Joalokaha bohle re tseba, micro-surfacing le slurry ho tiisoa ka bobeli ke mekhoa e tloaelehileng ea ho thibela ho thibela, 'me mekhoa ea matsoho e boetse e tšoana, kahoo batho ba bangata ha ba tsebe ho li khetholla ha li sebelisoa, kahoo mohlophisi oa Sinoroader a ka rata nka monyetla ona E re ke o bolelle phapang pakeng tsa tsena tse pedi.
Liphapang tse 'ne tse kholo lipakeng tsa microsurfacing le slurry sealingLiphapang tse 'ne tse kholo lipakeng tsa microsurfacing le slurry sealing
1. E sebetsa libakeng tse fapaneng tsa litsela: Micro-surfacing e sebelisoa haholo-holo bakeng sa tlhokomelo e thibelang litsela tse kholo le ho tlatsa li-ruts tse khanyang. E boetse e loketse li-anti-slip wear layers tsa litsela tse kholo tse sa tsoa hahoa. Setiiso sa slurry se sebelisoa haholo-holo bakeng sa tokiso ea litsela tsa bobeli le ka tlase, hape se ka sebelisoa ho tiisoa ka tlase ea litsela tse ncha.
2. Boleng ba li-aggregates bo fapane: tahlehelo ea abrasion ea li-aggregates tse sebelisoang bakeng sa micro-surfacing e lokela ho ba ka tlase ho 30%, e leng ntho e thata ho feta tlhokahalo ea ho feta 35% bakeng sa li-aggregates tse sebelisetsoang ho tiisa slurry; li-aggregates tse sebelisetsoang ho etsa micro-surfacing li feta ka sefeng sa 4.75mm Lehlabathe le lekanang le thepa ea maiketsetso ea liminerale e lokela ho ba holimo ho 65%, e leng holimo haholo ho feta 45% e hlokahalang ha e sebelisetsoa ho tiisa seretse.
3. Litlhoko tse fapaneng tsa tekheniki: tiiso ea slurry e sebelisa mefuta e sa tšoaneng ea asphalt e sa fetotsoeng ea emulsified, ha sebaka se senyenyane se sebelisa sekontiri se fetotsoeng ka potlako, 'me lihlahisoa tse setseng li phahame ho feta 62%, tse phahameng ho feta tsa slurry seal. Sebelisa asphalt e entsoeng ka holimo ho feta tlhokahalo ea 60%.
4. Lipontšo tsa moralo oa metsoako e 'meli li fapane: motsoako oa micro-surface o tlameha ho kopana le index ea ho roala ha lebili le metsi ka mor'a ho kenngoa metsing ka matsatsi a 6,' me ha ho hlokahale tiiso ea slurry; motsoako oa micro-surface o ka sebelisoa bakeng sa ho tlatsa rut, 'me motsoako o na le tlhokahalo ea ho roala lebili la 1000 The lateral displacement ea sampuli ka mor'a hore tlhahlobo e fokotsehe ho feta tlhokahalo ea 5%, ha slurry seal layer e sa ka ea e-ba teng.
Hoa bonahala hore le hoja micro-surfacing le slurry sealing li tšoana libakeng tse ling, li hlile li fapane haholo. Ha u li sebelisa, u tlameha ho khetha ho latela maemo a sebele.
