Asphalt sib xyaw ua los ntawm asphalt tov tsob nroj muaj cov cim ntawm cov yam ntxwv zoo.
Ua ntej, asphalt sib xyaw yog ib qho elastic-yas viscous khoom, uas ua rau nws muaj qhov kub kub nyob ruaj khov thiab tsawg tshaj plaws tawg. Qhov kev ruaj khov no ua kom muaj kev ruaj khov uas asphalt pavement tuaj yeem ua kom muaj kev ua tau zoo nyob rau ntau yam huab cua huab cua.

Thib ob, cov qauv sib xyaw ntawm kev sib xyaw asphalt ntawm kev sib xyaw ua ke yog muaj ntau haiv neeg, thiab cov qauv tsim nyog qauv tsim nyog tau raug xaiv raws li kev tsim kho tshuab engineering. Cov qauv kev coj ua cov hom kev kawm tau suav nrog kev ncua-tuab, pob txha pob txha pob txha thiab ntom-pob txha txheem. Cov qauv no muaj lawv tus kheej cov yam ntxwv. Piv txwv li, tus neeg raug ncua kev kawm kom nruj muaj cov cohesion siab tab sis kub ruaj khov; Thaum lub cev pob txha-khoob qauv muaj qhov kub kub kub muaj zog.
Ntxiv rau, asphalt sib xyaw ua ke txoj kev chim siab muaj qee cov kev sib tw, uas ua rau txoj kev sib tsoo muaj khaub ncaws nag thiab txhim kho kev nyab xeeb tsav tsheb.
Thaum kawg, kev tsim txom ntawm asphalt sib xyaw yog yooj yim thiab nrawm, nrog lub sijhawm nrawm nrawm thiab luv luv, thiab nws tuaj yeem qhib tsheb hauv lub sijhawm. Nyob rau tib lub sijhawm, asphalt pavem kuj tseem tuaj yeem hloov pauv thiab rov ua dua nyob rau theem, uas yog kev lag luam zoo thiab ib puag ncig zoo.
Nws yuav tsum raug sau tseg tias txawm hais tias asphalt sib xyaw muaj ntau yam zoo, kuj tseem muaj qee yam teeb meem, xws li kev laus thiab kev laus tsis zoo. Yog li ntawd, kev kuaj xyuas thiab kev saib xyuas ib txwm muaj thaum siv kom paub tseeb tias nws qhov kev ua tau zoo tau siv.
