib markii lakabka ah ee walxaha shaabadeynta la sifooyin la mid ah, waayo, daawaynta horudhac ah.
