Ib qho asphalt qhob cog ntxiv cov tshuab asphalt sib xyaw los ntawm cov khoom siv raw los ua tiav cov ntaub ntawv tiav. Nws qhov yog sib npaug rau lub Hoobkas me me. Hais txog tag nrho cov txheej txheem ntau lawm ntawm cov asphalt tsob nroj, peb taw qhia cov khoom siv zoo rau kev ua kom zoo nkauj, yog tus txiv neej ib txwm muaj, cov khoom siv, cov ntaub ntawv thiab ib puag ncig. Nruj kev tswj hwm cov kev tswj hwm cov yam ntxwv ywj siab txog cov xwm txheej no, hloov tom qab tshuaj xyuas rau cov txheej txheem tswj, thiab hloov los ntawm kev tswj hwm cov txiaj ntsig tau los tswj cov yam ntxwv. Tam sim no cov ntsiab lus tseem ceeb tau hais raws li hauv qab no:

Kev xaiv cov khoom lag luam loj loj Kev sib xyaw, paving, thiab dov tawm yog peb cov txheej txheem tseem ceeb ntawm kev ua kom mechanized tsim. Asphalt qhob ob cov khoom siv yog qhov tseem ceeb hauv kev txiav txim siab kev kawm thiab ua tau zoo. Nws cov khoom sib xyaw yog feem ntau muab faib ua ob pawg, uas yog kev txuas ntxiv mus ntxiv thiab sib quas ntus. Vim yog cov ntaub ntawv tshwj xeeb ntawm cov khoom siv raw, high-qib kev hillways tsis txhob siv hom kev txuas ntxiv mus thiab xav tau cov hom yuam kev sib txawv. Muaj ntau ntau hom kev sib xyaw asphalt tov khoom siv, nrog cov sib xyaw sib txawv thiab cov plua plav tshem tawm, thiab cov chaw sib txawv.

Kev tsom xam ntawm ib txwm muaj kev txhaum hauv asphalt sib tov nroj tsuag /

hauv cov khoom siv asphalt ua kom paub meej cov khoom siv zoo thiab txhim kho kev ua tau zoo. Hauv kev tsim kho ntawm kev loj hlob hauv tsev qib high-qib kev loj, yuav luag txhua tus neeg asphalt sib tov nroj tsuag yog siv. Cov kev qhia tshwj xeeb tshaj yog 160 teev. Cov peev txheej kev nqis peev yog loj thiab yog ib qho tseem ceeb heev ntawm kev tsim kho technology. Kev ua ke ntau xyoo ntawm kev paub hauv asphalt qhob kev tsim khoom, ua kom muaj kev sib xyaw ua ke ntawm kev txhim kho asphalt.

Asphalt sib xyaw ua ke tau cov khoom siv yog ib qho kev faib ua feem ntawm kev nqis peev hauv asphalt sib xyaw cov nroj tsuag. Nws tsis tsuas yog cuam tshuam rau kev tsim ib txwm muaj, tab sis kuj txiav txim siab ncaj qha ntawm kev ua kom zoo li asphalt tov cov khoom siv yuav tsum yog kev tshawb fawb thiab kev xaiv cov zis txhua xyoo. Yog tias tus qauv loj heev, nws yuav ua rau cov nqi peev thiab txo cov khoom siv ua tau zoo ntawm polyurethans cov khoom lag luam; Yog tias cov qauv khoom siv tsawg dua, cov zis yuav tsis txaus, ua rau tsis muaj peev xwm txhim kho kev siv tau zoo, yog li lub sijhawm ua haujlwm ntev. , Kev lag luam tsis zoo, cov neeg ua haujlwm pabcuam tseem muaj zog ua kom qaug zog. Asphalt sib xyaw ua ke hauv qab no hom 2000 feem ntau yog siv rau txoj kev tsim qauv hauv zos xws li kev loj, thiab txoj kev loj hauv lub teb chaws. Feem ntau cov haujlwm no muaj kev tsim kho nruj.

Ntawm cov txheej txheem kev tsim kho ntawm tam sim no ua tiav thiab npaj siab, ntau dua 95% yog ib nrab teeb tsa kev ua haujlwm. Txoj kev pua ntawm txoj kev no muaj qhov zoo hauv cov nqe lus ntawm kev siv tus nqi thiab load-cov kabmob, tab sis nws yog nquag rau tawg, loosening, slurry, thiab voiding. , Subsidence, tsis txaus subgrade muaj zog, subgrade swb thiab lwm yam kab mob sib sib sib nqus. Nws tsis yooj yim los kho cov kab mob sib sib zog nqus. Cov kev npaj ib txwm muaj feem ntau: tsis kho cov kab mob sib sib zog nqus nyob rau hauv thaum ntxov thiab cia rau lawv tsim; thaum lub rooj kab mob sib sib zog nqus tau rau qee yam, npog lawv lossis kev pua chaw; Thiab thaum lub rooj kab mob sib sib zog nqus tau txaus cuam tshuam rau kev tsim kho, thiab muaj txiaj ntsig zoo, cuam tshuam rau ib puag ncig, cuam tshuam rau ib puag ncig kev ua haujlwm, thiab cov khoom siv loj heev, kev coj noj coj ua tau los ntawm txoj kev muaj zog, thiab cov khib nyiab loj, thiab cov kev coj ua loj thiab muaj txiaj ntsig zoo ntawm txoj kev tau ua ib qho tshiab ntawm cov ncauj lus.

[1] .Hot Asphalt Sib xyaw yog tsim los ntawm kev sib sau ua ke, hmoov thiab asphalt. Kev tswj hwm cov khoom siv raw tsuas yog koom nrog cov khoom siv asphalt, thiab kev lag luam asphalt ntawm Asphalt cov ntaub ntawv, thiab tshuaj xyuas cov khoom lag luam asphalt) Kuaj cov hnoos qeev ntawm txhua pob ntawm asphalt tuaj yeem tshawb xyuas cov ntawv sau tseg, cov ntaub ntawv khaws cia, thiab ntau dua, thiab cov ntaub ntawv tuaj yeem siv, thiab ntau dua, thiab cov ntaub ntawv tuaj yeem ua haujlwm, thiab qhov chaw tuaj txog ntawm Asphalt yog tshuaj xyuas, tsis muaj Tsawg dua 4kg ntawm cov khoom siv uas yuav tsum tau muab khaws cia rau kev siv.
