Amasimu otshani bokwenziwa aya ngokuya eba yinto evamile futhi asetshenziswa kwezemidlalo zansuku zonke. Uhlelo oluphelele lwezemidlalo yotshani bokwenziwa luqukethe ungqimba lwesisekelo, ungqimba lokucasha, kanye nongqimba lwetshani. Isisekelo asisona nje esinye sezinyathelo ezibaluleke kakhulu ekubekeni utshani bokwenziwa kodwa futhi sisebenza njengesisekelo sensimu yonke. Ikhwalithi yaso ithinta ngqo ukusebenza kanye nesikhathi sokuphila kwensimu. Ngakho-ke, kubalulekile ukubeka phambili isisekelo samasimu otshani bokwenziwa. Ngezansi kunesingeniso esifushane sezinhlobo eziningana zesisekelo ezivamile ezisetshenziswa njengamanje ezinkundleni zemidlalo yotshani bokwenziwa.
1. Isisekelo Sekhonkrithi Sesimende
Ukuthamba: Izinga lokudlula kokuthamba kufanele libe ngaphezu kwama-95%, kanye nokubekezelela okungu-3mm kumbusi wamamitha ama-5.
Ukuthambeka: 3‰-4‰ phakathi nendawo, ngomklamo wokudonsa amanzi we-turtleback. 8‰ wama-curve, 5‰ wama-straight, kanye no-5‰ wezindawo eziyindilinga. Ubuso kufanele bube yisicaba, bushelele, futhi bukhiphe amanzi kahle.
Amandla Nokuzinza: Ubuso kufanele bufane futhi buqine, bungabi nemifantu noma imiphetho ephukile, bube nezihlanganisi eziqondile nezibushelelezi. Sika zibe yizingxenye ezingu-6m x 6m. I-subgrade kumele ihlanganiswe ibe nobukhulu obungaphezu kuka-95%. Ngemva kokusetshenziswa kwe-roller esindayo, qiniseka ukuthi ubuso abunanhlabathi ekhululekile kanye nama-wheel marks abonakalayo.
Isikhathi Sokulungisa: Isikhathi sokulungisa isisekelo siyizinsuku ezingama-21.
Ukubeka Indawo: Ukuze kwakhiwe futhi kubekwe uphawu olunembile, sebenzisa omaka abaqinile nabacacile ukumaka yonke imigqa endaweni.
2. Isisekelo Se-Asphalt
Ukuthamba: Izinga lokudlula kokuthamba kumele libe ngaphezu kwama-95%, kanye nokubekezelela okungu-3mm kumbusi wamamitha amathathu.
Ukuthambeka: <1% ngokuvundlile, <1‰ ngokuvundlile, kanye <4‰ endaweni yokugxuma okuphezulu. Ubuso kufanele bube bushelelezi futhi bube bushelelezi ukuqinisekisa ukuthi amanzi ayaphuma.
Amandla Nokuzinza: Izinto ze-asphalt kufanele kube ngcono ukuthi zingabi ne-wax noma zibe ne-wax ephansi. Indawo eyisisekelo kumele ihlanganiswe ngokuphelele ukuqinisekisa indawo ebushelelezi, engenamabala, engenamiphetho ebolile, kanye namalunga abushelelezi, ayisicaba.
Isikhathi Sokulungisa: Isikhathi sokulungisa isisekelo siyizinsuku ezingama-28. 3. 37 Isisekelo Somhlabathi We-Lime
Ukulingana Kwezinto Ezisetshenziswayo: Izinto ezisetshenziswayo kufanele zibe yinhlabathi enobumba oluncane olunezinhlayiya ezincane ezingadluli ku-15mm, okuqukethwe yi-sulfate okungaphansi kuka-0.8%, kanye nokuqukethwe kwezinto eziphilayo okungaphansi kuka-10%. Sebenzisa impuphu ye-lime emanzi okungenani yeBanga lesi-3. Ngemva kokukhetha inhlabathi efanelekile kanye ne-lime, yenza isivivinyo sokuminyana kwenhlabathi ye-lime esingu-3:7 njalo nge-5,000 m³ (ukuminyana okunzima) ukuqinisekisa ukulawulwa kwekhwalithi yokwakha.
Okuqukethwe Komswakama: Ukulawula okuqukethwe komswakama kuyisinyathelo esibalulekile. Ngokuvamile kuyalulekwa ukugcina okuqukethwe komswakama phakathi kuka-20% no-23%, okungenani kungabi ngaphezu kuka-24%. Ngaphambi kokwakha, imingcele efana nobubanzi bokulawula okuqukethwe komswakama womhlabathi, ukujiya kwenhlabathi enama-lime, kanye ne-tamping kanye ne-rolling coefficient kufanele inqunywe ngokusekelwe ezicini zephrojekthi, isici sokuminyana esiklanyelwe, uhlobo lomhlabathi, kanye nezimo zokwakha.
Izinga Lokuqiniswa: Isici Sokuqiniswa K ≥ 0.95
Isikhathi sokuthunyelwe: Septhemba-30-2025
