Umahluko omkhulu omine phakathi kwe-microsurfacing kunye nokutywinwa kodaka
Njengoko sonke sisazi, i-micro-surfacing kunye nokutywinwa kodaka zombini ziyindlela eqhelekileyo yokukhusela, kwaye iindlela zencwadana nazo ziyafana, ngoko ke abantu abaninzi abazi ukuba bangazihlula njani ekusebenziseni okwenyani, ngoko umhleli weSinoroader angathanda thatha eli thuba Ndivumele ndikuxelele umahluko phakathi kwezi zinto zimbini.
1. Isebenza kwiindawo ezahlukeneyo zendlela: I-Micro-surfacing isetyenziselwa ikakhulu ukugcinwa kokuthintela iindlela kunye nokuzaliswa kweeruts ezikhanyayo. Ikwafanelekile kwiileya ezichasene nokutyibilika koohola bendlela abasanda kwakhiwa. Isitywina esiludaka sisetyenziswa ikakhulu kulondolozo lothintelo lweendlela zesibini nangaphantsi, kwaye lunokusetyenziswa nakwitywina elisezantsi leendlela ezintsha.
2. Umgangatho we-aggregates wahlukile: ukulahleka kwe-abrasion yee-aggregates ezisetyenziselwa i-micro-surfacing kufuneka ibe ngaphantsi kwe-30%, engqongqo ngaphezu kweemfuno ezingekho ngaphezu kwe-35% kwii-aggregates ezisetyenziselwa ukutywinwa kwe-slurry; I-aggregates esetyenziselwa i-micro-surfacing idlula kwi-4.75mm isisefu I-santi elingana nemathiriyeli yeminerali eyenziweyo kufuneka ibe phezulu kune-65%, ephezulu kakhulu kuneemfuno ze-45% xa isetyenziselwa ukutywinwa kodaka.
3. Iimfuno ezahlukeneyo zobuchwepheshe: isitywina se-slurry sisebenzisa iintlobo ezahlukeneyo ze-asphalt e-emulsified engatshintshiyo, ngelixa i-micro surface isebenzisa i-asphalt e-emulsified eguqulwa ngokukhawuleza, kwaye umxholo oseleyo uphezulu kune-62%, ephezulu kune-slurry seal. Sebenzisa i-asphalt e-emulsified ephezulu kunemfuno ye-60%.
4. Iimpawu zokuyila zemixube emibini zihluke: umxube we-micro-surface kufuneka uhlangane nesalathisi sokugqoka isondo esimanzi emva kokucwiliswa emanzini iintsuku ezi-6, kwaye i-slurry seal ayifuni; umxube we-micro-surface ungasetyenziselwa ukuzaliswa kwe-rut, kwaye umxube unomthwalo wevili lomthwalo ofunekayo we-1000 I-lateral displacement yesampuli emva kovavanyo yayingaphantsi kwemfuno ye-5%, ngelixa i-slurry seal layer ayizange.
Kuya kubonakala ukuba nangona i-micro-surfacing kunye nokutywinwa kodaka kuyafana kwezinye iindawo, ngokwenene zahluke kakhulu. Xa uzisebenzisa, kufuneka ukhethe ngokweyona meko.
