Premix ntaub pua plag (PC) yog qhov qub kub sib xyaw hauv Is Nrias teb. Nws yog ib qho zoo, kev lag luam, bituminous hnav cov chav kawm sib xyaw kom muab tso ncaj qha rau ntawm dej khi macadam (WBM) ntawm txoj kev nyob deb nroog tsawg. Cov premix ntaub pua plag Nws tseem yog muab nrog ib lub tsho tiv thaiv bituminous xuab zeb kom txo qis kev nkag mus ncaj qha ntawm cov dej nag rau hauv nws.
Ntawm no, Open Graded premix ntaub pua plag yog dab tsi?
Abstract: Qhib cov ntaub pua plag premix yog ib qho tseem ceeb ntawm kev hnav khaub ncaws rau kev tsheb khiav qis mus rau nruab nrab hauv Is Nrias teb. Nws yog ib hom kev hloov pauv pavement hnav cov chav kawm. Qhov no yog tsim los ntawm ntau yam ntawm cov ntsiab lus binder muab los ntawm Indian Road Congress rau qhib qib premix ntaub pua plag.
Tsis tas li ntawd, premix hauv kev tsim kho yog dab tsi? Txhais: Ib yam khoom uas yog tov los yog sib tov los ntawm ob los yog ntau tshaj cov khoom xyaw los yog cov khoom ua ntej siv. Lo lus no feem ntau yog siv rau kev ua vaj tse hauv civil engineering. Premix feem ntau yog hais txog ib yam khoom lossis cov khoom uas sib xyaw ua ke nyob rau theem pib ntawm kev tsim khoom thiab kev faib khoom.
Raws li, bituminous ntaub pua plag yog dab tsi?
Premix Ntaub pua plag (PMC) yog qhov qhib graded bituminous mix uas yog dav siv raws li ib tug overlay nyob rau hauv nroog seem thiab raws li ib tug nto ntawm txoj kev nyob deb nroog nyob rau hauv Is Nrias teb. Lub tsho tiv thaiv xuab zeb feem ntau yog muab los ntawm PMC los tiv thaiv kev nkag ntawm cov dej saum npoo av.
Cov ntaub pua plag hauv kev tsim kho yog dab tsi?
Txoj kev ntaub pua plag zoo ib yam li cov chaw pavement uas twb muaj lawm nrog qib siab dua ntawm cov khoom tiv thaiv skid. Tsis zoo li pavement, Txoj kev ntaub pua plag muaj peev xwm ncab, thiab ua raws li feem ntau ntawm txhua qhov chaw tsis muaj cracking thiab splitting. Txoj kev ntaub pua plag muab hloov tau yooj yim thiab stretchable los tiv thaiv kev nplua rau txhua tus neeg taug kev thiab tsheb.
Pom zoo:
Puas yog olefin yog cov ntaub pua plag zoo?
Olefin thiab polypropylene yog ob lub npe rau ob-feem ntau siv ntaub pua plag fiber ntau tom qab nylon. Olefin tsis yog ruaj li nylon, tab sis nws yog chemically inert thiab resists acid thiab bleach zoo. Olefin yog tov-dyed thiab yog xim tshaj plaws ntawm tag nrho cov fibers. Cov ntaub pua plag olefin yog qhov zoo hauv thaj chaw raug tshav ntuj
Dab tsi yog cov ntaub pua plag siv rau hauv cov phiaj xwm ntom ntom?
Cov ntaub pua plag yog ib zajlus ntawm cov ntaub ntawv rau ib qho kev sib txawv ntawm ib qho, tso tawm raws li cov cim ntawm ib qho axis. Nws yog siv los pom qhov kev faib tawm ntawm cov ntaub ntawv. Raws li xws li nws yog analogous mus rau ib tug histogram nrog xoom-dav bins, los yog ib-dimensional scatter plot
Txoj kev faib cov ntaub ntawv twg muab cov ntaub ntawv sib npaug ntawm cov ntaub ntawv lossis cov kev tshuaj xyuas hauv txhua chav kawm cov ntaub ntawv?
Quantile. txhua chav kawm muaj cov yam ntxwv sib npaug. Ib qho kev faib tawm ntau yog zoo haum rau cov ntaub ntawv faib tawm. Quantile muab tib tus lej ntawm cov ntaub ntawv muaj nuj nqis rau txhua chav kawm
Cov yam ntxwv ntawm cov ntaub ntawv twg yog qhov ntsuas ntawm tus nqi uas cov ntaub ntawv muaj nuj nqis heev?
Variation: Ib qho kev ntsuas ntawm tus nqi uas cov ntaub ntawv muaj nuj nqis sib txawv. ? Kev faib tawm: Cov xwm txheej lossis cov duab ntawm kev sib kis ntawm cov ntaub ntawv hla ntau qhov tseem ceeb (xws li tswb-puab). ? Outliers: Cov qauv piv txwv uas nyob deb heev ntawm feem ntau ntawm lwm cov qauv nqi
Dab tsi yog cov cuab yeej lossis cov ntaub ntawv uas tus Kws Tshawb Fawb xav tau los txheeb xyuas cov ntaub ntawv nug?
Cov ntaub ntawv raug nug hauv chav kuaj ua txhaum cai yog nruab nrog lub tshuab ntsuas ntsuas, ntsuas cov duab digital, infrared thiab ultraviolet lub teeb ci, cov cuab yeej tshuaj ntsuam video thiab cov cuab yeej tshwj xeeb suav nrog cov khoom siv hluav taws xob tshawb pom electrostatic (EDD) thiab cov khoom siv los ua chemistry
