Cov txheej txheem kho saum npoo thiab cov kev xav tau ntawm cov cement pob zeb ua haujlwm muaj feem xyuam nrog cov yam ntxwv ntawm engineering.Yog li ntawd, cov cuab yeej siv thiab kev tsim kho siv tau sib txawv raws li qhov yuav tsum tau ua ntawm qhov project.Lub hom phiaj tseem ceeb ntawm choj lawj chiseling yog los daws qhov teeb meem ntawm adhesion ntawm txheej.Lub floating slurry ntawm cov cement qhob choj lawj yog qhov tseem ceeb uas ua rau tsis ua hauj lwm ntawm tus choj lawj dej txheej, tsis ua hauj lwm ntawm interlayer bonding thiab tsis ua hauj lwm ntawm tus choj lawj paving.Yog li, yog tias tus choj lawj laitance tsis raug txiav tawm tag nrho, nyob rau hauv qhov kev txiav txim ntawm kev tsav tsheb thiab kev co, lub laitance yuav ua rau delamination tsis ua hauj lwm vim tsis txaus shear resistance, thiab yuav tawg nyob rau hauv qhov kev txiav txim ntawm cov dej yaig, uas ua rau kev puas tsuaj ntawm kev puas tsuaj. sab sauv asphalt pob zeb txheej..

1. Choj lawj chiseling yuav tsum tsis tsuas yog tshem tawm cov laitance, tab sis kuj tsim ib tug tsis sib xws nto, uas yog, qhov sib txawv ntawm lub ncov thiab troughs ntawm nto tom qab raug chiseled, tus nqi ntawm mil yuav tsum loj, tsuas yog nyob rau hauv no txoj kev yuav cov khaubncaws sab nraud povtseg. yuav tsum ruaj khov.Shaving ntawm semi-rigid pavement puag txheej Qhov kev txiav qhov tob thiab kev ua haujlwm ntawm semi-rigid pavement puag txheej ntawm txoj kev nthuav dav ua ntej tso asphalt pob zeb, nrog rau cov khoom siv chiseling thiab choj lawj.

2. Lub hom phiaj ntawm ob qhov kev kho mob saum npoo no yog ua kom cov pob zeb asphalt pavement thiab lub hauv paus txheej tuaj yeem ua kom ruaj khov, thiab tiv thaiv dej seepage, lub qub yog chisel polished qub cement qhob pavement rau hauv qhov ntxhib nto, tom kawg. Nws yog tshem tawm cov log tsheb ntawm lub tshav dav hlau khiav.Lub hom phiaj ntawm ob yog los kho thiab kho cov kev tiv thaiv skid thiab zoo txhim kho lub peev xwm tiv thaiv kev co thiab deformation.

3. Lub chiseling ntawm cement pavement thiab tshav dav hlau khiav Txoj kev chiseling yuav tsum tau ntawm cement pavement thiab tshav dav hlau khiav yog los tiv thaiv tsheb los ntawm slipping thaum tsav tsheb thiab tsaws.
