Ibasphalt distributor tshebyog ib lub tsheb tshwj xeeb uas tsis tseem ceeb rau txoj kev loj thiab txoj kev hauv nroog. Nws lub luag haujlwm tseem ceeb yog txhawm rau tshuaj tsuag cov kua asphalt sib npaug, ntau npaum li cas thiab meej rau ntawm txoj kev hauv paus, txheej txheej txheej thiab ntau yam txheej txheem txheej txheem hauv kev ua raws li cov qauv kev tsim kho. Nws npog tag nrho lub neej ntawm kev tsim kho tshiab, kev tsim kho tshiab thiab kev nthuav dav, thiab kev saib xyuas txhua hnub, nrog rau kev ua haujlwm siab, cov phiaj xwm kev ua haujlwm thoob plaws ntau txoj kev- engineering scenarios.
Hauv kev tsim kho tshiab, nws ua peb txoj haujlwm tseem ceeb. Qhov thib ib yog prime-coat spraying. Rau txoj kev hauv paus xws li cement-stabilized macadam thiab txiv qaub-av, tom qab lub hauv paus curing thiab tsim, emulsified asphalt los yog kua asphalt yog sprayed kom asphalt nkag mus rau hauv qhov hws ntawm lub hauv paus nto, ntsaws ruaj ruaj hauv paus tawg thiab xauv hauv cov dej noo. Lub caij no, nws ua tiav kev sib raug zoo ntawm lub hauv paus thiab tom qab asphalt nto txheej thiab tiv thaiv interlayer voids thiab tev. Qhov thib ob yog tack-coat spraying. Nws yog tsuas yog siv ntawm asphalt structural txheej, ntawm cov pob qij txha ntawm cov qub thiab tshiab pavements, nrog rau ntawm txoj kev sib tshuam thiab nthuav seem. Los ntawm kev txau cov txheej txheej asphalt, nws khi cov txheej txheej sab saud thiab sab qis rau hauv ib qho tseem ceeb thiab tshem tawm cov pavement delamination, hloov chaw thiab tawg. Qhov thib peb yog qis-foob tshuaj tsuag. Tom qab ua tiav lub hauv paus thiab ua ntej kev tsim kho saum npoo av, lub foob tsis muaj dej yog siv los thaiv cov dej nag los ntawm kev nkag mus rau hauv lub hauv paus thiab stabilize subgrade cov qauv.
Hauv cov phiaj xwm kev tu vaj tse, asphalt distributor tsheb thauj khoom muaj kev siv dav dua thiab ua raws li cov cuab yeej tseem ceeb rau kev tiv thaiv kev taug kev. Rau cov laus pavements raug kev txom nyem los ntawm micro-cracks, nto loosening, dej infiltration thiab aging, pos huab-seal operations yuav ua tau. Low-pressure fine asphalt spraying fills pavement micro-cracks, seals de pores, restores pavement waterproofness and integrity, and slows pavement aging. Rau cov pavement puas me ntsis, nws tuaj yeem ua haujlwm ua ke nrog kev sib sau ua ke sib txuas kom ua tiav hauv paus-ntev rau slurry seals thiab chip seals, kho pavement hnav thiab txhim kho kev tiv thaiv kev ua haujlwm. Thaum lub sij hawm milling-and-resurfacing, tack-coat asphalt yuav tsum tau txau los ntawm asphalt distributor tsheb mus rau milled pavement bases los tsim kev sib raug zoo substrates rau tshiab asphalt paving.
Tshaj li kev tsim kho txoj kev loj, asphalt distributor tsheb txhawb nqa ntau yam haujlwm tshwj xeeb. Lawv ua tiav asphalt-bonding-txheej txheej kev tsim kho rau txoj kev hauv nroog, txoj hauv kev hauv zej zog, kev ua haujlwm hauv tsev kawm ntawv thiab chaw nres tsheb-chav paving, nrog rau cov dej tsis zoo-asphalt txau rau cov choj decks thiab qhov av pavements. Cov tsheb me me asphalt distributor tsheb tuaj yeem ua tau yooj yim ua cov txheej txheem asphalt nthuav dav rau kev txhim kho nyob deb nroog thiab kev txhim kho ua liaj ua teb. Qee lub tsheb thauj khoom ntau yam tuaj yeem txau cov ntaub ntawv tshwj xeeb suav nrog kev hloov kho asphalt thiab roj hmab asphalt kom ua tau raws li kev tsim kho kev tsim kho rau txoj kev loj, xa cov kev daws teeb meem asphalt-txhaum tag nrho rau kev tsim kho thiab tu.
