lub luag hauj lwm ntawm cov ntxhia hmoov
1. Sau asphalt sib tov: Nws yog siv los sau qhov sib txawv ua ntej asphalt sib tov thiab txo qhov tsis muaj qhov sib piv ua ntej sib tov, uas tuaj yeem ua rau kom cov compactness ntawm asphalt sib tov thiab kuj txhim kho cov dej tsis kam thiab durability ntawm asphalt sib tov. Mineral nplua kuj qee zaum hu ua fillers.

2. Txhawm rau kom muaj kev sib koom ua ke ntawm bitumen: Vim tias cov hmoov ntxhia muaj ntau cov zaub mov, cov zaub mov yooj yim ua ke nrog asphalt molecules, yog li asphalt thiab ntxhia hmoov tuaj yeem ua haujlwm ua ke los tsim cov asphalt cement, uas tuaj yeem ua rau cov adhesion ntawm asphalt sib tov.

3. Txhim kho txoj kev zoo: Asphalt tsis yog yooj yim rau kev sib hais haum xwb, tab sis kuj yuav ua rau tawg vim qhov kub thiab txias thiab lwm yam cuam tshuam. Yog li, ntxiv cov ntxhia hmoov pab txhim kho lub zog thiab shear tsis kam ntawm asphalt sib tov, thiab tuaj yeem txo qhov tawg thiab tawg ntawm asphalt pavement.

Vim li cas ho tsis tau lub nruas asphalt tov cog ntxiv cov ntxhia hmoov?

Kev sib xyaw cua sov thiab sib xyaw ntawm lub nruas asphalt sib xyaw cov nroj tsuag yog nqa tawm hauv tib lub nruas, thiab sab hauv ntawm lub nruas tuaj yeem muab faib ua ib qho chaw qhuav thiab qhov chaw sib xyaw. Tsis tas li ntawd, lub tshuab tshem tawm cov plua plav yuav tsum tau nruab rau ntawm qhov kawg ntawm qhov kev taw qhia ntawm cov cua kub ntws, uas yog, nyob rau sab nraud ntawm lub qhov cub, vim yog tias nws tau nruab rau tib sab, cua yuav tshem tawm qhov kub. huab cua ntws, yog li cov plua plav tshem tawm ntawm lub nruas hom asphalt mixing cog Nws yog ntsia rau qhov kawg ntawm thaj tsam nplawm. Yog li ntawd, yog tias cov hmoov ntxhia ntxiv rau lub nruas, lub hnab lim yuav tshem cov hmoov ntxhia pov tseg raws li cov plua plav, yog li cuam tshuam qhov kev sib tw ntawm asphalt sib tov. Yuav kom suav tau, lub nruas hom asphalt mixing cog tsis tuaj yeem ntxiv cov hmoov ntxhia.
