Cov txheej txheej saum npoo yog siv los txo tus neeg sawv cev uas tuaj yeem ua ib nrab lossis tag nrho rov ua haujlwm ntawm cov hnub nyoog asphalt rau cov laus asphalt pavement. Los ntawm kev nkag mus ntawm tus neeg sawv cev txo qis, nws nkag mus rau hauv asphalt nto txheej mus rau qhov tob thiab cuam tshuam nrog cov hnub nyoog asphalt muab tshuaj. Cov tshuaj tiv thaiv polymerization tshwm sim, ua rau cov khoom ntawm cov hnub nyoog asphalt mus rau qhov kev hloov pauv rov qab, rov ua kom yooj yim, txo cov brittleness, thiab tib lub sijhawm tiv thaiv tsis muaj asphalt kom ncua kev laus. Cov txheej txheej saum npoo yog tsim rau cov pavements qhov chaw asphalt pavement yog pom tseeb tias kev laus, thiab cov pavement muaj ntau qhov sib txawv me ntsis thiab xoob hauv zos. Muaj ob hom txheej txheej, ib qho yog txheej txheej pos huab thiab lwm yam yog cov txheej txheem txo tus neeg sawv cev. Niaj hnub no peb yuav tsom mus rau kev nkag siab txog huab cua foob txheej.

Tom qab 3-6 xyoo ntawm kev siv, asphalt pavement pib muaj hnub nyoog vim muaj yam xws li tsheb thauj khoom, ultraviolet rays, thiab dynamic dej yaig. Cov pavement feem ntau raug kev txom nyem los ntawm micro tawg, xoob xoob xoob xoob, thiab lwm yam kab mob. Yog tias tsis kho raws sijhawm, nws yuav Tom qab lub caij los nag, cov kab nrib pleb hnyav dua, qhov pits, hloov pauv thiab lwm yam kab mob yuav tshwm sim, uas tsis tsuas yog ua rau cov nqi kho mob ntau dua, tab sis kuj feem ntau ua tsis tiav cov txiaj ntsig zoo.
Fog seal txheej thev naus laus zis siv lub tsheb sib kis tshwj xeeb los txau cov txheej nyias nyias ntawm cov emulsified heev permeable asphalt los yog hloov emulsified asphalt rau ntawm asphalt nto los tsim cov txheej txheem dej nruj kom kaw txoj kev nto thiab tiv thaiv nws muaj txoj haujlwm ntawm seeping thiab kho me me. tawg, thiab nce lub zog sib txuas ntawm asphalt pavement aggregates.
Raws li ib qho ntawm cov kev siv tau zoo tshaj plaws rau kev tiv thaiv thaum ntxov ntawm txoj kev loj, pos huab txheej txheej yog kev tiv thaiv kev siv thev naus laus zis ntawm asphalt pavement feem ntau siv hauv cov teb chaws tsim, thiab nws kuj tau txhawb nqa thiab siv hauv peb lub teb chaws. Tus yuam sij rau huab foob tshuab yog kom muaj cov khoom siv zoo emulsified asphalt txau thiab cov ntaub ntawv emulsified asphalt. Tam sim no, peb lub tuam txhab tuaj yeem tsim cov cuab yeej siv tshuaj tsuag thiab emulsified asphalt haum rau pos huab sealing thev naus laus zis, uas tau tshem tawm cov teeb meem rau kev tsim kho ntawm cov tshuab no.
Fog foob feem ntau yog siv rau ntawm txoj kev nrog lub teeb rau nruab nrab nplua nplua los yog xoob. Fog sealing tuaj yeem siv rau ntawm txoj kev uas muaj tsheb loj lossis me me. Fog sealing txheej tuaj yeem tsim los ntawm kev txau, txheej txheej, khawb thiab lwm yam txheej txheem. Nws raug nquahu kom siv cov txheej txheem ob zaug. Tom qab lub hauv paus saum npoo tau ntxuav, pib thawj zaug ntawm kev tsim kho kom ntseeg tau tias cov xim tuaj yeem nkag mus rau hauv cov pores capillary ntawm asphalt nto kom kaw cov capillary pores, tsim cov txheej dej tsis muaj dej, qhib cov txheej asphalt, thiab txhim kho kev ua haujlwm ntawm asphalt nto; tom qab ntawd siv daim ntawv thib ob kom paub meej tias cov ntsiab lus tsis tau Siv cov xim pleev xim rau saum npoo.
Lub tuam txhab Sinosun muaj cov cuab yeej siv ua haujlwm tshaj lij thiab pab pawg tsim kho kom paub tab. Cov neeg siv khoom xav tau txais tos tuaj xyuas peb lub tuam txhab!
