Raws li ib qho novice uas nyuam qhuav nkag mus rau txoj kev txij nkawm kev sib txawv ntawm txhua yam, qhov sib txawv ntawm kev kho mob asphalt thiab siv tau los ntawm kev kho mob asphalt thiab siv tau los ntawm kev kho mob asphalt thiab siv tau los ntawm kev sib txawv

[1] Cov kab mob asphalt ntawm asphalt pavement /
/
muaj kev puas tsuaj rau asphalt rau asphalt mus rau asphalt mus rau asphalt mus rau asphalt pavement: ruts, tawg, thiab potholes. Cov kab mob no muaj ntau thiab loj heev, thiab yog ib qho ntawm cov teeb meem tseem ceeb uas tau hais raws txoj kev loj Rutting yog ib lub zeem-puab tsim los ntawm kev txuam nrog deformation nyob hauv txoj kev tsheb ciav hlau raws li kev tsav tsheb. Rutting txo qhov smoothness ntawm txoj kev nto. Thaum lub ruts ncav cuag ib qho tob ntxiv, vim dej tsub zuj zuj hauv Ruts, cov tsheb feem ntau yuav xaub thiab ua rau muaj kev sib nraus. Rutting yog feem ntau tshwm sim los ntawm kev tsim qauv tsis tsim nyog thiab kev hnyav dhau ntawm tsheb.

Cov khoom siv emulthified yog ib qho "hauv lub zos roothed hauv zos nrawm asphalt cia ". Cov koob tshiab tam sim no yog cov khoom siv as-tshaj plaws hauv Suav teb uas sib txuas lus kub ceev, lub zog txuag thiab kev tiv thaiv ib puag ncig. Ntawm cov khoom lag luam, nws yog cov khoom siv cua sov ncaj qha. Cov khoom tsis tsuas yog muaj cov cua sov ceev ceev, txuag cov roj, thiab tsis txhob ua kom ib puag ncig. Nws yog ib qho yooj yim ua haujlwm. Tsis siv neeg lub zog preheating tshem tawm cov teeb meem ntawm ci lossis tu asphalt thiab pipelines. Lub sijhawm ua haujlwm mus ncig ua si lub voj voog tso cai rau cov asphalt kom nkag mus rau hauv rhaub, tsis muaj plua plav, asphalt twj, thiab asphalt raws li xav tau. Nws muaj cov zaub kub ntawm cov dej, chav hluav taws xob chav, siv hluav taws xob, tag nrho cov uas tau nruab rau (sab hauv) lub tank los tsim ib qho qauv.

Thaum siv cov cua sov roj bitumen tank, nws yuav tsum tau sau tseg tias ntev dua ntawm cov roj basiden tank, cov kev cuam tshuam ntau dua yuav yog qhov zoo tshaj ntawm babumen. Yog li ntawd, thaum siv cov roj thermal roj asphalt tank, koj yuav tsum kos rau hauv qab ntawm lub tank ib xyoos ib zaug los txiav txim siab seb cov roj cua sov asphalt tank xav tu. Tom qab ib nrab ib xyoos ntawm kev siv, koj tuaj yeem sim nws. Thaum nws pom tias cov tshuaj tua kab mob antioxidants lossis muaj cov ecurogen rau cov roj, koj yuav tsum tau ntxiv cov khoom siv hluav taws xob kom zoo nkauj, lossis ua kom cov khoom siv cua sov cov roj cua sov. Vam tias feem ntau ntawm cov neeg siv khoom siv txawm tias koj paub siv nws, koj kuj yuav tsum paub yuav ua li cas cov cua sov roj tso tsheb hlau.

Hloov cov khoom siv Asphalt siv Asmesl Nws cov hniav muaj lub hardness siab, siab linear ceev ntawm cov txav disk, thiab qhov sib txawv tuaj yeem hloov kho rau 0.15mm. Nws yog qhov haum rau kev ua ntau lub polymer-hloov echalts, xws li sbs, pe, thiab lwm yam.

Koj paub ntau npaum li cas txog cov ntawv thov cuam tshuam ntawm cov khoom siv inefulthified asphalt? Raws li cov chaw tsim khoom tshwj xeeb hauv kev tsim cov khoom siv asphalt, txheej txheem tsim khoom ntawm peb cov khoom siv emulsified? Tom ntej no, peb cov neeg ua haujlwm yuav muab lus qhia rau koj.
