Raws li thaum ntxov thaum ub, tib neeg siv cov hooves ntawm cov tsiaj txhu los tsuj, knead, thiab compact av rau lub hauv paus tsev, dams, thiab ntug dej. Ua ntej nruab nrab - xyoo pua 19th, kev tsim kho sab hnub poob feem ntau yog siv cov pob zeb ua pob zeb, nrog rau kev cog lus tsuas yog nyob ntawm lub ntuj rolling ntawm tsheb. Nws tsis yog txog thaum qhov kev tsim ntawm pob zeb rau cov menyuam hauv xyoo 1858 tias txoj kev loj hlob ntawm cov pob zeb pob zeb pavements tau spurred, thiab nees-drawn rollers maj mam tshwm sim rau compaction, sawv cev rau cov qauv ntxov tshaj plaws ntawm txoj kev cov menyuam. Xyoo 1860, lub tshuab nqus tsev vacuum tau tshwm sim hauv Fab Kis, ntxiv kev txhawb nqa thiab txhim kho kev tsim kho tshuab thiab kev ua haujlwm zoo ntawm cov pob zeb tawg, thiab ua kom cov txheej txheem nrawm dua.
Nyob rau hauv thaum ntxov 20th caug xyoo, crushed pob zeb pavements tau lees paub thoob ntiaj teb raws li qhov zoo tshaj plaws pavement thaum lub sij hawm thiab tau dav saws. Lub tswv yim ntawm compaction maj mam paub, thiab txoj kev rollers tau tshwm sim nyob rau ntau qhov chaw tsim kho. Nyob rau hauv nruab nrab-19th caug xyoo, lub invention ntawm lub internal combustion engine coj zoo kawg li tseem ceeb heev rau txoj kev loj hlob ntawm compaction khoom.
Thawj lub cav hluav taws xob sab hauv- tsav txoj kev cov menyuam tau yug los thaum xyoo pua 20th. Tom qab qhov no tuaj lub pneumatic log tsheb cov menyuam, uas tshwm sim yuav luag ib txhij nrog lub nruas du. Kev tshawb fawb tau ua nyob rau hauv cov nyhuv compaction ntawm static rollers, xaus lus tias ua rau cov menyuam qhov hnyav nce nws linear siab, yog li txhim kho compaction.
Yog li ntawd, rau lub sij hawm tseem ceeb, kev siv zog tau tsom mus rau kev tsim loj -tonnage rollers. Cov log tsheb loj tshaj plaws pneumatic hnyav tshaj 200 tons. Txawm li cas los xij, nyob rau lub sijhawm no, kev hloov pauv ntawm cov yob feem ntau tsom rau kev txhim kho lub zog thiab tsim qauv.
