Asphalt sib tov tsim los ntawm asphalt mixing cog muaj cov yam ntxwv zoo kawg li.
Ua ntej, asphalt sib tov yog cov khoom siv elastic-yas viscous, uas ua rau nws muaj qhov kub thiab txias stability thiab tsis tshua muaj kub tawg. Qhov kev ruaj ntseg no ua kom ntseeg tau tias asphalt pavement tuaj yeem tswj tau qhov kev ua tau zoo nyob rau hauv ntau yam kev nyab xeeb.

Qhov thib ob, cov qauv sib xyaw ntawm asphalt sib xyaw yog ntau haiv neeg, thiab cov qauv tsim nyog tuaj yeem xaiv tau raws li qhov xav tau ntawm engineering. Cov txheej txheem ntau yam muaj xws li ncua kev kawm-dense qauv, skeleton-void qauv thiab ntom-skeleton qauv. Cov qauv no muaj lawv tus kheej yam ntxwv. Piv txwv li, lub ncua kev kawm ntawv-dense qauv muaj siab cohesion tab sis tsis zoo kub kub stability; thaum lub cev pob txha-void qauv muaj siab kub stability.
Tsis tas li ntawd, asphalt sib tov pavement muaj qee qhov kev ntxhib los mos, uas ua rau cov pavement muaj kev tiv thaiv zoo rau hnub los nag thiab txhim kho kev nyab xeeb ntawm kev tsav tsheb.
Thaum kawg, kev tsim kho ntawm asphalt sib tov yog yooj yim thiab ceev, nrog kev ceev ceev thiab lub sijhawm tu ncua, thiab nws tuaj yeem qhib tsheb khiav hauv lub sijhawm. Nyob rau tib lub sijhawm, asphalt pavement tseem tuaj yeem hloov pauv thiab rov ua dua tshiab hauv cov theem, uas yog kev lag luam zoo thiab ib puag ncig zoo.
Nws yuav tsum raug sau tseg tias txawm hais tias asphalt sib tov muaj ntau qhov zoo, kuj tseem yuav muaj qee qhov teeb meem, xws li kev laus thiab qhov kub tsis zoo. Yog li ntawd, kev tshuaj xyuas thiab kev saib xyuas tsis tu ncua yuav tsum tau siv thaum siv los xyuas kom meej tias nws qhov kev ua tau zoo yog siv tag nrho.
