Kev tsim qauv ntawm asphalt pavement qauv yog ib qho tseem ceeb ua ntej hauv kev tsim vaj tsev, ncaj qha txiav txim siab ntawm pavement load-cov kabmob muaj peev xwm, kev pabcuam lub neej, thiab cov nqi tu. Qhov kev tsim no yuav tsum muaj ntau yam - qhov sib txawv raws li qhov ua haujlwm tiag tiag, tsis yog cov txheej txheem txheej txheem yooj yim. Nws qhov kev tshawb fawb thiab kev xav tau ncaj qha cuam tshuam rau kev ua haujlwm ruaj khov ntawm txoj kev taug kev thoob plaws nws lub neej tag nrho. Daim phiaj tsim qauv ua tiav yuav tsum ua raws li qhov kev xav tau ntawm lub cev, nkag siab txog ntau yam tseem ceeb, uas tuaj yeem muab faib ua plaub theem tseem ceeb hauv qab no:
Kev Tshawb Fawb Txog Kev Ua Haujlwm Ua Ntej: Lub hauv paus ntawm kev tsim qauv
- Cov lus qhia tseem ceeb hauv kev tshawb fawb: tsom mus rau ob qhov tseem ceeb: kev xav tau ntawm kev thauj mus los thiab ib puag ncig, muab cov ntaub ntawv txhawb nqa rau kev tsim qauv tom ntej.
- Daim ntawv ntsuam xyuas kev xav tau tsheb: Ua kom raug kwv yees cov ntaub ntawv tseem ceeb xws li ntev - lub sijhawm tsheb thauj mus los thiab kev faib ua feem ntawm cov tsheb hnyav ntawm txoj kev, ua lub hauv paus tseem ceeb rau kev txiav txim siab pavement thickness thiab lub zog ntawm cov qauv. Piv txwv li, siab - tsheb thauj mus los, hnyav- cov seem thauj khoom yuav tsum muaj cov txheej txheem ntxiv, thaum qis - cov ceg tsheb thauj mus los tuaj yeem muaj cov qauv tsim kom zoo thiab yooj yim.
- Environmental condition assessment: Kev txheeb xyuas cov yam ntxwv ntawm huab cua hauv cheeb tsam. High- thaj chaw kub yuav tsum tsom rau rutting resistance design, cov cheeb tsam txias yuav tsum ntxiv dag zog rau khov-thaw tiv thaiv tsim, thiab cov chaw los nag yuav tsum tsom rau kev txhim kho cov qauv dej kom tsis txhob muaj dej nag nkag mus rau lub hauv paus txheej.
Standard Adaptation and Structural Layer Design: Cov ntsiab lus tseem ceeb ntawm txoj kev npaj
- Ua raws li cov qauv kev lag luam: nruj me ntsis raws li cov qauv tam sim no, xws li Suav JTG-D50 tus qauv thiab American AASHTO tus qauv, kom ntseeg tau tias kev ua raws cai thiab kev tshawb fawb siv tau ntawm txoj kev npaj.
- Clear txheej faib: Hom asphalt pavement structures xav kom meej meej ntawm qhov chaw ua haujlwm ntawm txheej txheej, txheej txheej, txheej txheej subbase, thiab subgrade, nrog rau txhua txheej ntxiv thiab sib koom tes nrog lwm tus.
- Cov ntsiab lus tseem ceeb rau txhua txheej: Cov txheej txheej saum npoo yuav tsum siv hnav- tiv taus thiab tiv thaiv - nplua asphalt sib tov kom tiv thaiv tsheb thauj khoom thiab kev yaig ib puag ncig; lub hauv paus thiab subbase khaubncaws sab nraud povtseg kom muaj zog thiab stability, bearing thiab kis loads; lub subgrade, raws li lub hauv paus, yuav tsum muaj zoo compaction thiab bearing peev xwm.
Parameter Quantification thiab Implementation Connection: Qhov tseem ceeb rau kev npaj ua
- Precise parameter quantification: xam cov thickness ntawm txhua txheej txheej raws li cov ntaub ntawv ntim tsheb, thiab txiav txim siab cov khoom faib raws li hom tsheb. High -viscosity asphalt thiab siab- lub zog aggregates yuav tsum yog qhov tseem ceeb rau qhov hnyav-load seem los txhim kho shear thiab qaug zog tiv thaiv. - Txhais lub hom phiaj kev ua tau zoo: Lub phiaj xwm yuav tsum txheeb xyuas qhov ua tau zoo thiab kev pabcuam lub neej, ua tiav cov qauv kev xav tau los ntawm kev xaiv cov khoom siv thiab kev ua kom zoo dua qub.
- Txhais rau hauv cov lus qhia kev tsim kho: Qhia meej meej cov qauv khoom, cov khoom siv, thiab kev faib cov neeg ua haujlwm, hloov lub tswv yim tsim los ua ib txoj kev npaj tsim kho kom ua tiav kom ua tau zoo - siv tau zoo.
