Cast mix ntawm asph alt pob zeb yog cov khoom sib xyaw ua ke uas tau siv dav rau kev tsim kho. Qhov sib txawv tseem ceeb ntawm cov pob zeb asph alt thiab cov pob zeb asph alt yog nws cov txheej txheem tso.

Cov muaj pes tsawg leeg ntawm cov pob zeb asph alt suav nrog cov khoom qub xws li cov pob zeb asph alt, tab sis cov proportions rau kev sib tov sib txawv. Cov khoom tseem ceeb ntawm cov cam khwb cia yog crushed pob zeb, xuab zeb, ntxhia hmoov thiab bitumen. Txawm li cas los xij, cov khoom xyaw lawv tus kheej sib txawv me ntsis hauv kev muaj pes tsawg leeg. Xuab zeb yog siv los ntawm tej yam ntuj tso keeb kwm los yog los ntawm kev tshuaj ntsuam ntawm pob zeb, thiab ntxhia hmoov yog tsim los ntawm active carbonate pob zeb.

Tus nqi ntawm bitumen thiab hmoov yog ntau dua li ntawm asph alt pob zeb, uas ua rau cov cam khwb cia version ntau ductile thiab ductile. Feem ntau cov tuam txhab siv asph alt chips hauv kev tsim cov cam khwb cia sib tov, uas tsis tas yuav txo tus nqi ntawm kev tsim txoj kev, tab sis cuam tshuam tsis zoo rau nws cov khoom.

Ntse

Qhov txiaj ntsig tseem ceeb ntawm hom txheej txheej no yog ua tiav cov dej tsis muaj dej vim yog cov khoom siv, tsis ntxeem tau, uas ua rau kom muaj zog thiab nthuav dav. Kawm txog kev siv tshuabCov kev xav tau ntau lawm, kev pab cuam lub neej ntawm cam khwb cia asph alt ncav cuag ib nrab xyoo pua, uas yog ntev npaum li qhov kev pab cuam lub neej ntawm asph alt pob zeb.

Kev siv cov khoom sib xyaw no tso cai rau koj ua kom txoj hauv kev smoother thiab txo cov tuab yam tsis poob nws cov khoom sib khi. Hom asph alt pob zeb no tau txhim kho corrosion thiab hnav-tiv taus cov yam ntxwv, tiv taus kev hloov ntawm lub cev thiab qaug zog kev puas tsuaj, thiab tseem muaj peev xwm tiv taus cov kab mob loj heev ntawm cov xwm txheej deformation. Moulded asph alt yog tiv taus ntau dua rau kev puas tsuaj los ntawm kab ntsig tsheb lossis cov log tsheb, tiv taus qhov kub thiab txias hloov mus ntev. Nws tsis tas yuav tsum tau siv lub sealing compound, thiab cov txheej tuaj yeem kho tau thaum qhov kub thiab txias.

Flaws

Txawm li cas los xij, cov txheej txheem no kuj muaj qhov tsis zoo, uas suav nrog cov nqi tsim khoom siab vim yog siv cov khoom siv kim kim, nrog rau kev xav tau siv cov cuab yeej tshaj lij rau kev tso thiab hloov asph alt (tshwj xeeb thermal mixers thiab heaters). Tsis tas li ntawd, vim muaj cov ntsiab lus siab ntawm bitumen, cov khoom sib khi ntawm txoj kev ntog raug kev txom nyem, uas yuav tsum tau ua haujlwm ntxiv ntawm kev nias dub crushed pob zeb mus rau txheej txheej asph alt.

Txoj kev nws tus kheej tsis yog tshiab. Kev tsim cov cam khwb cia asph alt yog nqa tawm ntawm asph alt qhob nroj tsuag tshwj xeebbitumen-sib tov cov qauv, zoo ib yam li cov pob zeb loj loj, siv cov cuab yeej zoo ib yam li kev tsim cov pa asph alt pob zeb. Cov sib tov tiav lawm muaj qhov kub thiab txias (los ntawm 200 C), uas yog tswj kom txog thaum cov khoom siv rau nws lub hom phiaj. Thaum thauj cov ncuav asph alt, nws yog ib qho tsim nyog yuav tsum tsis tu ncua sib tov sib xyaw thiab tswj kom muaj qhov kub thiab txias, uas cov tshuab tshwj xeeb tau tsim - "kochers", uas yog cov thermo-mixers.

Daim ntawv thov

Cast asph alt pob zeb yog siv rau kev tsim kho kev loj thiab kev loj, txoj kev thiab choj pavements thiab cov neeg taug kev. Tsis tas li ntawd, vim nws cov khoom viscous, nws yog siv rau waterproofing lossis flooring hauv chav. Moulded asph alt tau txais txiaj ntsig dav vim nws siv tau yooj yim hauv kev kho cov pits hauv lub caij txias ntawm qhov kub qis. Tom qab tag nrho, cov txheej no yooj yim tiv taus txog li 10 degrees thiab yooj yim sau qhov chaw ntawm lub qhov.

Moulded asph alt kuj yog siv rau txheej txheej pavement. Qhov no tso cai rau koj txuag tag nrho cov txiaj ntsig zoo ntawm txoj kev taug thiab muab nws cov duab zoo nkauj thiab cov qauv. Nyom tsis loj hlob los ntawm txoj kev taug kev zoo li no, cov kab nrib pleb tsis tshwm sim. Cov txheej no muaj peev xwm tiv taus qhov hnyav hnyav thiab qhov sib txawv ntawm qhov kub thiab txias. Txawm li cas los xij, kev siv cov cam khwb cia hauv kev tsim cov paving slabs tsis tsuas yog khaws tag nrho cov txiaj ntsig ntawm asph alt, tab sis kuj tsim cov tshiab. Xws li ib tug pavement tau nce tshav kub kuj thiab ib puag ncig tus phooj ywg, vim hais tiasCov cua kub ntawm cov pobzeb yog siab dua, uas tiv thaiv cov txheej ntawm kev tso cov khoom carcinogenic rau hauv ib puag ncig.

Moulded asph alt yooj yim tshem tawm thiab rhuav tshem, thiab yooj yim rau rov nruab. Qhov no txuag nyiaj ntawm kev kho. Kev siv cov cam khwb cia zoo asph alt pob zeb rau kev tsim cov paving slabs lav lub neej ntev ntawm cov txheej, uas, tsis zoo li asph alt nws tus kheej, tuaj yeem ncav cuag 100 xyoo. Lub cam khwb cia-siv pavement yog qhov kev xaiv zoo tshaj plaws rau kev siv nyob rau hauv cov chaw ntiag tug, vim tias nws yog qhov txawv los ntawm cov qib siab zoo thiab ib puag ncig tus phooj ywg. Vim muaj ntau yam khoom muaj txiaj ntsig thiab tsis muaj qhov tsis zoo, cam khwb cia asph alt yog qhov zoo tagnrho rau kev tsim cov paving surfacing.
