Kev tsheb ciav hlau, lossis taug qab rau luv luv, nws yog tsuas yog siv nyob rau hauv txoj kev tsheb ciav hlau. Kev tsheb ciav hlau txoj kev koom tes nrog hloov, yog li ntawd lub tsheb ciav hlau tuaj yeem muaj kev nyab xeeb. Raws li peb txhua tus paub, kev tsheb ciav hlau yog tsim los ntawm ob txoj kev sib tw sib txuas, cov hlua hlau yog tsau rau ntawm cov railway sleepers thiab ballast yog nyob rau hauv tus railway sleepers. Txoj kev tsheb nqaj hlau yog muaj cov hlau ciav hlau, hlau Railwway ntses, thiab lwm yam ntawm kev tsheb ciav hlau zoo li qub thiab kev sib tw ntawm kev ntsug thiab tom qab.
Railway Cov lemfeem ntau ua los ntawm high -} Zoo steel, tshwj xeeb ib hom ntawmCov Hlau Hlau, Thaum lub hauv paus yog feem ntau ua tsim los ntawm pob zeb crushed, gravel, lossis pob zeb ua. Cov ntsia hlau loj tsim los tuav cov khoom hnyav thiab kev kub ceev thiab feem ntau ua kom zoo li manganese thiab chromium rau ntxiv lub zog thiab hnav tsis kam. Cov ntaub ntawv trackbed muab kev txhawb nqa, tso kua dej, thiab kev ruaj khov.
