Hauj lwm mastic asphalt tshuab

Cov cam khwb cia asphalt qhob sib tov yog complex-puas khoom lug siv rau kev tsim kho lub hom phiaj. Lub ntsiab sib txawv los ntawm lub mastic asphalt yog asphalt qhob txoj kev rau nws cov installation.

Qhuav ntawm ib tug sib tov

Muaj pes tsawg leeg ntawm cov cam khwb cia asphalt muaj tib yam li rau asphaltic ua vaj tse, tab sis sib txawv proportions ntawm kneading. Lub ntsiab Cheebtsam ntawm sib tov yog molded gravel, xuab zeb, mineral hmoov thiab bitumen. Tab sis lub sij khoom xyaw yog txawv me ntsis muaj pes tsawg leeg. Xuab zeb siv tej yam ntuj tso keeb kwm los yog feem kawm poob ntawm cov pob zeb thiab cov mineral hmoov - Ua los ntawm ib tug heev carbonate pob zeb.

Tus nqi ntawm cov bitumen thiab hmoov considerably siab tshaj uas ntawm asphaltic ua vaj tse, uas yuav ua rau lub embodiment ntawm ib tug molded yas thiab khov. Feem ntau cov manufacturers nyob rau hauv zus tau tej cov cam khwb cia asphalt ib qho kuam me me sib tov siv, uas yeej cov nqi ntawm tus txheej txheem ntawm kev tsim txoj kev nto, tab sis ib tug tsis zoo ntxim rau nws cov khoom.

yam ntxwv ntawm

Lub ntsiab kom zoo dua ntawm no hom ntawm txheej yog tiav dej kuj vim rau tag nrho cov es lub ntxeem tau qauv, li no ua lub durability thiab ncua lub Scope ntawm daim ntawv thov. Raws li cov kev siv technology tshiab uas yuav tsum tau ntawm zus tau tej cov lub neej ntawm mastic asphalt txog li ib nrab xyoo, uas yog ho ntev kev pab cuam lub neej ntawm asphalt qhob.

Cov kev siv ntawm tej mixtures tso cai rau ua txoj kev nto ntau tus thiab txo lub thickness tsis tau poob rau kev sib khi zog. Qhov no hom ntawm asphalt qhob muaj enhanced corrosive coj tus yam ntxwv thiab yog robust rau lub sij hawm variations thiab qaug zog kev puas tsuaj, raws li zoo raws li muaj peev xwm sawv ntawm tiv enormous tensile deformation cim. Mastic asphalt yog ntau resistant rau kev puas tsuaj rau cov khoom siv los yog kab ntsig studded log tsheb, muaj peev xwm mas huab kub thiab lengthy thermal raug. Nws tsis yuav tsum tau siv ntawm kev sib khi sib tov, thiab kho txheej yuav nqa tawm thaum lub sij hawm uas tsis muaj peevxwm.

shortcomings

Txawm li cas los, qhov no txheej muaj negative yam ntxwv, uas muaj xws li high raug nqi vim kev siv uas muaj zog cov nqi ntawm cov kim Cheebtsam, thiab cov yuav tsum tau ntiav kev cov txheej txheem rau stacking thiab hloov ntawm asphalt (tshwj xeeb thermo-mixers thiab tso cua sov). Ntxiv mus, vim lub high ntsiab lus ntawm asphalt paving binders raug kev txom nyem ntsuas vim hais tias ntawm cov uas muaj ib tug xav tau kev pab ntxiv ua hauj lwm rau lub compact dub gravel txheej mounted rau cov asphalt pavement.

Cov txheej txheem nws tus kheej yog tsis tshiab. Qhuav ntawm cam khwb cia asphalt yog nqa tawm nyob rau hauv ib tug tshwj xeeb cov nroj tsuag asphalt bitumomesilnyh lug, zoo ib yam li loj loj qhob mixers, raws li cov technology, zoo ib yam li qhov siv thiab ua cov pa asphalt qhob. Lub tiav lawm sib tov muaj ib tug high kub (200 C), uas yog tswj kom txog rau thaum kev siv cov khoom rau nws npaj lub hom phiaj. Thaum thauj kua asphalt yuav tsum lossi do sib tov thiab ua kom cov tshav kub uas tshwj xeeb cov cav tov tau tsim - "Kocher", uas yog thermo-mixers.

daim ntawv thov

Cam khwb cia asphalt qhob siv rau kev tsim kho ntawm tej kev loj thiab txoj lw, txoj kev thiab tus choj chaw thiab kev mus taw. Nyob rau hauv tas li ntawd, vim khov zog, nws yog siv rau waterproofing los yog ustilaniya plag tsev nyob rau hauv lub chav. Lub thoob plaws tej chaw ntawm mastic asphalt yog vim muaj lub siab siv nyob rau hauv lub kho ntawm txoj kev qhov nyob rau hauv lub txias rau lub caij ntawm subzero kub. Tom qab lub txheej yuav yooj yim ciaj sia mus rho tawm 10 degrees thiab nyob rau hauv lub qhov chaw uas yog qhov.

Tsis tas li ntawd thov mastic asphalt rau pavement coatings. Qhov no tso cai rau koj mus kom tag nrho cov zoo qualities ntawm txoj kev khiav thiab muab nws ib tug zoo nkauj daim ntawv thiab cov qauv. Los ntawm no pavement tsis sprout nyom, tsis muaj tej kab nrib pleb. Cov txheej yog tau withstand theem siab hnyav load thiab kub nco. Txawm li cas los, cov kev siv ntawm cam khwb cia mixtures nyob rau hauv qhuav ntawm paving slabs, tsis tsuas retains tag nrho cov kev pab thaj chaw ntawm asphalt, tab sis kuj tsim tshiab sawv daws yuav. Tej pavement muaj siab thermal stability thiab tej friendliness, vim hais tias cov pobzeb cua kub kub saum toj no uas tsis tso cai rau cov txheej faib rau cov ib puag ncig carcinogens.

Poured asphalt yuav muab tau yooj yim muab tshem tawm thiab rhuav, thiab tsuas pib dua. Qhov no txuag tau nyiaj rau cov kev kho. Kev siv ntawm high-zoo zus tau tej cov mastic asphalt rau paving slabs guarantees ib tug ntev lub txee lub neej ntawm lub txheej, uas, tsis zoo li los ntawm cov asphalt mus txog 100 xyoo. Pavement cam khwb cia mixtures yog pom ib qho rau kev siv nyob rau hauv tus kheej qhov chaw, vim hais tias ib theem siab ntawm kev zoo thiab tej friendliness. Cam khwb cia asphalt ua tsaug rau ib tug ntau ntawm cov pab zog thiab cov tsis tuaj kawm ntawv ntawm tsis yog zoo tagnrho rau zus tau tej cov kev taug kev pab them nqi.
