Ukutywinwa kwegrabile okudityanisiweyo sele kuyindlela eqhelekileyo yokugcina indlela, kwaye wonke umntu uyazi malunga nezilumkiso ngexesha lenkqubo yokwakha. Kodwa bambalwa abantu abakwaziyo ukuba banikele ingqalelo emva kokuba ukwakhiwa kugqityiwe. Makhe sithethe ngesi sihloko namhlanje.

I-synchronized gravel sealing isebenzisa umatshini wokutywina we-synchronous gravel ukuze usasaze i-asphalt binder kunye ne-aggregates yesayizi ye-particle enye kwindlela ehamba ngayo ngexesha elifanayo, kunye ne-binder kunye ne-aggregate ziboshwe ngokupheleleyo phantsi kokuqengqeleka kwe-roller yesondo lerabha. Umaleko wegrabile we-asphalt wenziwe. Izinto ekufuneka ziqwalaselwe emva kokuba ulwakhiwo lugqityiwe zezi zilandelayo:
Emva kokuba ukwakhiwa kugqitywe, ii-aggregates eziye zawa kumphezulu womgca wokutywina kufuneka zihlaziywe. Emva kokuba izinto ezincedisayo zomphezulu zicocwe, i-traffic inokuvulwa.
Abasebenzi abakhethekileyo kufuneka babelwe ukulawula isithuthi sokutywinwa se-synchronous gravel ukuqhuba ngesantya esingaguqukiyo kwiiyure ze-12-24 emva kokuba ivulelwe i-traffic. Kwangaxeshanye, isantya sokuqhuba asiyi kudlula i-20km/h. Kwangaxeshanye, ukunyathela ngesiquphe kunqatshelwe ngokungqongqo ukuthintela ukuxinana kwindlela.
Yintoni esifanele sinikele ingqalelo kuyo emva kokuba ukwakhiwa kokutywinwa kwegrabile okuhambelanayo kugqityiwe? Ngokweenkcukacha zobugcisa bemigangatho yendawo yePhondo laseShaanxi, ukuphinda kusetyenziswe kwakhona kunye nokulawulwa kwezithuthi zizinto eziphambili ezifuna ukuhoywa. Ngaba ucinga ukuba ilungile?
